Value Collection 08907560 Counterbore Pilot 7/8 in Head

Product Description

The VALUE COLLECTION 08907560 is a counterbore pilot used to guide counterboring tools during precision drilling and spotfacing operations. The pilot fits into the existing bore hole and keeps the counterbore cutter centered, producing clean, accurate seat surfaces for fastener heads and bearing fits. Machined from carbon steel with a bright uncoated finish, this pilot is sized for a 7/8 inch head diameter and a 3/8 inch shank diameter. It is a standard tooling component used in machine shops, fabrication facilities, and maintenance environments where accurate counterboring is required.

This counterbore pilot is suited for use in metalworking and general industrial machining applications where a 3/8 inch shank is required. It is compatible with counterbore tool sets and holders designed to accept a 3/8 inch pilot shank. Typical use cases include creating flat-bottom recesses for socket head cap screws, dowel pin seats, and similar fastener clearance applications in carbon steel, aluminum, and other machinable materials.

Key Features

• 7/8 inch head diameter for accurate counterbore seating
• 3/8 inch shank diameter for standard counterbore holder compatibility
• Carbon steel construction provides adequate hardness for general metalworking
• Bright uncoated finish for easy inspection and dimensional verification
• Sold individually as a single replacement pilot

Compatibility

Designed as a replacement or spare counterbore pilot for counterboring tool sets and holders accepting a 3/8 inch shank diameter pilot.

Installation Notes

Counterbore pilots are installed and serviced by machinists and maintenance technicians. Ensure the mating counterbore tool and holder are free of chips and debris before inserting the pilot. Verify shank fit and pilot retention per the tool manufacturer's procedure before running the spindle. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore quality.
