Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is designed for creating smooth, countersunk holes in metal, particularly for aerospace and precision machining applications. Its six-flute design reduces chatter and produces a fine finish on steel, stainless steel, and non-ferrous materials.

What are the specifications of the KEO 919-000-805 countersink?

The KEO 919-000-805 is a 100° countersink with six flutes, a 1/4 in body diameter, and is made from cobalt steel. It is part of KEO's Smooth-Finish Six-Flute Countersinks line, designed for high-speed cutting and extended tool life in industrial settings.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-805 worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead times on this and other KEO cutting tools.

How to select the right KEO countersink for your application?

Select a KEO countersink based on material, hole angle, and finish requirements. For hard metals, choose cobalt steel like the 919-000-805. Match the 100° angle to standard fastener heads. Six-flute designs minimize vibration for smoother results on production runs.
