Keo 906-000-019 Combo Drill Countersink 1/8 in Hss

Product Description

The KEO 906-000-019 is a combination drill and countersink tool designed to perform pilot drilling and countersinking in a single operation. Built from high-speed steel with a bright, uncoated finish, it suits general-purpose machining and fabrication work. The tool measures 1.25 inches in overall length with a 1/8-inch body diameter and a 0.0200-inch drill point diameter. It features a 118-degree drill point angle and a 60-degree included angle for the countersink profile. Right-hand cutting direction and a plain cutting edge style make it compatible with standard drill press and CNC setups used by machinists and metalworkers.

This combo drill countersink is intended for countersinking applications where a clean, accurately angled seat is required before fastener installation. The aircraft style designation and double end type make it a practical choice for light-gauge metal fabrication, sheet metal work, and precision assembly tasks. At trade size 3/0 with a 0.0200-inch drill point, it is suited to small-diameter fastener prep work in both production and maintenance environments.

Key Features

• Combines pilot drilling and countersinking in one pass, reducing tool changes
• High-speed steel construction for durability across common metal materials
• 118-degree drill point angle for efficient penetration in standard metals
• 60-degree included angle produces consistent countersink seats
• Double end type extends usable tool life
• Aircraft style design for precision small-diameter fastener applications

Compatibility

Designed as an OEM-style combo drill countersink for use in standard drill press, hand drill, and CNC spindle chucks accepting 1/8-inch shank tooling.

Installation Notes

Installation and use should be performed by qualified machinists or fabricators familiar with rotating cutting tools. Secure the workpiece fully before operation and confirm chuck engagement before running the spindle. Use appropriate cutting fluid for the material being worked to extend tool life and improve finish quality. Inspect the cutting edges before each use and replace the tool if chipping or wear is observed.
