Frequently Asked Questions

What is the KEO 120° countersink used for?

The KEO 120° countersink is used to create a conical recess for flat-head screws in metalworking and machining applications. Its single-flute design provides fast, chatter-free cutting in steel, aluminum, and other materials, making it ideal for deburring and countersinking holes in industrial manufacturing.

What are the specifications of the KEO 919-000-165 countersink?

The KEO 919-000-165 is a 120° countersink with 1 flute and a 3/8 in body diameter, made from high-speed steel. It is designed for fast cutting and is suitable for use in drill presses and handheld tools. The KEO brand ensures precision and durability for repetitive industrial countersinking tasks.

Where to buy KEO countersinks worldwide?

You can source the KEO 919-000-165 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 genuine KEO tooling for manufacturing and maintenance operations.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the screw head angle (e.g., 120° for metric flat-head screws) and material. For steel or hard alloys, choose high-speed steel (HSS) like the 919-000-165. Match the body diameter to the hole size; a 3/8 in body suits smaller fasteners. Use cutting fluid for longer tool life.
