Keo 907-000-173 Combo Drill Countersink Size 7 Hss

Product Description

The KEO 907-000-173 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, it delivers consistent performance in metal fabrication and machining applications. The tool features a 1/4-inch drill point diameter, a 5/8-inch body diameter, and a 6-inch overall length, making it well-suited for long-reach countersinking tasks. The 118-degree drill point angle and 60-degree included angle are standard geometry for general-purpose work in ferrous and non-ferrous materials.

This combo drill countersink is used in machine shops, manufacturing facilities, and on-site fabrication work where deburring, chamfering, and pilot drilling need to be completed efficiently. Its right-hand cut and plain cutting edge style make it compatible with standard drill press setups and CNC machining centers. The double end type extends tool life by providing two usable ends, reducing downtime for tool changes in high-volume production environments.

Key Features

• High-speed steel construction for durability across ferrous and non-ferrous materials
• Bright, uncoated finish suitable for general-purpose countersinking applications
• Double-end design extends usable tool life
• 118-degree drill point angle with 60-degree included angle for standard countersink geometry
• 6-inch overall length classified as a long-length tool for extended reach applications
• Right-hand cut with plain cutting edge for use in conventional drill press and CNC setups

Compatibility

Designed as a general-purpose combination drill countersink for use in standard drill press chucks and CNC machining centers that accept straight-shank tooling appropriate for a 5/8-inch body diameter.

Installation Notes

This tool is installed and operated by machinists, tool and die technicians, and fabricators using standard drill press or CNC equipment. Secure the shank firmly in the chuck or collet before operation and verify that spindle speed is appropriate for the material and tool diameter. Inspect both cutting ends for wear or chipping before each use. Do not exceed the recommended feed rate for the workpiece material to avoid tool breakage or poor countersink finish quality.
