Description: M2AL HIGH SPEED STEEL MATERIAL 
M2AL High Speed Steel is a high alloy material with a hardness of up to 67.5 HRC, designed for increased endurance of the cutting edge and tool life. 

STEP HARDENED PROCESS 
This state of the art manufacturing process produces cutters with extremely hard tooth tips for increased cutter performance, while maintaining a softer body which is less susceptible to breakage than standard high speed steel cutters. 

MULTI-CUT GEOMETRY 
Provides smooth and fast cutting, with decreased chatter. This also increases the cutters ability to remove swarf away from the cut, and helps to enhance centering. 

FULLY GROUND WITH INTERNAL RELIEF 
This feature allows Holemaker cutters to produce reamed quality, burr-free holes, and also helps to reduce torque and horsepower requirements. 

UNIVERSAL SHANK 
19.05mm (3/4in) Universal Shank with 2 flat sections to suit most magnetic base drilling machines.
