Keo 919-001-022 Countersink 5/8 in 82 Degree 6 Flute Carbide

Product Description

The KEO 919-001-022 is a single-end solid carbide countersink designed for precision chamfering, countersinking, and deburring operations in metalworking and machining environments. It features a 5/8-inch head diameter, an 82-degree included angle, and 6 flutes that support clean, accurate material removal with reduced chatter. The solid carbide construction provides the hardness and wear resistance required for production use on ferrous and non-ferrous materials. The 3/8-inch shank diameter fits standard drill chucks and collet holders, making it straightforward to mount in most machining setups. Machinists and tool-and-die professionals are the primary users of this tool.

This countersink is suited for chamfering drilled holes, preparing fastener seats, and deburring edges in shop and production environments. The 82-degree included angle accommodates common flat-head fastener specifications used in aerospace, automotive, and general manufacturing applications. With a 2.75-inch overall length and a 5/8-inch maximum cutting diameter, it handles typical countersinking tasks on workpieces held in milling machines, drill presses, or CNC machining centers.

Key Features

• Suitable for chamfering, countersinking, and deburring in a single tool

Compatibility

Designed as an OEM-style single-end countersink compatible with standard 3/8-inch collet holders, drill chucks, and tool holders used in drill presses, milling machines, and CNC machining centers.

Installation Notes

Installation and use should be performed by qualified machinists or tooling professionals. Secure the 3/8-inch shank firmly in a collet or chuck before operation and verify runout is within acceptable limits for the application. Power down and de-energize the machine before changing tooling. Do not exceed the recommended spindle speeds for carbide tooling in the specific workpiece material.
