Product Details

These keyway end mills have a bright finish that provides a smooth, polished surface. They are made from high-speed steel, which provides 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.
