What is a KEO 100° single-flute countersink used for?

This KEO countersink creates 100° chamfered holes in metal, ideal for deburring and preparing fastener seats in machining, fabrication, and maintenance. Its single-flute design cuts fast with reduced chatter, and the TiAlN coating extends tool life on hard materials.

What are the specifications of the KEO 55738-TiALN countersink?

The KEO 55738-TiALN is a 100° single-flute countersink with a 1 1/4 in body diameter and 1 1/4 in shank. It is made from TiAlN coated carbide for heat resistance and durability. The 1-flute geometry enables aggressive chip evacuation in production environments.
