Value Collection GH8862161 Solid Pilot Counterbore 13/32 in

Product Description

The VALUE COLLECTION GH8862161 is a solid pilot counterbore designed for accurate, clean countersinking in metalworking and fabrication applications. Built from high-speed steel, this tool produces a flat-bottomed recess around a drilled hole, allowing fastener heads to sit flush or below the workpiece surface. It features a 13/32-inch cutting diameter, a 9/32-inch standard pilot diameter, and a straight cylindrical 3/8-inch shank. The 3-flute design provides a balance of chip clearance and surface finish quality. This tool is suited for use in drill presses, milling machines, and CNC setups where controlled counterbore depth and concentricity are required.

This counterbore is sized for 1/4-inch fastener compatibility, making it a common choice in general machining, sheet metal work, fixture building, and light structural fabrication. The standard pilot keeps the counterbore concentric with an existing pilot hole. Machinists, tool-and-die makers, maintenance technicians, and production shop operators working with steel, aluminum, and similar materials will find this tool fits standard setups without modification. It is sold individually and is appropriate for both production and maintenance-repair-operations environments.

Key Features

• 13/32-inch counterbore diameter sized for 1/4-inch fasteners
• 9/32-inch standard pilot diameter maintains concentricity with pilot hole
• High-speed steel construction provides wear resistance at typical machining speeds
• 3-flute geometry balances chip evacuation and finish quality
• 3/8-inch straight cylindrical shank fits standard drill chucks and collets
• Forward cutting direction for use in conventional right-hand rotation setups

Compatibility

Designed as a standard solid pilot counterbore for use with 1/4-inch fasteners in drill press, milling machine, and CNC applications requiring a 3/8-inch shank tool holder.

Installation Notes

This tool is installed and used by machinists and metalworking professionals. Secure the shank firmly in a drill chuck or collet rated for the 3/8-inch diameter before operation. Ensure the workpiece is clamped securely to prevent movement during cutting. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish.
