Keo 906-000-132 Combo Drill Countersink Size 5 Hss

Product Description

The KEO 906-000-132 is a combination drill and countersink designed for simultaneous drilling and countersinking in a single pass. Built from high-speed steel with a titanium nitride coating, it delivers extended tool life in ferrous and non-ferrous materials. The 3/16 inch drill point produces a center hole while the 82-degree included angle creates a clean countersunk seat. At 2-3/4 inches overall length with a 7/16 inch body diameter, it is sized for benchtop drill presses and CNC machining centers. This tool is standard in metal fabrication shops, machine shops, and maintenance environments where consistent countersinking is required.

This combo drill countersink is suited for metalworking applications where a center drill and countersink operation must be combined into one step. The right-hand cutting direction makes it compatible with standard drill presses, lathes, and vertical machining centers. It is commonly used to prepare workpieces for flat-head fasteners requiring an 82-degree countersunk seat. The plain cutting edge style and double end type allow for straightforward use without special holders or adapters.

Key Features

• High-speed steel construction for durability in general-purpose machining

Compatibility

Designed as a standard size 5 combo drill countersink for use in drill presses, lathes, and CNC machining centers accepting a 7/16 inch body diameter tool.

Installation Notes

This tool is installed and operated by machinists or metalworking technicians using standard drill press or lathe chuck equipment. Ensure the spindle is fully stopped and the machine is powered off before securing or removing the tool from the chuck. Use appropriate cutting fluid for the workpiece material to maximize tool life and surface finish quality. Always inspect the cutting edges for wear or chipping before each use.
