Frequently Asked Questions

What is the KEO 100° countersink used for?

The KEO 100° countersink is used for creating smooth, chamfered holes in metal, particularly for aerospace and automotive applications. Its six-flute design reduces chatter and produces a fine finish on steel, stainless steel, and aluminum. It is ideal for countersinking screw heads or deburring edges in precision machining.

What are the specifications of the KEO 919-000-817 countersink?

The KEO 919-000-817 is a 100° countersink with six flutes, a 5/8 in body diameter, and is made from cobalt steel. It is designed for smooth-finish applications and is suitable for use on hard metals. The manufacturer part number is 919-000-817, and it is produced by KEO.

Where to buy the KEO 919-000-817 countersink worldwide?

You can source the KEO 919-000-817 countersink through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations. Contact us for availability and lead times; we supply this KEO countersink to procurement teams and engineers globally.

How to select the right KEO countersink for your application?

To select the right KEO countersink, match the body diameter (e.g., 5/8 in) to your hole size and choose the angle (100°) for standard flat-head screws. For hard materials like stainless steel, opt for cobalt steel flutes. The six-flute design minimizes vibration, ensuring a smooth finish. Always verify the shank fits your tool holder.
