Value Collection 08909608 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909608 is a counterbore pilot used to guide counterboring tools during precision drilling and boring operations. It features a 15/16 inch head diameter and a 1/2 inch shank diameter, sized for common counterboring applications on metal workpieces. Constructed from carbon steel with a bright, uncoated finish, this pilot provides the rigidity needed to maintain accurate hole alignment when seating fastener heads flush or below a surface. Machinists, maintenance technicians, and fabricators use counterbore pilots as alignment aids in drill press and milling setups.

This counterbore pilot is suited for metalworking operations where fastener counterbores must be concentric with a pre-drilled hole. Typical applications include preparing bolt and cap screw seats in steel and similar materials. The 1/2 inch shank seats into the counterbore tool body, while the 15/16 inch head diameter corresponds to the counterbore size being cut. This pilot is sold as a single unit and is appropriate for job shop, maintenance, and production environments.

Key Features

• 15/16 inch head diameter sized to guide the counterboring cutter
• 1/2 inch shank diameter for secure seating in the counterbore tool body
• Carbon steel construction provides adequate rigidity for metal boring applications
• Bright, uncoated finish for straightforward dimensional inspection
• Sold individually, one pilot per package

Compatibility

Designed as a replacement or supplemental pilot for counterboring tools accepting a 1/2 inch shank and a 15/16 inch head diameter. Verify tool body specifications before ordering.

Installation Notes

Installation of counterbore pilots should be performed by a qualified machinist or tooling technician. Ensure the drill press or milling machine is fully powered down and the spindle is locked before inserting or removing the pilot from the tool body. Confirm that the pilot shank is fully seated and secured in the counterbore tool before beginning any cutting operation. Inspect the pilot for wear or damage before each use to maintain bore concentricity.
