Keo 907-000-160 Combo Drill Countersink Size 6

Product Description

The KEO 907-000-160 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 features a 0.5-inch body diameter, a 7/32-inch drill point diameter, and an 82-degree included angle suited for standard flat-head fastener seating. The 4-inch overall length classifies this as a long-length tool, providing reach in deeper or obstructed work areas. Right-hand cutting direction and a plain cutting edge style make it straightforward to run in conventional drill presses and hand-held power tools. Machinists, fabricators, and maintenance technicians working with metal stock install this tool in production and field repair applications.

The 907-000-160 is applied wherever a pilot hole and countersink must be produced in one pass, reducing setup time and improving hole concentricity. It is suited for use in steel, aluminum, and other machinable metals in both shop and field environments. The size 6 trade designation aligns with standard flat-head machine screw sizing. Its double-end type design extends tool life by providing two usable cutting ends before replacement is needed.

Key Features

• High-speed steel construction for durability across a range of machinable metals
• 0.5-inch body diameter with 7/32-inch drill point for size 6 fastener preparation
• 82-degree included angle for standard flat-head and oval-head fastener countersinks
• 118-degree drill point angle for efficient center-starting and chip clearance
• Double-end design extends usable tool life
• Long-length at 4 inches overall for access in deeper or restricted work positions

Compatibility

Designed as a standard combination drill and countersink for use with size 6 flat-head fasteners in conventional drill press chucks and compatible hand-held power tool setups that accept 0.5-inch shank tooling.

Installation Notes

This tool is installed by machinists and maintenance technicians using a drill press or hand-held power drill with an appropriate chuck. Secure the workpiece fully before operation to prevent movement during cutting. Use cutting fluid when working with steel to manage heat and extend tool life. Inspect both cutting ends for wear or chipping before use.
