Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is designed for creating chamfered holes in metal, typically for flat-head screws. Its single-flute design provides fast, chatter-free cutting in steel, stainless steel, and other alloys. The TiN coating reduces friction and extends tool life.

What are the specifications of the KEO 919-000-638 countersink?

This KEO countersink has a 100° included angle, 1 flute, and a 1 1/4 in body diameter. It is made from cobalt steel with a TiN coating for heat resistance. The manufacturer part number is 919-000-638. It is suitable for high-speed machining of hard materials.

Where to buy the KEO 919-000-638 countersink worldwide?

3G Electric supplies the KEO 919-000-638 countersink to customers worldwide. We handle full logistics, customs clearance, and delivery to your location. Contact us for availability and lead time. As a global industrial distributor, we source and deliver this tool to any country.

How to select the correct KEO countersink for my application?

Select a KEO countersink based on the screw head angle (e.g., 100° for metric flat-head screws) and material. For hard metals, choose TiN-coated cobalt steel like the 919-000-638. Match the body diameter to the hole size. Single-flute designs work best for fast, clean cuts in production work.
