Product Description

The raw material of twist drill bit is high-speed steel, and high-speed steel (HSS) is a kind of tool steel. M2(6542)HSS twist drills are harder and more heat resistant than high carbon steel drill bits. High-speed steel bits have higher cutting speeds than high-carbon steel bits.
M2 HSS twist drill bits are widely used in various metals such as stainless steel, aluminum alloy, copper, etc., and can also be used for drilling in wood, PVC and other materials.

Product Details

118° and 135° split points

The 118° point angle is mainly used for softer materials such as mild steel and cast iron.
The 135° split point is used for cutting hard steel, especially for deep holes that are more than 4 times the diameter of the drill bit. Using the 135° split point, cutting harder materials produces thicker chips, minimizing work hardening of the cavity.

Spiral fluted shank

Fully ground body construction. High flow spiral design for the fastest removal speed and for thick material

Straight shank

Straight shank for standard chuck,
less "walking" or "wandering."
The end of the shank is chamfered
to allow an easy and firm grip.
Special SST heat treatment of bronze
and surface.

HSS Twist Drill Bits RPM

NOTE:Bigger diameters ,slower rotation speed .
- Cobalt drill bits require slow RPM when drilling metals. The suggested RPM is only for your reference. It may vary from different materials. You can start from a lower RPM and adjust it higher slowly. Once the bit can get into the work piece. the adjustment should be stopped. Punching more than 2mm add coolant to continue punching, is to extend the life of the drill bit.
