Choice of Brad Point Drill Bit Sale
2021年11月16日How to choose the drill bit for brad point drill bit sale
When choosing any bit, please consider the following factors:
1. The size of the hole to be drilled
2. The size of the handle (should be as large as possible but also suitable for your drill)
3. Do you need a flat-bottomed hole
4. What is your entry rate (for quick production work, the large angle groove on the Brad bit will provide cleaner holes)
5. Your tolerance for ambiguity at the edge of the hole
6. The direction of the hole (band pattern, twill pattern, etc.)
7. The type of wood you are drilling (for example, a slightly larger drill should be used to drill pilot screw holes in hardwood instead of softwood).
The drill bit descriptions of our drill bits suppliers can help you determine whether a particular drill bit is suitable for the application you are considering. No matter what you choose in the end, let the tool do the work for you. If you have to cut with excessive pressure, the drill bit will become dull and should be sharpened or replaced immediately.

How to choose the best drill bit
There are many different types of high-performance Drill Bits Wholesale drill bits, each of which is designed to perform well in specific types of tasks. In addition to determining which style is best for your job, you should also understand the quality of the drill bit, which will not only affect the hole itself (concentricity, smoothness, etc.), the life of the drill bit, and whether it will even cut what you are dealing with Material. Higher quality drill bits are generally more expensive than lower quality drill bits. Three general factors that affect the overall drill bit quality:
The general quality of steel (hardness, alloy content)
Machining of grooves (if any) and cutting edges
The roundness of the drill bit (should be a perfect circle)
Regardless of quality issues, you should try to use drills that are suitable for the job you are doing. For example, although most people always use them for this purpose, standard twist drill bits are not designed for drilling screw holes; cone-point drill bits are, and they do better because they leave enough on the side of the hole Material to allow all threads to bite.
As our shoemaker said, "the last one is first." For starters, last is the form of making shoes or boots. The representation of your feet-a bit-includes style lines, heel height, toe shape, attitude. The most important and tricky part of the whole job. In my work, everything starts here. Shoes can be cute, but if they don’t fit your feet, they won’t last. They can cause injury and possibly damage your feet. Since shoe lasts are made or adjusted according to the specifications of each customer, their uniqueness in line, curve and character is beautiful. Each has its own story to tell at the end. Understanding how measurement, tracking, and exercise work together is a hard-won skill. Once again, gain experience through trial and error, learn from skilled craftsmen and not give up on the manufacturer that marks success.

Introduction of Threading Tools Wholesale
2021年11月9日 お仕事
Finding that an uncalibrated thread gauge can damage your machine thousands of millimeters is daunting for anyone. And, although outsourcing calibration is tempting, you can do it yourself with some time, care, and a few simple steps.
If you are curious about how to calibrate thread gauges in mechanical machinery, then look no further. This article will guide you step by step through the entire process to make it easier to understand.
1. Clean your machine
You first need to make sure that all machine parts are clean. Use a suitable solvent to thoroughly clean all surfaces. Keep the solvent bucket at a certain distance to avoid splashing.
2. Check for contamination
Now, use a microscope or magnifying glass assembly to check for any dirt or debris on the thread gauge. You can also use a high-quality camera with a macro lens to zoom in on every detail of the thread gauge measuring device for inspection. Use a suitable solvent to clean all dirt and debris, and let it dry well before proceeding.
3. Let it air dry
Wait for the parts of the measuring device to dry before continuing. This may seem like a strange step, but it is as important as the other steps in this list. Keeping the equipment dry can produce inaccurate results.
4. Prepare the internal thread
Now, prepare an internal thread on your machine, on which you intend to calibrate your tool. You can perform this process manually or with a bicycle lathe and lead screw to easily accomplish this job.
Please note that thread gauge calibration is not common because manual calibration is more accurate than automatic calibration. If you choose to use automated machines, this process will be affected, and your results will not be what you expect. Remember, accuracy is the most important thing in the calibration process of any machine.
5. Calculate thread size
You first need to determine the size of your thread. You can read the manufacturer’s specifications from the user manual or contact the manufacturer for more detailed information. This step is the key factor that needs to be accurately determined.
If you don’t know what size it is, then you have to measure it yourself. But you need to use a pre-calibrated thread gauge, if not, you will be in trouble. Please note that these measurements should not exceed 10 microns, because any larger measurements may damage your machine, and even in some extreme cases may hurt you!
The best way is to check the thread authentication. This way, you know that you will use the most accurate tool to calibrate the thread gauge.
6. Connect the pressure gauge with a screw
Now, fix the internal gauge to the central lead screw of the machine. You can use automatic thread tools or bicycle lathes and lead screws to accomplish this task. Make sure your internal thread gauge is firmly attached to the lead screw.
7. Set the pitch circle diameter
Now, set the pitch circle diameter on the positioning device and make sure it is properly aligned with the other parts of the machine. Correct alignment will ensure that you are accurate in all aspects when taking measurements. Make sure that the pitch diameter is parallel to the main shaft and follows its circular motion correctly.
8. Connect the lead screw to the pitch diameter
Now you need to measure the thread gauge. First, you need to connect the lead screw to the pitch diameter. This process should be done by hand or using a combination of electric drill or lathe and lead screw.
9. Measure the size of the meter multiple times
You need to measure the gauge size at several points on the screw thread, and then continue to do so until you reach the original starting point. If you wish, you can also use automatic tools in this process, but as long as you take precision and accuracy into consideration when making the measurement, it is not necessary.
You should perform these steps multiple times to further improve the accuracy of the measurement.
10. Comparison and analysis of measurements
Now you need to compare the measurement results with the pitch circle diameter and the gauge size. If the two do not match in this step, you will have to go back to step 3 and try again or determine why there is a difference. There may be a problem with your thread or internal thread gauge, and you may have to correct it before proceeding.

