Value Collection 08904161 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08904161 is a counterbore pilot used to guide counterbore cutters during precision machining and fastener seating operations. It features a 1/4 inch head diameter and a 3/16 inch shank diameter, machined from carbon steel with a bright, uncoated finish. The pilot centers the counterbore tool over a pilot hole to ensure accurate, concentric cuts that allow fastener heads to sit flush or below the workpiece surface. It is installed and used by machinists, tool and die technicians, and maintenance professionals working in metal fabrication and repair environments.

This counterbore pilot is suited for use in general metalworking, fabrication shops, and maintenance facilities where consistent fastener seating is required. The 3/16 inch shank fits standard counterbore tool holders of the corresponding bore size. The carbon steel construction handles typical shop drilling and machining loads in ferrous and non-ferrous workpieces.

Key Features

Installation Notes

Counterbore pilots are installed and removed by qualified machinists or maintenance technicians. Ensure the machine spindle is fully powered down and at rest before inserting or removing the pilot from the counterbore body. Confirm the pilot shank diameter matches the counterbore receiver bore before use to prevent tool damage or workpiece misalignment. Follow applicable shop safety protocols and relevant facility equipment standards during all tooling changes.
