KEO Countersink: 110°, 3 Flute, 1 1/4 in Body Dia

A KEO 110° countersink with three flutes is used to create a conical recess for flat-head screws or to deburr holes in metal. The 110° angle is common in aerospace and sheet-metal work. The TiN-coated cobalt construction provides heat resistance and extends tool life in ferrous materials.

The KEO 55346-TiN is a general-purpose three-flute countersink with a 110° included angle and a 1 1/4 in body diameter. It is made from cobalt steel with a titanium nitride (TiN) coating for wear resistance. This tool is designed for use in drill presses or handheld drills.

3G Electric supplies KEO countersinks like the 55346-TiN to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine KEO tooling and support procurement across 14 departments including machining and tooling.

Select a KEO countersink based on the screw head angle (e.g., 110° for flat-head screws), material hardness (TiN-coated cobalt for steel), and flute count (three flutes for general-purpose deburring). Match the body diameter to the screw head size. For hard alloys, consider a coated tool for longer life.
