Value Collection 08908766 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08908766 is a counterbore pilot designed for use with counterbore cutting tools in metal fabrication and mechanical assembly applications. The pilot guides the counterbore cutter along the existing hole centerline, ensuring accurate alignment and a clean, flat-bottomed recess for fastener seating. This pilot features a 1-5/16 inch head diameter and a 7/16 inch shank diameter, and is constructed from carbon steel with a bright, uncoated finish. It is typically installed and used by machinists, tool-and-die technicians, and maintenance mechanics working on precision fastener applications.

This counterbore pilot is suited for use in machine shops, maintenance facilities, and production environments where counterbored holes are required for socket head cap screws, shoulder bolts, or similar recessed fasteners. The carbon steel construction makes it appropriate for use with ferrous and non-ferrous workpiece materials in standard-duty cutting operations. It is sold individually and is intended as a replacement or supplemental pilot for compatible counterbore tool sets.

Key Features

• 1-5/16 inch head diameter for accurate counterbore guidance
• 7/16 inch shank diameter for secure seating in the counterbore body
• Carbon steel construction provides reliable durability in standard-duty applications
• Bright, uncoated finish allows for visual inspection of tool condition
• Sold as a single-piece unit for targeted replacement or tooling setup

Compatibility

Designed as an OEM-style replacement counterbore pilot for use with counterbore cutting tools accepting a 7/16 inch shank diameter pilot.

Installation Notes

Installation of this counterbore pilot is performed by machinists or mechanical technicians using appropriate counterbore tooling and a drill press or milling machine. Ensure the machine is powered down and the spindle is fully stopped before inserting or removing the pilot. The pilot should be seated securely in the counterbore body before beginning any cutting operation to prevent misalignment or tool damage.