Precautions For Threading Tools
2021年8月26日
In the early days, the threading tools were mainly used for the traction of the wall and the road and later developed into the optical cable of the sewer to wait for the traction of the line. The threader has the advantages of saving time, labor and improving work efficiency. It can be used for cleaning telecommunications pipelines and laying out optical cables, cables, and plastic sub-pipes. When in use, the FRP-covered rod is firstly led out from the lead wheel, and then connected with the corresponding metalhead, and then penetrated into the pipeline. When used for cleaning, the guide head drives the cleaning tool to clean the pipeline; when used for laying cables, the steel wire or iron wire can be brought in first, and then the steel wire or iron wire can be used to pull the cable into the pipe.
How To Use Threading Tools
2021年8月19日
After the staff has completed the threading, all cables should be fully tested for continuity. Test method: Strip all the cores of the cables at both ends to expose the copper cores. Set the digital multimeter to the continuity test position at one end, and connect the two test leads to a pair of cable cores steadily; at the other end, touch the pair of cable cores briefly. If you can hear the intermittent beep sound at the end of the watch, it is OK, and the core of each cable must be measured. The problems that can be found by this test are disconnection, disconnection, and wrong labeling.
So if you want to thread, you still need professional staff to help. The same is true for people who want to engage in cutting tools wholesale. All walks of life have their own rules and standards, and the wholesale industry naturally has its standards and requirements.
Types Of Wood Auger Drill Bit

Spiral drill bit classification:
1. The cutting tool used for the soil spiral drill is shovel-shaped wear-resistant alloy bucket teeth and picks, which are mainly used for soil layers above the groundwater level, sand layers, compact sand layers with a small amount of clay, and sand with small particle diameters. There is no loop drilling in the layer. The structure is a straight spiral, and there are three types of bullet-head single screw, double-head single screw, and double-head double screw. The single screw bit is suitable for drilling into the gravel layer and the clay layer with good cementation due to easy slag removal and low rotation resistance. The double screw bit has strong soil carrying capacity and good guiding performance, suitable for drilling into loose formations and soft and hard interbeds. Strata. The drill diameter is 400-2000mm.
2. Rock auger bit The cutting tool used for the rock auger bit is a pick with tungsten-cobalt carbide welded on the tip. Mainly used for non-circular drilling in Fenghua bedrock, well-cemented pebble and gravel strata, and permafrost layers with various drawings. The structure can be straight snails and cone snails. There are various types according to the formation and the performance of the drill bit. Pitch HSS cobalt drill bit, single head single screw, double head single screw, double head double screw drill bit. The drill diameter is 400-2000mm.
We use drill bits many times, and the drill bits used in different situations are different, and the HSS cobalt drill bit is also a kind of drill we often use. So what should we pay attention to when using drills?
Re-grinding the drill in a timely manner can increase the use and regrind times of the drill, extend the life of the drill, and reduce production costs and expenses. Usually measured with a tool microscope, the wear depth should be less than 0.2mm within the full length of the two main cutting edges. When regrinding, 0.25mm should be removed. Ordinary fixed shank drills can be reground 3 times, and undercut drills can be reground 2 times. Too much grind will reduce the quality and accuracy of the drilling, which will cause the finished circuit board to be scrapped. Excessive grinding effect is counterproductive.
When ordering the manufacturer’s drill bit, 4% of the drill bit shall be randomly inspected to see if it meets the requirements. And 100% of the nicks, scratches and cracks are inspected with a microscope of 10 to 15 times.
And wood auger drill bit manufacturers also need to be tested, so they are still very secure when used. www.jeejatools.com

