4" Cutter Diam, Arbor Connection, Convex Radius Cutter

Item #: 20086930
Brand: Keo
Model #: 921-000-048

Features and Benefits

High speed steel (HSS) provides good wear resistance. It is commonly used for general purpose applications for both ferrous and nonferrous materials.

Titanium nitride (TiN) is a multi-purpose coating which increases chip flow in softer materials. The heat and hardness resistance allows the tool to run at higher speeds than uncoated tools.
