KEO 90° Six-Flute Countersink, 1 1/4 in Body Dia, AlTiN Coated HSS

The KEO 6-flute countersink is used for creating smooth, burr-free 90° chamfers on drilled holes in metal, plastic, and wood. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and countersinking in automotive, aerospace, and general manufacturing applications.

The KEO countersink model 919-002-721 has a 90° included angle, 6 flutes, a 1 1/4 in body diameter, and is made from AlTiN coated high speed steel. The AlTiN coating enhances wear resistance and allows for higher cutting speeds on ferrous and non-ferrous materials.