Notes On The Wood Auger Drill Bit
2021年7月9日A drill bit is a tool that rotates and has the cutting ability at the tip. The most common ones we use are the wood auger drill bit and the HSS cobalt drill bit. So what should we pay attention to when using bricks?
The dust suction effect of the drill press is better, and the dust suction air can reduce the temperature of the drill bit, and at the same time, it takes away the dust and reduces the high temperature caused by friction.
When sharpening the drill, try to make the two main cutting edges of the drill symmetrical, so that the radial forces of the two main cutting edges cancel each other out to prevent the drill from deviating and expanding the hole diameter.
When due to wear and its wear diameter is reduced by 2% compared with the original, the drill bit is scrapped.
The substrate stack, including the upper and lower pads, should be firmly positioned and laid flat in a hole-to-slot positioning system on the worktable of the drilling machine. The use of adhesive tape should prevent the drill bit from drilling on the tape to make the drill bit stick to the chips, causing difficulty in chip removal and broken drills.
Of course, the use of HSS cobalt drill bit or other bricks also needs to pay attention to these. www.jeejatools.com

Diamond cup grinding wheel is not commonly used in our homes, but there are still many uses of Diamond cup grinding wheels in many places. So what are the advantages of Diamond cup grinding wheels?
Low grinding force and low grinding temperature: The hardness and wear resistance of diamond abrasive grains are high, and the abrasive grains can keep sharp for a long time and are easy to cut into the workpiece. When using resin-bonded diamond grinding wheels to grind cemented carbide, the grinding force is only 1/4 to 1/5 of that of ordinary grinding wheels. The thermal conductivity of diamond is very high, 17.5 times that of silicon carbide, and the cutting heat is quickly transferred out, so the grinding temperature is low.
The workpiece to be ground is of high precision and good surface quality: the roughness of the surface and the edge of the carbide tool is much lower than that of the boron carbide grinding wheel when the diamond cup grinding wheel is used to grind the carbide tool. Sharp, the durability of the tool can be increased by 1 to 3 times. The roughness of the workpiece processed by the Diamond cup grinding wheel is generally 0.1~0.025μm, which can improve the finish by 1~2 levels compared with ordinary grinding wheel grinding.
Just like Tungsten carbide hole saws , they have become the choice of many people because of their advantages. www.jeejatools.com

Many drill bits can be seen around us, the most common one is the wood auger drill bit . So today we will learn about the problems and causes of the wood auger drill bit.
The drill bit breaks during drilling, which may be caused by the lip clearance angle are too small or the drilling speed is too high, the feed is large, or the bit is dulled and continues to press.
When the cutting edge breaks during drilling, it may be caused by hard spots in the material of the workpiece or too fast feed, improper selection of the drilling speed, and no simultaneous cutting during drilling.
When drilling, only one chip is discharged, which may be the reason that the two cutting edges are not equal in length or the half-angle of the drill tip is not equal.
The squeaking sound when drilling may be caused by uneven drilling or the dullness of the drill bit.
The above problems HSS cobalt drill bit may also be encountered, so pay more attention when using it. www.jeejatools.com

