KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used for deburring and countersinking holes in metal, especially in aerospace and automotive applications. Its single-flute design provides fast, chatter-free cutting in steel, stainless steel, and other alloys. The 100° angle is common for flat-head screws in precision assemblies.

What are the specifications of the KEO 100° countersink?

This KEO countersink has a 100° included angle, 1 flute, 1 3/4 in body diameter, and 3/4 in shank diameter. It is made from cobalt steel (MPN 919-000-641). The single-flute design enables aggressive material removal while maintaining a smooth finish on ferrous and non-ferrous metals.

Where to buy the KEO 100° countersink worldwide?

Contact us for pricing and lead time. We source genuine KEO tooling for manufacturing and maintenance operations across all regions.

How to select the correct KEO countersink for your application?

Select the KEO countersink based on screw head angle (100° for flat-head screws), material hardness (cobalt for tough alloys), and hole size. Match the body diameter to the countersink depth required. For deep holes, use a longer flute length. Always verify shank diameter fits your tool holder.
