Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used for deburring and countersinking holes in metal, plastic, and wood. Its 120° included angle suits flat-head screws and precision chamfering. The three-flute design provides smooth cutting and reduced chatter, making it ideal for general-purpose machining in industrial fabrication and maintenance.

What are the specifications of the KEO 917-000-259 countersink?

The KEO 917-000-259 is a 120° countersink with three flutes and a 3/8 in body diameter. It is made from cobalt steel for durability and heat resistance. This general-purpose tool is designed for use in drill presses and handheld drills, offering reliable performance in metalworking applications.

Where to buy the KEO 917-000-259 countersink worldwide?

You can source the KEO 917-000-259 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; we supply this KEO tool to procurement teams and engineers internationally.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the required angle (e.g., 120° for flat-head screws), material (cobalt for hard metals), and body diameter matching your hole size. For general deburring, a three-flute design reduces vibration. Always match the tool to your workpiece hardness and machine speed for optimal results.
