Product Description

The KEO Countersink: 110° is a fast-cutting single-flute countersink with a TiN coated cobalt body, featuring a 1 1/2 in body diameter and a 3/4 in shank (MPN 55457-TiN). This KEO tool is designed for efficient deburring and chamfering operations.

Frequently Asked Questions

What is a KEO 110° single-flute countersink used for?

A KEO 110° single-flute countersink creates a conical recess for flathead screws in metalworking. The 110° angle suits metric and aerospace fasteners. Its TiN-coated cobalt body resists heat and wear, making it ideal for hardened steels and stainless steel in machining and fabrication.

What are the specifications of the KEO 55457-TiN countersink?

The KEO 55457-TiN is a 110° single-flute countersink with a 1 1/2 in body diameter and a 3/4 in shank. It is made from TiN-coated cobalt for durability. This fast-cutting design reduces chatter and produces clean, burr-free holes in ferrous materials.

Where to buy KEO countersinks worldwide?

3G Electric supplies KEO countersinks like the 55457-TiN to customers worldwide. We handle full logistics, customs clearance, and delivery to your facility. As a global industrial sourcing partner, we provide genuine KEO cutting tools without requiring local distributor access.

How to select the right countersink for a job?

Match the countersink angle to your fastener head (82° for inch, 90° for common, 110° for metric/aircraft). Choose a single flute for fast stock removal or multiple flutes for finer finish. TiN coating extends tool life in abrasive materials like stainless steel.
