Keo 919-000-941 Countersink 3/4 in 82 Degree Solid Carbide

Product Description

The KEO 919-000-941 is a single-flute solid carbide countersink designed for chamfering, countersinking, and deburring operations in metalworking and fabrication environments. With a 3/4 inch head diameter, an 82-degree included angle, and a 3/8 inch shank diameter, this tool fits standard drill chucks and collet holders used in machining setups. The solid carbide construction delivers hardness and wear resistance suited for cutting ferrous and non-ferrous materials. At 2.75 inches overall length and weighing 0.18 pounds, it is compact enough for use in drill presses, CNC machines, and hand-held power tools where access and precision are priorities.

This countersink is appropriate for shops and tradespeople performing finish work on metal components that require clean, accurate chamfers or countersunk holes for flat-head fasteners. The 82-degree included angle is a standard geometry commonly specified in aerospace and general manufacturing applications. Typical use cases include deburring drilled holes, preparing fastener seats, and breaking edges on steel, aluminum, and similar workpiece materials. The single-flute design allows for smooth cutting action and easy chip evacuation during hand-feed and machine-feed operations.

Key Features

• Solid carbide construction for extended tool life and hardness in demanding cutting applications
• 82-degree included angle matches standard flat-head fastener countersink geometry
• 3/4 inch maximum cutting diameter accommodates a wide range of hole sizes
• Single-flute end type promotes smooth chip evacuation and clean chamfer finish
• 3/8 inch shank diameter fits common drill chucks and collet holders
• Suitable for chamfering, countersinking, and deburring in a single tool

Compatibility

Designed as a standard single-flute solid carbide countersink compatible with drill presses, CNC machining centers, and hand-held power tools accepting a 3/8 inch shank.

Installation Notes

Installation and use should be performed by a qualified machinist or tool operator familiar with cutting tool safety practices. Secure the shank firmly in the chuck or collet before operation and confirm the workpiece is clamped or fixtured to prevent movement. Power down and de-energize the machine before changing or inspecting the tool. Do not exceed the recommended feed and speed parameters for the workpiece material and machine type.
