Frequently Asked Questions

What is the KEO 60° countersink used for?

The KEO 60° countersink is used for deburring and countersinking holes in metal, creating a smooth, chamfered edge for fastener seating. Its six-flute design reduces chatter and delivers a fine finish on steel, stainless steel, and other alloys. Common in aerospace, automotive, and general machining applications.

What are the specifications of the KEO 60° countersink?

The KEO countersink has a 60° included angle, six flutes, and a 1 1/4 in body diameter. It is made from cobalt high-speed steel for heat resistance and durability. The manufacturer part number is 919-000-717. This tool is designed for smooth-finish countersinking in hard materials.

Where to buy the KEO 60° countersink worldwide?

You can source the KEO 60° 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 time. 3G Electric supplies this KEO cobalt countersink to procurement teams internationally.

How to select the right KEO countersink for your application?

Select the KEO countersink based on material hardness and hole size. For hard metals like stainless steel, choose cobalt steel for heat resistance. The 60° angle suits standard fastener heads. Match the body diameter to your hole size. For best results, use proper cutting fluid and moderate speeds to extend tool life.
