Imported cemented carbide tungsten steel drill bit for PCB circuit board
Material: The blade is made of imported tungsten carbide and the handle is made of white steel.
Note: The drill bit is very thin and easy to break, so the operation should be standardized.
Shank diameter: 3.175MM, we can use JT0 drill clips!
Processing scope: PCB, SMT, CNC, mold, sculpture, plastic, copper, stainless steel and other hardware processing.
Color : Random
Product features:
① Large chip removal space of the drill bit: small chip removal resistance, smooth chip removal, small drilling heat, reducing drilling pollution;
② Superior cutting edge sharpness: thanks to the adoption of nanotechnology and advanced grinding technology, the cutting edge of the drill bit is sharper than before, which can reduce the cutting force, reduce the rate of broken drilling, and improve the quality of the hole wall;
③ Cutter design based on customer application: there are many kinds of drills, which can meet different application requirements. All parameters of the drill bit, such as drill core thickness and drill core taper, have been carefully designed with obvious effect;
④ The cutting edge is strictly symmetrical, which is conducive to efficient cutting and avoids drilling offset.
Product introduction:
The ring on the bit body has different colors due to different batches. Red, purple, blue and yellow are possible.
The drill bit is very sharp. Use it carefully to avoid scratching your hands
Pay attention to the concentricity of rotation during use, especially when drilling the barrel ball. Because of the long drilling distance, too large deviation from the concentricity during drilling may easily cause broken needles.
Note:
Do not clamp it on the electric hand drill for high-speed rotary drilling, so the amber will collapse.
When drilling, pay attention to cleaning the amber powder drilled at any time while rotating.
Hold the tail of the drill bit by hand and slowly rotate it for drilling. When it is about to be drilled, especially reduce the speed and strength.
Processing range: applicable to PCB NC drilling
Statement: This drill is made of cemented carbide tungsten steel and is expensive. The material itself is fragile and must be handled with care during use. It is a special accessory for precision equipment such as engraving machines and high-speed drilling machines. Handheld electric drills and electric grinders are unstable and easy to break when drilling!
For example, the amber drilling method:
Step 1: Put the drilling drill on the hand drill and tighten it with a wrench. Remember to tighten the drill chuck several times with the key to prevent the drill bit from loosening during drilling and causing the drill bit to break!
Step 2: The hole shall be drilled vertically with proper force (not too hard). Slowly twist the hole by hand (twist it in one direction). The needle shall not be broken by force or prying!
When drilling, pay attention to cleaning the amber powder at any time while rotating. Hold the end of the hand drill and slowly rotate the hole. Remember that when the hole is about to be drilled, especially reduce the speed and strength. If you feel the needle is tight when rotating, please immediately withdraw the needle and clean the hole powder.
Step 3: After drilling, remember that the drill bit is very sharp. Use and store it carefully to avoid scratching your hands.
Again, pay attention to the concentricity of rotation during use, especially when drilling the barrel ball. Because of the long drilling distance, too much deviation from the concentricity during drilling may easily lead to broken needles.
