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, anti-vibration design reduces chatter and improves surface finish on materials like steel and stainless steel, making it ideal for precision deburring and countersinking in industrial manufacturing.

What are the specifications of the KEO 919-000-241 countersink?

The KEO 919-000-241 is a 100° countersink with a 1/2 in body diameter and a 5/16 in shank. It has zero flutes, is made of cobalt steel with a TiN coating, and is designed for anti-vibration performance. This tool is suitable for creating precise countersinks in hard metals and is supplied by 3G Electric.

Where to buy the KEO 919-000-241 countersink worldwide?

You can source the KEO 919-000-241 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead time; we provide this KEO tool as part of our extensive sourcing network.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 100° for metric flat-head screws), material hardness, and desired finish. For hard metals, choose a TiN-coated cobalt variant like the 919-000-241 to reduce wear. Match the body diameter to the hole size and ensure the shank fits your tool holder. 3G Electric can advise on specifications.
