Features

• Titanium Nitride (TiN) coating: The Titanium Nitride coating significantly increases the 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; Suitable for cutting a wide range of materials.
• M2AL High Speed Steel: 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 manufacturing 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 centring.
• 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 (¾") Universal Shank with 2 flat sections to suit most magnetic base drilling machines.
