Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink is used to create a conical recess in a workpiece, typically for flat-head screws or rivets with a 100° included angle. It is common in metalworking, aerospace, and general fabrication where a flush fastener finish is required.

What are the specifications of the KEO 917-000-115 countersink?

The KEO 917-000-115 is a 100°, three-flute countersink made from high speed steel. It has a 1 1/2 in body diameter and a 3/4 in shank. The three-flute design reduces chatter and provides a smoother finish compared to single-flute tools.

How to select the right countersink for a 100° flat-head screw?

Match the countersink angle exactly to the screw head angle—100° for this KEO tool. Choose a three-flute design for reduced vibration on harder materials. Ensure the body diameter exceeds the screw head size, and the shank fits your drill chuck or collet.
