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?

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.
