KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 120° countersink used for?

A KEO 120° countersink creates a conical recess for flat-head screws in metalworking. Its single-flute design and AlTiN-coated high-speed steel deliver fast, clean cuts in steel and stainless steel, reducing chatter and improving finish.

What are the specifications of the KEO 919-002-856 countersink?

The KEO 919-002-856 is a 120° single-flute countersink with a 3/8 in body diameter, made from AlTiN-coated high-speed steel. It is designed for fast cutting in hard materials and is part of KEO's precision tooling line.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks worldwide, handling full logistics and customs clearance. As a global industrial sourcing partner, we provide genuine KEO cutting tools like the 919-002-856 to customers across machining and fabrication industries.

How to select the right KEO countersink for your application?

Match the countersink angle (e.g., 120°) to your screw head type. Choose flute count based on material: single-flute for fast chip removal in steel. AlTiN coating extends tool life in abrasive materials. Consult KEO's technical data for RPM and feed rates.
