Value Collection 08905283 Counterbore Pilot 7/16 in Head

Product Description

The VALUE COLLECTION 08905283 is a counterbore pilot used to guide counterbore cutters during machining and fabrication operations. The pilot seats into the counterbore tool shank and centers the cutter over a pre-drilled hole, producing clean, concentric counterbored seats for socket head cap screws and similar fasteners. Constructed from carbon steel with a bright, uncoated finish, this pilot features a 7/16 inch head diameter and a 1/4 inch shank diameter. Machinists, tool-and-die workers, and maintenance technicians install this type of pilot when setting up manual or CNC machine tools for counterboring work.

This counterbore pilot is suited for use in general metalworking, maintenance, and fabrication shops where standard counterbore setups are required. The 1/4 inch shank diameter fits counterbore holders designed for that shank size, making it a common replacement or spare pilot for bench-top drill presses and milling setups. It is appropriate for light-duty to medium-duty counterboring applications in ferrous and non-ferrous materials.

Key Features

• 7/16 inch head diameter for precise counterbore centering
• 1/4 inch shank diameter for compatibility with standard counterbore holders
• Carbon steel construction for durability in general machining applications
• Bright, uncoated finish for easy inspection and corrosion monitoring
• Compact and lightweight at 0.12 pounds for easy tool-change handling

Compatibility

Designed as a standard replacement or spare pilot for counterbore sets and holders accepting a 1/4 inch shank diameter pilot with a 7/16 inch head diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians as part of counterbore tool setup. Ensure the machine spindle is fully de-energized and the tool holder is secured before inserting or removing the pilot. The pilot should seat firmly in the counterbore body with no lateral play before beginning the cut. Follow applicable shop safety procedures and machine manufacturer guidelines during tool changes.
