Value Collection 08909749 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909749 is a counterbore pilot used to guide counterboring tools during machining operations. It features a 1-1/4 inch head diameter and a 1/2 inch shank diameter, making it suited for standard counterbore setups on drill presses, milling machines, and manual machining equipment. Constructed from carbon steel with a bright, uncoated finish, this pilot provides reliable concentricity during the counterboring process. It is typically installed and used by machinists, tool-and-die professionals, and maintenance technicians performing precision hole-finishing work on ferrous and general-purpose materials.

This counterbore pilot is appropriate for use in light industrial, maintenance, and general machining environments where accurate pilot guidance is required during counterboring. It fits standard counterbore tool bodies that accept a 1/2 inch shank pilot. Typical applications include creating flat-bottomed recesses for socket head cap screws and similar fasteners in metal fabrication and repair work.

Key Features

• 1-1/4 inch head diameter for proper counterbore seating
• 1/2 inch shank diameter for compatibility with standard counterbore bodies
• Carbon steel construction for durability in general machining applications
• Bright, uncoated finish for straightforward dimensional inspection
• Sold individually as a single-piece unit

Compatibility

Designed as a replacement or spare counterbore pilot for standard counterbore tool bodies that accept a 1/2 inch shank diameter pilot. Specific tool body compatibility should be verified against the counterbore manufacturer specifications before installation.

Installation Notes

Installation is typically performed by a machinist or maintenance technician. Ensure the counterbore tool body is fully de-energized and the spindle is locked or powered down before inserting or removing the pilot. The pilot should seat fully and concentrically within the counterbore body before beginning the cut. Inspect the pilot shank for wear or damage before each use to maintain hole accuracy.
