These keyway end mills feature a TiN coating that helps protect them from wear, increases chip flow in softer materials, and allows the end mills to run at higher speeds than keyway end mills with a bright finish. High-speed steel end mills provide good wear resistance for general purpose milling applications. High-speed steel end mills have some flexibility and can absorb some shock and vibration in machining tasks.

Keyway end mills are used to make slots in parts so that key stock can be inserted into the slots when mating other components with the parts. Keyway end mills are typically undersized, which means they create an undersized slot. This ensures a snug, secure fit when the key stock is inserted into the slot. Each end mill has flutes on its cutting head that carry chips away from the workpiece to prevent damage to the end mill or workpiece. Keyway end mills are used on CNC or manual milling machines.
