KEO 82° General Purpose Three-Flute Countersink

A KEO 82° countersink with three flutes is used to create a conical recess for flat-head screws in metal or plastic. The 82° angle matches standard flat-head fastener angles, and the AlTiN coating on high-speed steel extends tool life in abrasive materials.

The KEO 917-000-430 is an 82° general-purpose three-flute countersink with a 1/4 in body diameter. It is made from AlTiN-coated high-speed steel. The three-flute design reduces chatter and provides a smooth finish. It is suitable for deburring and countersinking in ferrous and non-ferrous materials.

3G Electric supplies KEO countersinks like the 917-000-430 to customers worldwide. We handle full logistics, customs clearance, and delivery to your site. As a global industrial solutions provider, we source genuine KEO tooling and support your procurement needs across multiple departments.

Select a KEO countersink based on the fastener head angle—82° for standard flat-head screws. Match the body diameter to the screw head size. For harder materials, choose AlTiN-coated high-speed steel for heat resistance. Three-flute designs minimize vibration and are ideal for general-purpose use in machining centers.
