Product Description

KEO Smooth-Finish Six-Flute Countersinks.

Frequently Asked Questions

What is a KEO 120° 6-flute countersink used for?

This KEO high-speed steel countersink creates smooth, burr-free 120° chamfers on drilled holes. It is commonly used in metalworking, machining, and fabrication to prepare holes for flathead screws or deburr edges. The six-flute design reduces chatter and delivers a fine finish.

What are the specifications of the KEO 919-000-504 countersink?

The KEO 919-000-504 is a 120° countersink with six flutes, a 1-inch body diameter, and is made from high-speed steel. It is designed for smooth-finish applications and is part of KEO's six-flute countersink series. The SKU is 3G-OTH-188028.

Where to buy KEO countersinks worldwide?
