• Solid carbide provides better rigidity than high speed steel. It is extremely heat resistant and used for high speed applications on cast iron, non-ferrous materials, plastics and other tough-to-machine materials
• Titanium nitride (TiN) is a multi-purpose coating that increases chip flow in softer materials. the heat and hardness resistance allows the tool to run at higher speeds than uncoated tools
• Titanium aluminum nitride (TiAlN) has a higher hardness than TiN and TiCN. It is extremely heat resistant and commonly used for high speed applications on stainless steels, nickel and titanium alloys
• Spiral flutes are constructed with a higher flute angle to remove chips more easily
• H7 tolerance on cut/shank diameter
• 29 mm L Shank
• External coolant
