Value Collection 08902280 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08902280 is a counterbore pilot used to guide counterbore cutters during precision boring operations. The pilot fits a 1/8 inch shank diameter and is designed to align with a 7/16 inch head diameter counterbore. Machined from carbon steel with a bright, uncoated finish, this pilot delivers consistent alignment and reliable performance in general-purpose machining applications. It is used by machinists, tool and die technicians, and maintenance professionals working with counterbore tool sets on manual mills, drill presses, and CNC setups.

This counterbore pilot is suited for light to medium-duty shop applications where precise bore alignment is required prior to fastener seating. The 1/8 inch shank diameter fits standard counterbore bodies that accept interchangeable pilots, making it a practical replacement or spare component for existing tool sets. It is commonly used in metal fabrication shops, maintenance facilities, and production environments where counterbored holes are required for socket head cap screws and similar fastener types.

Installation Notes

This pilot is installed by machinists and toolroom technicians into compatible counterbore bodies. Ensure the machine spindle is fully stopped and the tool holder is secured before inserting or removing the pilot. The pilot should seat firmly without play in the counterbore body shank bore. Follow shop safety procedures and manufacturer guidelines for the counterbore tool set when selecting feed rates and speeds.
