Value Collection 08903163 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08903163 is a counterbore pilot used to guide counterboring operations during precision machining and metalworking. It features a 1/4 inch head diameter and a 5/32 inch shank diameter, allowing it to seat correctly in a counterbore tool body and maintain alignment during cutting. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose shop use. It is installed and used by machinists, tool and die technicians, and maintenance professionals working with counterbore sets on ferrous and non-ferrous materials.

This counterbore pilot fits standard counterbore tool bodies that accept a 5/32 inch shank. It is used in machine shops, maintenance facilities, and fabrication environments where accurate counterboring is required for socket head cap screws, shoulder bolts, and similar fastener seats. The 1/4 inch head diameter corresponds to common screw body clearance requirements in light to medium duty assemblies.

Key Features

• 1/4 inch head diameter for accurate counterbore alignment
• 5/32 inch shank diameter for compatibility with standard counterbore tool bodies
• Carbon steel construction for general-purpose machining applications
• Bright, uncoated finish for easy inspection and measurement verification
• Sold individually, suitable for replacement or kit supplementation

Compatibility

Designed as a replacement or spare counterbore pilot for standard counterbore tool bodies accepting a 5/32 inch shank diameter with a 1/4 inch head diameter.

Installation Notes

Counterbore pilots are installed by machinists into counterbore tool bodies before use. Ensure the tool body and spindle are fully de-energized and secured before changing pilots. Verify pilot shank fit is snug with no lateral play before beginning any cutting operation. Follow applicable shop safety standards and manufacturer guidelines for the counterbore tool body in use.
