- No-margin design ensures less friction and heat generation, thus increasing tool life.
- Internal coolant supply system
- High versatility and the ability to machine a wide range of materials without the need for setup.
- Excellent centering properties, reduced axial forces.
- High quality machined holes, roundness, and cylindricity regardless of the material.
- Carbide grade with double TiN and TiAlN coating
