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.

Application

HSS twist drill bits are suitable for fast drilling of stainless steel, aluminum alloy, iron, plastic, copper, wood.

Note: It is forbidden to use on tiles, walls, concrete, stone, etc.!
