Value Collection 08904302 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08904302 is a counterbore pilot used to guide counterbore cutting tools during precision machining operations. The pilot centers the counterbore cutter over an existing hole, ensuring accurate alignment and a clean, flat-bottomed recess for fastener seating. Machined from carbon steel with a bright, uncoated finish, this pilot measures 15/32 inches in head diameter and 3/16 inches in shank diameter. It is a standard single-piece tool component used by machinists, maintenance technicians, and metalworking trades on drill press, mill, or hand-held drilling setups.

This counterbore pilot is suited for metalworking applications where a fastener head or bearing surface must sit flush or below the workpiece surface. Typical use cases include fabrication shops, machine shops, and maintenance environments working with carbon steel, aluminum, or similar materials. The 3/16 inch shank diameter fits standard counterbore bodies designed for that pilot size, and the 15/32 inch head diameter governs the pilot bore alignment for the corresponding counterbore cutter.

Key Features

• 15/32 inch head diameter for precise bore alignment
• 3/16 inch shank diameter fits standard compatible counterbore tool bodies
• Carbon steel construction provides adequate hardness for general metalworking applications
• Bright, uncoated finish allows easy visual inspection for wear or damage
• Single-piece unit sold individually for targeted replacement or tooling builds

Compatibility

Designed as a replacement or supplemental pilot for counterbore tool sets accepting a 3/16 inch shank pilot with a 15/32 inch head diameter.

Installation Notes

Installation is performed by machinists or tool-and-die technicians familiar with counterboring operations. Ensure the machine is fully powered down and the spindle is locked before inserting or removing the pilot from the counterbore body. Verify that the shank fit is secure and free of debris before beginning any cutting operation. Inspect the pilot for wear, burrs, or deformation prior to each use to maintain accurate alignment.
