Value Collection 08907529 Counterbore Pilot 13/16 in Head

Product Description

The VALUE COLLECTION 08907529 is a counterbore pilot used to guide counterbore cutters during precision boring operations. The pilot features a 13/16 inch head diameter and a 3/8 inch shank diameter, making it suited for standard counterbore setups in metal fabrication and mechanical assembly work. Constructed from carbon steel with a bright, uncoated finish, this pilot provides reliable concentricity and alignment when seating fastener heads flush or below a workpiece surface. It is typically installed and used by machinists, tool and die technicians, and maintenance professionals working with drill presses, milling machines, or hand-held power tools.

This counterbore pilot is appropriate for use in general manufacturing, maintenance and repair operations, and assembly environments where consistent fastener seating is required. The 3/8 inch shank fits standard counterbore cutter bodies designed to accept that shank size. The bright, uncoated carbon steel construction suits dry or lightly lubricated cutting conditions in ferrous and non-ferrous workpieces. No specialized mounting hardware is required beyond the compatible counterbore body.

Key Features

• 13/16 inch head diameter for precise counterbore guidance
• 3/8 inch shank diameter for standard counterbore cutter body fitment
• Carbon steel construction for durability in general machining applications
• Bright, uncoated finish — no coating to affect dimensional tolerances
• Sold individually for single-unit replacement or supplemental tooling needs

Compatibility

Designed as a replacement or supplemental pilot for counterbore cutter bodies accepting a 3/8 inch shank and a 13/16 inch head diameter pilot.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with counterbore tooling. Ensure the machine spindle is fully stopped and powered down before inserting or removing the pilot from the counterbore body. Secure the pilot firmly within the counterbore cutter body according to the cutter manufacturer's procedure before beginning any cutting operation. Inspect the pilot shank and head for wear or damage before each use to maintain bore accuracy.
