KEO 100° Single-Flute Countersink

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design and AlTiN coating on high-speed steel provide fast cutting and extended tool life in ferrous and non-ferrous materials.

The KEO 919-002-858 is a 100° countersink with one flute and a 3/8 in body diameter. It is made from AlTiN-coated high-speed steel for wear resistance. The manufacturer part number is 919-002-858, and it is designed for fast-cutting single-flute countersinking operations.

Select a KEO countersink based on the screw head angle (e.g., 100° for metric flat-head screws) and material. For harder steels, choose AlTiN-coated high-speed steel like the 919-002-858. Match the body diameter to the screw head size and ensure the flute count suits your cutting speed needs.
