255 Series End Mills

Geometry Specifications:

Axial: Positive
Radial: Negative

255 Series have increased face clearance from standard XR series for increased ramp capability, and they have a multi-purpose positive/negative geometry which optimizes horsepower for full utilization. The diameter is measured over the maximum diameter for profile mold programming.
