KEO Countersink: 120°, 3 Flute, 3/8 in Body Dia

A KEO 120° countersink with 3 flutes and AlTiN coated cobalt is used to create a conical recess for flat-head screws in metalworking. It is ideal for deburring holes and preparing surfaces in machining, fabrication, and maintenance applications across industrial departments.

The KEO 917-000-850 is a general-purpose three-flute countersink with a 120° included angle, 3/8 in body diameter, and AlTiN coated cobalt construction. It is designed for use in CNC and manual machines to produce clean, accurate chamfers in ferrous and non-ferrous materials.

3G Electric supplies KEO countersinks worldwide, handling full logistics and customs clearance for global delivery. As a sourcing partner across 14 industrial departments, we provide genuine KEO cutting tools like the 917-000-850 to meet your machining requirements anywhere.

Select a KEO countersink based on material, hole size, and desired chamfer angle. For flat-head screws, match the countersink angle to the screw head (e.g., 120° for metric). The 3-flute design reduces chatter, while AlTiN coating extends tool life in abrasive materials.
