Value Collection 08909723 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909723 is a counterbore pilot used to guide counterboring tools during precision drilling and boring operations. With a 1-3/16 inch head diameter and a 1/2 inch shank diameter, this pilot fits into the pilot hole to center the counterbore cutter and keep it aligned during the cut. It is machined from carbon steel with a bright, uncoated finish, making it a solid general-purpose option for metalworking, fabrication, and maintenance applications. Machinists and maintenance technicians use counterbore pilots when producing flat-bottomed recesses for socket head cap screws or similar fastener heads that must sit flush or below a workpiece surface.

This counterbore pilot is suited for use in machine shops, fabrication facilities, and maintenance environments where consistent, accurate counterboring is required. It is typically used with a matching counterbore body to produce clean recesses in ferrous and non-ferrous materials. The 1/2 inch shank diameter determines which counterbore body this pilot is compatible with, so confirm the body specification before installation.

Key Features

• 1-3/16 inch head diameter for proper counterbore alignment and support
• 1/2 inch shank diameter for compatibility with standard counterbore bodies
• Carbon steel construction provides adequate hardness for general metalworking use
• Bright, uncoated finish — no additional coating to affect dimensional tolerances
• Sold as a single unit, ideal for replacement or matched-set builds

Compatibility

Designed as a replacement or spare counterbore pilot for use with counterbore bodies accepting a 1/2 inch shank diameter pilot. Verify counterbore body pilot bore size before ordering to confirm fit.

Installation Notes

Counterbore pilots are installed by machinists or toolroom technicians as part of a counterbore tool assembly. Ensure the machine spindle is fully stopped and the tool is secured in the holder before inserting or removing the pilot. The pilot slip-fits into the counterbore body and should be inspected for wear or damage before each use. Follow shop safety procedures and applicable machining standards when operating cutting tools.
