Value Collection 08906323 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08906323 is a counterbore pilot used to guide counterboring tools during precision machining and fastener seating operations. With a 0.5 inch head diameter and a 0.3125 inch shank diameter, this pilot locates and centers the counterbore cutter to ensure consistent, repeatable results. Constructed from carbon steel with a bright, uncoated finish, it offers reliable performance in general-purpose shop and field applications. Machinists, maintenance technicians, and trade professionals use counterbore pilots to achieve clean, accurately positioned counterbored holes for socket head cap screws and similar fasteners.

This counterbore pilot is suited for use in metalworking, maintenance, and fabrication environments where accurate hole preparation is required. It is appropriate for both bench work and light production setups. The bright finish leaves the tool ready to use out of the package without additional prep. Sold individually, it integrates directly into standard counterboring tool sets that accept a 0.3125 inch shank.

Key Features

• 0.5 inch head diameter for accurate counterbore alignment
• 0.3125 inch shank diameter for standard tool holder compatibility

• Bright, uncoated finish — ready to install without additional treatment
• Sold as a single unit for targeted replacement or inventory stocking

Compatibility

Designed as a general-purpose counterbore pilot for use with standard counterboring tool systems that accept a 0.3125 inch shank diameter pilot.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with manual or CNC machining operations. Secure the pilot firmly in the counterbore tool before use and verify shank fit to prevent runout. Always ensure the workpiece is clamped and the machine spindle is at a complete stop before changing or seating the pilot. Follow applicable shop safety protocols when working with cutting tools and rotating equipment.
