PCB circuit board drill bit carbide tungsten steel drill bit
The blade is made of hard tungsten alloy, and the handle is made of white steel.

Note: The drill bit is very thin and easy to break, and the operation should be standardized.

Shank diameter: 3.175MM, JT0 drill clips in can be used!

Processing range: PCB, SMT, CNC, mold, engraving, plastic, copper, stainless steel and other hardware processing.

Features:
①Large chip removal space of the drill bit: small chip removal resistance, smooth chip removal, small drilling heat generation, and reduced drilling pollution;
②Extraordinary cutting edge sharpness: Due to the use 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 breakage rate, and improve the quality of the hole wall;
③Tool design based on customer application: a variety of drill bits can be used to meet different application needs. All parameters of the drill bit, such as core thickness, core taper, etc., are carefully designed and have obvious effects;
④The cutting edge is strictly symmetrical: it is conducive to efficient cutting and avoids drilling offset.

The ring set on the drill bit is different in color because of different batches, red, purple, blue, and yellow are all possible.

The drill bit is very sharp, be careful not to scratch your hands
Pay attention to the concentricity of rotation during use, especially when drilling the barrel beads, because the drilling distance is long, and the deviation from the concentricity when drilling is too large, which will easily cause the needle to break.

Precautions: It must not be clamped on a hand drill to rotate at a high speed to make holes, so that the amber will collapse.
When drilling, pay attention to cleaning the amber powder that is drilled out at any time while rotating.
Grab the end of the drill bit with your hand and rotate it slowly to drill the hole, especially when you are about to get through, reduce the speed and strength.
If the needle feels tight when it is rotated, please withdraw the needle immediately, clear the hole and re-enter the powder.

Statement: This drill bit is a tungsten carbide drill bit. The material itself is brittle and must be handled with care. It is a special accessory for precision equipment such as engraving machines and high-speed drilling machines. Hand-held electric drills and electric grinders are unstable and easy to drill. break!
