High Speed Steel – Center Cutting

30° Helix Angle

4-Flute end mills with a greater core thickness offer increased tool strength and reduced tool deflection. 4-Flutes also reduce chip load per tooth for the milling of tougher materials, greater wear resistance and improved surface finish.

Recommended for easy-to-machine materials including low alloy steels, non-ferrous materials and cast iron. Ideal for periphery cutting, slotting, and pocketing

Center Cutting end allows for plunge cutting into solid material.

** When plunging feed rates usually need to be dropped to a 1/3 to a ½ of normal feedrates. **
