Value Collection 08904328 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08904328 is a counterbore pilot used to guide counterbore cutting tools during precision machining operations. The pilot seats in the bore of a counterbore cutter and aligns the tool concentrically with a pre-drilled hole, ensuring accurate spotfacing and seat cutting. This pilot features a 0.5 inch head diameter and a 3/16 inch shank diameter. It is constructed from carbon steel with a bright, uncoated finish. Machinists, tool and die makers, and maintenance technicians working with manual or CNC machine tools rely on pilots like this one to maintain alignment and surface quality in counterbore applications.

This counterbore pilot is suited for use in shop environments where consistent bore alignment is required. It is appropriate for general-purpose metalworking, maintenance and repair operations, and production machining on ferrous and compatible non-ferrous materials. The carbon steel construction makes it a practical choice for standard-duty applications where high-speed steel or carbide tooling is not required. It is sold as a single unit.

Key Features

• 0.5 inch head diameter for secure seating in compatible counterbore cutters
• 3/16 inch shank diameter for alignment with corresponding pre-drilled pilot holes
• Carbon steel construction for general-purpose, standard-duty machining use
• Bright, uncoated finish — no additional coating to affect dimensional tolerances
• Sold as a single pilot for targeted replacement or tooling builds

Compatibility

Designed as a standard counterbore pilot for use with counterbore cutters accepting a 0.5 inch head diameter and 3/16 inch shank. Verify pilot head and shank dimensions against your specific counterbore cutter specifications before installation.

Installation Notes

Counterbore pilots are installed and serviced by machinists or maintenance technicians familiar with rotating cutting tools. Before changing or seating a pilot, ensure the machine spindle is fully stopped and locked out in accordance with applicable lockout/tagout procedures. Confirm that pilot dimensions match the counterbore cutter bore and the workpiece pilot hole diameter before beginning the cut. Inspect the pilot for wear or runout before each use to avoid misalignment and surface defects.
