Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 82° countersink used for?

This KEO single-flute countersink creates 82° chamfered holes in metal, plastic, or wood. It is commonly used in machining and fabrication to deburr drilled holes or prepare countersunk screw seats. The carbide tip provides long life in production environments.

What are the specifications of the KEO 919-000-939 countersink?

The KEO 919-000-939 is an 82° countersink with a single flute and a 5/8 in body diameter. It is made of carbide for durability. The 1-flute design enables fast chip evacuation and clean cuts in ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-939 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this carbide single-flute tool.

How to select the right KEO countersink for your job?

Match the countersink angle (82° for standard flat-head screws) and body diameter to your hole size. Single-flute designs like this KEO model cut fast and clear chips well. For harder materials, carbide is preferred over HSS for longer tool life.
