Value Collection 08909525 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909525 is a counterbore pilot used to guide counterbore cutters during machining operations. It features a 13/16 inch head diameter and a 1/2 inch shank diameter, providing a stable, centered interface between the cutter and the workpiece. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose counterboring in metal fabrication, maintenance, and repair applications. Machinists and tooling technicians install this pilot to ensure accurate seating of fastener heads and prevent cutter walk during the counterboring process.

This counterbore pilot is appropriate for use in machine shops, manufacturing facilities, and maintenance environments where precise counterbore alignment is required. It fits counterbore tool sets that accept a 1/2 inch shank pilot and produce a 13/16 inch head diameter seat. Typical applications include creating flush or recessed seats for socket head cap screws and similar fasteners in steel, aluminum, and other machinable materials.

Key Features

• 13/16 inch head diameter for accurate counterbore seat sizing
• 1/2 inch shank diameter for secure tool holder engagement
• Carbon steel construction for durability in general machining applications
• Bright, uncoated finish suitable for standard shop conditions
• Sold as a single-piece unit for individual replacement or tooling builds

Compatibility

Designed as a replacement or supplemental pilot for counterbore tool sets requiring a 1/2 inch shank diameter and a 13/16 inch head diameter seat.

Installation Notes

Installation is performed by machinists or tooling technicians using standard drill press or milling machine setups. Ensure the machine is powered down and the spindle is fully stopped before changing or seating the pilot. Verify shank fit and head diameter match the counterbore body specifications before use. Follow applicable shop safety procedures and equipment manufacturer guidelines during tool changes.