Regarding the use of wood drill bits, we usually have a lot of them, but in some special cases, ordinary wood drill bits do not affect them. This is where we will need the help of an extra long wood drill bit . So what should we do after using the extra long wood drill bit?
1. After the drill is used, it should be checked immediately for damage, passivation and other bad conditions should be immediately polished and trimmed;
2. The drill bit should be seated when storing it, and it is convenient and time-saving when it is retrieved later, which saves the time to search for the drill bit;
3. When drilling through holes, when the drill bit is about to drill through for an instant, the torque is the largest, so at this time, lighter pressure is required to advance the tool slowly to prevent the bit from twisting due to excessive force;
4. The drilling hole is too large, which may be caused by the unequal half-angle of the drill tip or the deviation of the static point, the deviation of the spindle, etc.
The above are the precautions for the use of an extra-long wood drill bit. For more details, please visit TCT circular saw blades . www.jeejatools.com

We have found that many electricians use many auxiliary tools in the process of threading. These auxiliary tools can be collectively referred to as threading tools. But not everyone can use threading tools. The use of threading tools has certain operating skills and difficulties, so it is naturally dangerous, so pay attention to protect your safety when using threading tools.
Before construction, you must carefully review the construction drawings of other professions, especially the construction drawings of civil structures, water, electricity, and ventilation construction drawings. Because the length of the horizontal routing will have a certain impact on the level of the system, and the construction drawings of civil structures, water, electricity, and ventilation construction drawings have the greatest impact on the direction of the pipeline routing of the horizontal wiring subsystem. Indicate the direction and elevation of other professional pipelines and the specifications and models of various pipelines on the large-scale drawing, and work out the optimal pipeline construction plan to meet the shortest pipeline route and easy installation requirements.
In addition, you should also be fully prepared when using cutting tools to avoid unnecessary harm. And cutting tools wholesale should pay more attention to safety. www.jeejatools.com

Drill bits are relatively common in our daily lives, and the most common one is probably the wood auger drill bit . After purchasing a drill, the most important thing is to polish the drill. In fact, after polishing, we still have a lot to pay attention to, let’s take a look at it together.
After the two blades are sharpened, pay attention to sharpening the tip of the drill bit with a larger diameter. After the two blades of the drill are sharpened, there will be a flat surface at the tip of the two blades, which affects the center positioning of the drill. It is necessary to chamfer the angle behind the blade to make the flat surface of the blade tip as small as possible. The method is to erect the drill bit, align it with the corner of the grinding wheel, and pour a small groove at the root behind the blade against the tip of the blade. This is also an important point for drill centering and cutting briskly. Note that when grinding the chamfer of the cutting edge, do not grind it to the main cutting edge. This will increase the rake angle of the main cutting edge and directly affect the drilling.
Of course, there is no fixed formula for grinding drill bits. It is necessary to accumulate experience in actual operation. Through comparison, observation, and trial and error, the drill bit will grind better. However, the HSS cobalt drill bit is the same. www.jeejatools.com

Wood drills are rod-shaped or spiral-shaped tools with a cutting edge at the end, which are used to process through holes or blind holes. The difference between the woodworking head and the woodworking end mill is that there is no edge on the side. In addition to the main cutting edge, the wood drill has a sharp countersunk edge to cut the wood fiber and make the side of the hole flatter. But the length of the wood drill bit is not enough in some places, so there is the emergence of the extra long wood drill bit .
The extra long wood drill bit has a large cutting capacity and is generally made of ordinary carbon steel, which is simple to manufacture, such as forging, stamping, grinding, etc.
The moving speed of the drill bit on the surface of the grinding wheel is 4~5m/min, and the thickness of the drill bit being ground is less than 0.15mm. Do not press the drill bit hard on the grinding wheel. The drill bit is fed by turning the screw 2. Grind the flank on one side and then grind the other side. To reduce the length of the chisel edge, the chisel edge can be ground by hand on the small diameter grinding wheel from both sides of the spiral groove. After sharpening the drill, use oilstone with a grain size of 200 to 400 for fine polishing.

The moving speed of the drill bit on the surface of the grinding wheel is 4~5m/min, and the thickness of the drill bit being ground is less than 0.15mm. Do not press the drill bit hard on the grinding wheel. The drill bit is fed by turning the screw 2. Grind the flank on one side and then grind the other side. To reduce the length of the chisel edge, the chisel edge can be ground by hand on the small diameter grinding wheel from both sides of the spiral groove. After sharpening the drill, use oilstone with a grain size of 200 to 400 for fine polishing.

