Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its zero-flute design minimizes vibration and chatter, making it ideal for precision countersinking in steel, stainless steel, and other hard materials.

What are the specifications of the KEO 100° countersink?

The KEO 100° countersink has a 3/4 in body diameter, a 100° included angle, zero flutes, and a TiN-coated cobalt construction. The manufacturer part number is 919-000-245. This anti-vibration design reduces chatter and extends tool life in demanding industrial applications.

Where to buy KEO countersinks worldwide?

You can source KEO countersinks worldwide through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to your facility. Contact us for availability and lead time on the KEO 100° countersink model 919-000-245.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (typically 82° or 100°), material hardness, and desired finish. For hard materials like stainless steel, choose a TiN-coated cobalt version like the 100° model 919-000-245. The zero-flute design reduces vibration for cleaner results.
