Value Collection 08904229 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08904229 is a counterbore pilot used to guide counterboring tools during precision hole finishing operations. The pilot features an 11/32-inch head diameter and a 3/16-inch shank diameter, sized for controlled engagement with the counterbore tool body. Constructed from carbon steel with a bright uncoated finish, this pilot is suited for general machining and metalworking environments where accurate seat depth and alignment are required. It is typically installed and used by machinists and toolroom technicians performing counterboring operations on ferrous and non-ferrous materials.

This counterbore pilot is appropriate for use in production machining, maintenance, and repair operations where a standard 3/16-inch shank counterbore pilot is needed. It fits standard counterbore tool bodies that accept a 3/16-inch pilot shank and produces a finished seat accommodating an 11/32-inch head diameter fastener. Suitable for light industrial and job-shop applications requiring consistent fastener seating and bore alignment.

Key Features

• 11/32-inch head diameter for accurate fastener seat finishing
• 3/16-inch shank diameter for standard counterbore tool body compatibility
• Carbon steel construction provides durability in general machining applications
• Bright uncoated finish — no coating buildup to affect dimensional accuracy
• Compact and lightweight at 0.2 pounds for easy handling and storage

Compatibility

Designed as a standard replacement or spare counterbore pilot for counterbore tool sets accepting a 3/16-inch pilot shank diameter.

Installation Notes

Installation of counterbore pilots is performed by machinists using appropriate arbor presses or hand tools to seat the pilot securely in the counterbore tool body. Ensure the machine spindle is fully de-energized and the workpiece is firmly clamped before beginning any counterboring operation. Inspect the pilot shank and tool body bore for debris or wear before assembly. Do not force-fit a pilot that shows signs of damage or dimensional variance.
