Carbide Straight-Tooth Keyseat End Mills
Keyseat Cut Style
Made of solid carbide, these cutters are harder, stronger, and more wear resistant than high-speed steel and cobalt steel for the longest life and best finish on hard material. Their extreme hardness means they are brittle, so a highly rigid setup, such as a CNC machine, is necessary to prevent the end mill from breaking. Use them to mill precise notches in rotary shafts to fit machine keys. They can also be used for slot milling.

High-Speed Steel Staggered-Tooth Keyseat End Mills
Keyseat Cut Style
Use these end mills for general purpose keyseat cutting in a wide range of material, including aluminum, iron, and steel. An alternating right- and left-hand tooth style allows them to remove more material at high speeds than straight-tooth keyseat cutters. They mill precise notches in rotary shafts to fit machine keys and can also be used for slot milling.

Carbide Staggered-Tooth Keyseat End Mills
Keyseat Cut Style
Made of solid carbide, these keyseat cutters are harder, stronger, and more wear resistant than high-speed steel for the longest life and best finish on hard material. They have an alternating right- and left-hand tooth style for removing more material at high speeds than straight-tooth keyseat cutters. They mill precise notches in rotary shafts to fit machine keys and can also be used for slot milling.
