Product Description

KEO Fast-Cutting Single-Flute Countersinks.

Frequently Asked Questions

What is a KEO 100° countersink used for?

A KEO 100° countersink creates a conical recess for flat-head screws or rivets in metal, plastic, or wood. The single-flute design provides fast, chatter-free cutting. It is commonly used in machining, fabrication, and assembly operations across industrial departments.

What are the specifications of the KEO 919-000-253 countersink?

The KEO 919-000-253 is a 100° countersink with a single flute and a 5/8 in body diameter. It is made from high-speed steel (HSS) for durability. The 100° angle is designed for specific flat-head fasteners. This tool is suitable for general-purpose deburring and countersinking.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 919-000-253 to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial solutions provider, we source genuine KEO tooling and support your procurement needs across 14 departments.

How to select the right KEO countersink for your application?

Select a KEO countersink based on the fastener head angle (e.g., 100° for specific flat-head screws), material type (HSS for general use), and body diameter matching the screw head size. Single-flute designs offer fast cutting; multi-flute options provide smoother finishes. Consult your fastener specifications for the correct angle.
