What is a KEO 120° countersink used for?

How to select the right KEO countersink size?
Select a KEO countersink based on the screw head angle and body diameter needed. For flat-head screws, match the countersink angle (e.g., 120°) to the screw. The body diameter should be larger than the screw head. For the 917-000-101, the 1 1/4 in body suits medium-sized fasteners in metal or plastic.