For the Diamond cup grinding wheel , the most important thing is the cutting speed, so the choice of the carcass of the cutter head is particularly important.
Diamond cup grinding wheel is a kind of diamond tool, which is mainly suitable for the surface grinding of various refractory materials. The product adopts a specially designed tapered mounting hole structure, which is easy to install and unload. It has good processing flatness and grinding efficiency. It has the advantages of high and long life, which can be applied to all domestic and imported grinding equipment. Diamond cutter heads have different matrixes, different particle sizes, and different diamond concentrations; matrixes can be divided into hard, medium, soft, etc.; particle sizes are divided into coarse, medium, and fine; so their quality and use are different; When we choose a diamond grinding wheel, we can choose the right one according to our purpose; for example, when we are grinding hard ground, we should choose a soft matrix grinding wheel; if it is fairly soft ground, we can choose relatively speaking A relatively hard carcass.
And Tungsten carbide hole saws are also used as cutting tools, and the choice of blades is also selected according to the situation. www.jeejatools.com

The drill bit is relatively common in our daily life. It is a rotating tool with cutting ability at the tip. Then the drill bit needs to be polished regularly, and the extra long wood drill bit is naturally no exception. So how to sharpen the drill bit better?
The axis of the drill bit should be inclined at an angle of 60° with the surface of the grinding wheel. This angle is the front angle of the drill bit. The wrong angle at this time will directly affect the size of the top angle of the drill bit, the shape of the main cutting edge, and the bevel angle of the chisel edge. This refers to the positional relationship between the axis of the drill bit and the surface of the grinding wheel. It should be 60°. This angle is generally more accurate. Here we should pay attention to the relative horizontal position and angular position of the drill bit before sharpening. The two should be taken into consideration. Don’t neglect the angle to level the edge, or neglect to level the edge for the angle.
The above is the angle of the drill that we need to pay attention to when grinding the drill. TCT circular saw blades also need to be polished and maintained regularly, so they must be carefully maintained. www.jeejatools.com

Tungsten carbide hole saws can be cut quickly and accurately in metal, wood, drywall, or masonry. What is tungsten carbide?
Tungsten carbide uses metallic tungsten and carbon as raw materials. The tungsten trioxide WO3 is hydrogenated and reduced to obtain tungsten powder (average particle size 3-5μm). Then, the mixture of tungsten powder and carbon black in an equal molar ratio (dry-mixed with a ball mill for about 10 hours) is press-formed under a pressure of about 1t/cm2. Put the pressurized material block into a graphite pan or crucible and heat it to 1400～1700℃ (preferably 1550～1650) in a hydrogen stream (using pure hydrogen with a dew point of -35℃) using a graphite resistance furnace or an induction electric furnace ℃), carburizing will generate WC. The reaction starts from around the tungsten particles, because W2C is generated at the beginning of the reaction, and because the reaction is incomplete (mainly because the reaction temperature is low), unreacted W and intermediate W2C remain in addition to WC. Therefore, it must be heated to the above high temperature. The maximum temperature should be determined according to the particle size of raw tungsten.
Like tungsten carbide, the diamond in the Diamond cup grinding wheel is also a very hard mineral composed of carbon. www.jeejatools.com

In cutting tools, we are most concerned about cutting speed, so the quality of cutting tools is very critical. Therefore, many practitioners from cutting tools wholesale purchase products directly from the original manufacturers to ensure the quality of the products.
In the metal cutting process, the cutting part of the tool is carried out under the conditions of greater cutting force, higher cutting temperature, and severe friction. For threading tools and cutting tools, the choice of materials directly affects the service life of the tools, cutting efficiency, and the processing quality of parts.
We also know that there are many types of cutting tools, but according to the specific conditions of the workpiece material, tool geometric parameters, and cutting amount, the chip shape during turning can be roughly divided into three types, band-shaped chips, nodular chips, and crushing.
The most important thing for threading tools is the speed and convenience of threading. If the threading speed is very slow, then there is no value for threading tools. www.jeejatools.com
