Value Collection CD60016 Solid Pilot Counterbore 13/32 in

Product Description

The VALUE COLLECTION CD60016 is a solid pilot counterbore designed for precision spotfacing and counterboring operations in metalworking applications. Built from cobalt steel with a bright, uncoated finish, this tool delivers durability in both hand-feed and machine operations. The 13/32 inch cutting diameter pairs with a 9/32 inch pilot diameter to guide the tool accurately into pre-drilled holes. A straight-cylindrical 3/8 inch shank provides a secure grip in standard drill chucks and milling machine collets. With 3 flutes and a forward cutting direction, the CD60016 produces clean, flat-bottomed seats suitable for socket-head cap screw installations. Licensed machinists and tool-and-die professionals routinely specify this type of counterbore for close-tolerance work.

This counterbore is sized specifically for 1/4 inch socket-head cap screw compatibility, making it a direct-fit choice when preparing seating surfaces for SHCS fasteners in steel, cast iron, aluminum, and similar materials. At 4-1/2 inches overall length, it accommodates typical milling machine setups and drill press applications. The cobalt steel construction provides improved heat and wear resistance compared to standard high-speed steel, making it suitable for tougher alloys and higher spindle speeds. Machinists working in production shops, maintenance environments, or tool rooms will find this counterbore appropriate for both manual and CNC-guided spotfacing tasks.

Key Features

• 13/32 inch counterbore diameter sized for 1/4 inch socket-head cap screw seating
• 9/32 inch pilot diameter for accurate alignment in pre-drilled holes
• Cobalt steel construction for enhanced heat resistance and extended tool life
• 3-flute geometry with forward cutting direction for clean flat-bottomed seats
• Straight-cylindrical 3/8 inch shank for compatibility with standard chucks and collets
• Bright, uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed for use with 1/4 inch socket-head cap screws. The 9/32 inch pilot is intended to locate in the clearance hole produced for a 1/4 inch fastener. Suitable for use in drill presses, knee mills, and CNC machining centers equipped with a 3/8 inch collet or drill chuck.

Installation Notes

This tool is installed and used by machinists and toolmakers in machine shop environments. Secure the shank firmly in a 3/8 inch collet or drill chuck before operation and verify pilot alignment with the existing clearance hole before engaging the cut. Always apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Inspect the pilot and cutting edges for wear before each use and replace the tool if chipping or dulling is observed.
