Keo 906-000-162 Combo Drill Countersink Size 7 Hss

Product Description

The KEO 906-000-162 is a combination drill and countersink tool designed for simultaneous drilling and countersinking in a single operation. Built from high-speed steel with a titanium nitride coating, it delivers improved wear resistance and longer tool life in production and job-site environments. The tool features a 5/8 inch body diameter, a 1/4 inch drill point diameter, and a 118-degree drill point angle. With an 82-degree included angle and plain cutting edge style, it produces clean, accurate countersink seats for flat-head fasteners. It is installed and used by machinists, metalworkers, and trade professionals working with ferrous and non-ferrous materials.

This combo drill countersink is suited for countersinking applications in metal fabrication, HVAC ductwork assembly, electrical enclosure work, and general mechanical assembly. The right-hand cut configuration and double end type make it compatible with standard drill press and hand-drill setups. It is a non-tapered, non-aircraft-style tool appropriate for standard trade countersinking tasks where a size 7 trade size is specified.

Installation Notes

This tool is installed by machinists and trade professionals using standard drill presses, CNC equipment, or hand drills with appropriate chuck capacity. Ensure the workpiece is secured before operation and that spindle speed is set appropriately for the material being drilled. Inspect the cutting edges before use and replace or rotate to the unused end when wear is detected. Follow applicable shop safety and tool-handling procedures during installation and use.
