M2AL HIGH SPEED STEEL MATERIAL 
M2AL High Speed Steel is a high alloy material with a hardness of up to 67.5 HRC. 

TITANIUM NITRIDE COATING 
The Titanium Nitride coating increases tool life by providing the following benefits: 
• Increased surface hardness to 85HRC 
• Ceramic surface, reducing friction by up to 30% 
• Especially resistant to cold welding 

STEP HARDENED PROCESS 
Cutter is manufactured with extremely hard tooth tips for increased cutter performance, while maintaining a softer body which is less susceptible to breakage. 

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.
