Value Collection BC11P0003 Combo Drill Countersink Cobalt

Product Description

The VALUE COLLECTION BC11P0003 is a combination drill and countersink designed for precise hole preparation in metal, composite, and other hard materials. Built from cobalt steel with a bright, uncoated finish, this tool delivers the heat resistance and edge retention needed for demanding drilling applications. The 1/4-inch body diameter accommodates standard drill chucks, and the 90-degree included angle produces clean, accurate countersunk seats for flathead fasteners. At 2 inches overall length, it is compact enough for confined-space work without sacrificing rigidity. Rated for right-hand cutting, it runs on conventional drill presses, hand drills, and CNC setups alike.

This combo drill countersink is suited for metalworking, fabrication, and maintenance applications where a pilot hole and countersink need to be cut in a single pass. The No. 3 trade size and 7/64-inch point diameter make it a practical choice for smaller fastener sizes commonly used in sheet metal, structural brackets, and general fabrication work. Machinists, maintenance technicians, and experienced tradespeople performing metalwork will find this tool straightforward to integrate into existing setups.

Key Features

• Cobalt steel construction for improved heat and wear resistance compared to standard HSS
• 90-degree included angle for standard flathead fastener countersinking
• 1/4-inch body diameter fits common drill chucks and collets
• 7/64-inch drill point diameter and 7/64-inch drill point length for precise pilot hole entry
• Right-hand cutting direction compatible with conventional drill rotation
• Double end type extends usable tool life

Compatibility

Designed as a standard No. 3 trade size combo drill countersink suitable for use with drill presses, hand drills, and CNC machining centers accepting a 1/4-inch shank.

Installation Notes

Installation is performed by machinists or maintenance technicians using a drill press, hand drill, or CNC machine. Secure the workpiece firmly before drilling to prevent movement and ensure a clean countersink seat. Use appropriate cutting fluid when working with hard metals to extend tool life and maintain point geometry. Inspect the drill point before each use and replace the tool if chipping or excessive wear is observed.
