Product Description

KEO General Purpose Three-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink is used to create a conical recess for flat-head screws in metalworking. Its 3-flute design reduces chatter for a smooth finish, and the AlTiN coating extends tool life on hardened steels and abrasive materials.

What are the specifications of the KEO 917-000-820 countersink?

The KEO 917-000-820 is a 100°, 3-flute countersink with a 3/4 in body diameter. It features AlTiN-coated carbide construction for heat resistance and durability. This general-purpose tool is designed for precision chamfering and deburring in industrial machining.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 917-000-820 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. Contact us for pricing and lead time on this AlTiN-coated carbide tool.

How to select the right KEO countersink for your application?

Select a KEO countersink based on screw head angle (e.g., 100° for metric flat-head screws), material hardness (AlTiN coating for steels), and flute count (3-flute for reduced vibration). Match body diameter to hole size. For guidance, consult 3G Electric's technical team.
