- It is extremely heat resistant and used for high speed applications on cast iron, nonferrous materials, plastics and other tough-to-machine materials
- Plain cutting edge
- +0.003/-0.000 in D1, -.0001/-.0005 in D2 tolerances
- Used to produce a center hole on material
- Spiral flutes are constructed of a higher flute angle to remove chips easier
- Used in lathe or cylindrical-grinder work to create conical holes
- It increases chip flow in softer materials such as aluminum, wood and plastic
- External Coolant
Application: Aerospace, Medical, Power Generation, Automotive, General Engineering, Mold and Die, Casting and Foundries
