Value Collection 08908444 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08908444 is a counterbore pilot used to guide counterboring tools during precision drilling and boring operations. The pilot features an 11/16-inch head diameter and a 7/16-inch shank diameter, making it suitable for controlled material removal in metal fabrication and mechanical assembly work. Constructed from carbon steel with a bright uncoated finish, this pilot is designed for use in machine shop, maintenance, and general metalworking environments. It is installed by machinists and maintenance technicians who require accurate pilot guidance when creating counterbored holes for socket head cap screws and similar fasteners.

This counterbore pilot is suited for use in light to medium-duty machining applications involving ferrous and non-ferrous metals. It is used in conjunction with counterboring tools to ensure concentricity and alignment during hole finishing operations. Typical install scenarios include manufacturing assembly lines, maintenance repair operations, and job shop environments where consistent hole quality is required. The part ships in a single-unit package quantity.

Key Features

• 11/16-inch head diameter for precise counterbore guidance
• 7/16-inch shank diameter for secure tool engagement
• Carbon steel construction for durability in metalworking applications
• Bright uncoated finish for dimensional accuracy without coating buildup
• Single-unit packaging for individual replacement or tooling builds

Compatibility

Designed as a replacement or supplemental pilot for standard counterboring tools accepting a 7/16-inch shank and 11/16-inch head diameter pilot configuration.

Installation Notes

Installation is performed by machinists or maintenance technicians using standard machine tool equipment. Ensure the counterboring tool and spindle are fully powered down and locked out before inserting or removing the pilot. Verify that the pilot shank is fully seated and secure in the counterbore tool body before beginning any cutting operation. Follow applicable shop safety procedures and manufacturer guidelines for cutting speeds and feed rates based on workpiece material.
