KEO 82° Single-Flute Countersink, 1/2 in Body Dia, AlTiN Coated Carbide

The KEO 82° single-flute countersink is designed for deburring and countersinking holes in metal, plastic, and composite materials. Its 82° included angle matches standard flat-head screw angles, making it ideal for aerospace, automotive, and general machining applications where a smooth, chamfered hole entry is required.

The KEO 919-002-322 is a 1-flute countersink with an 82° included angle and a 1/2 in body diameter. It features an AlTiN (aluminum titanium nitride) coating on carbide substrate for extended tool life and heat resistance. This fast-cutting design is optimized for high-speed steel or carbide toolholders in CNC and manual machines.

Choose the KEO countersink based on material and screw angle. For standard flat-head screws, an 82° angle is typical. Single-flute designs like the 919-002-322 provide fast chip evacuation in softer metals. AlTiN coating improves wear resistance in abrasive materials. Match body diameter to your hole size and toolholder capacity for optimal results.
