Value Collection 08902140 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08902140 is a counterbore pilot used to guide counterbore cutters during precision hole preparation in metalworking and machining applications. The pilot features a 7/32 inch head diameter and a 1/8 inch shank diameter, providing proper alignment and centering for the counterbore tool. Constructed from carbon steel with a bright, uncoated finish, this pilot delivers reliable performance in standard shop and field machining tasks. It is a single-piece component suited for use by machinists, maintenance technicians, and trade professionals who perform counterboring on ferrous and non-ferrous materials.

Counterbore pilots are used in applications where a fastener head must sit flush or below the surface of a workpiece. This pilot is appropriate for light-duty and general-purpose machining work in residential, commercial, and industrial maintenance settings. It pairs with counterbore cutter sets to ensure the pilot hole and counterbore are concentric. The 1/8 inch shank diameter seats into the counterbore tool body, while the 7/32 inch head diameter establishes the pilot bore fit.

Key Features

• 7/32 inch head diameter for precise counterbore alignment
• 1/8 inch shank diameter fits standard counterbore tool bodies
• Carbon steel construction provides durability for general machining use
• Bright, uncoated finish allows for easy visual inspection
• Single-piece component for straightforward replacement or stocking

Compatibility

Designed as an OEM-style replacement or stock pilot for counterbore cutter sets requiring a 1/8 inch shank and 7/32 inch head diameter pilot.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard counterbore tooling. Ensure the machine is fully powered down and the spindle is at a complete stop before changing or seating the pilot. The pilot should be seated firmly in the counterbore body before commencing the cut to prevent misalignment or workpiece damage. Follow shop safety protocols and applicable machinery guarding requirements during operation.
