Value Collection 08903189 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08903189 is a counterbore pilot used to guide counterbore cutting tools during precision boring operations in metalworking and machining applications. The pilot features a 9/32 inch head diameter and a 5/32 inch shank diameter, allowing it to seat correctly within the counterbore tool body and maintain accurate hole alignment. Constructed from carbon steel with a bright uncoated finish, this pilot provides reliable rigidity for shop and production use. It is handled by machinists, tool-and-die makers, and maintenance technicians who require consistent bore alignment when enlarging or finishing drilled holes.

This counterbore pilot is suited for use in machine shops, maintenance facilities, and production environments where counterboring operations require precise pilot guidance. The bright uncoated finish is appropriate for general-purpose carbon steel applications across a range of workpiece materials. It is sold individually and is compatible with standard counterbore tool holders that accept pilots with a 5/32 inch shank diameter and 9/32 inch head diameter.

Key Features

• 9/32 inch head diameter for accurate counterbore seating
• 5/32 inch shank diameter for secure tool body retention
• Carbon steel construction for rigidity in general-purpose machining
• Bright uncoated finish for standard shop applications
• Sold as an individual pilot for targeted replacement or stocking

Compatibility

Designed as a replacement or spare counterbore pilot for standard counterbore tool holders requiring a 5/32 inch shank diameter and a 9/32 inch head diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians. Ensure the counterbore tool is fully removed from the machine spindle and all power is off before inserting or replacing the pilot. The pilot should be seated fully and securely in the counterbore body before operation. Follow applicable shop safety procedures and machine tool manufacturer guidelines during setup.
