Frequently Asked Questions

What is a KEO 60° 6-flute countersink used for?

This KEO countersink creates smooth, burr-free 60° chamfers on drilled holes in metal, plastic, and wood. Its six-flute design reduces chatter and vibration, making it ideal for precision deburring and countersinking in machining, fabrication, and assembly applications.

What are the specifications of the KEO 919-000-316 countersink?

The KEO 919-000-316 is a 60° countersink with a 3/4 in body diameter, 6 flutes, and TiN-coated high-speed steel construction. The TiN coating increases hardness and lubricity for longer tool life when cutting ferrous and non-ferrous materials.

Where to buy KEO countersinks worldwide?

How to select the right KEO countersink for my application?

Choose a countersink angle matching your fastener head (e.g., 60° for standard machine screws). Match body diameter to hole size. For hard materials like steel, select TiN-coated HSS for longer life. For softer materials, uncoated HSS may suffice. KEO offers various flute counts for finish quality.
