KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is the KEO 90° countersink used for?

The KEO 90° countersink is used to create a conical recess for flat-head screws in metalworking and woodworking. Its single-flute design provides fast, chatter-free cutting in materials like steel, aluminum, and plastics. Ideal for deburring holes and preparing surfaces for flush fasteners in industrial fabrication.

What are the specifications of the KEO countersink 919-000-959?

The KEO countersink model 919-000-959 has a 90° included angle, 1 flute, and a 5/8 in body diameter. It is made from carbide for durability and precision. The manufacturer part number is 919-000-959, and it is designed for fast-cutting single-flute countersinking operations.

Where to buy the KEO countersink 919-000-959 worldwide?

You can source the KEO countersink 919-000-959 through 3G Electric, a global industrial equipment distributor. We handle full logistics, customs clearance, and delivery to worldwide destinations.
