Product Description

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 steel, aluminum, and plastics, making it ideal for deburring holes and preparing surfaces for flush fasteners in industrial fabrication.

What are the specifications of the KEO 90° countersink?

This KEO countersink has a 90° included angle, 1 flute, 1 3/4 in body diameter, and 3/4 in shank diameter. It is made of high-speed steel (HSS) for durability. The manufacturer part number is 919-000-183. It is designed for use in drill presses or handheld drills for precision countersinking.

Where to buy the KEO 90° countersink worldwide?

You can source the KEO 90° 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 provide reliable sourcing for KEO cutting tools.

How to select the correct KEO countersink for your application?

Select a KEO countersink based on the screw head angle (typically 90° for flat-head screws), material type, and hole size. Match the body diameter to the screw head size and ensure the shank fits your tool holder. For hard materials, choose HSS; for softer materials, consider carbide. Always test on scrap material first.
