Value Collection 08909863 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909863 is a counterbore pilot used to guide counterbore cutters during precision boring operations on metal workpieces. It features a 1.625-inch head diameter and a 0.5-inch shank diameter, making it a standard size for common counterbore tooling setups. Constructed from carbon steel with a bright, uncoated finish, this pilot provides reliable concentricity and support during the counterboring process. It is typically installed and used by machinists, tool-and-die workers, and maintenance technicians performing metal fabrication or mechanical assembly work.

This counterbore pilot is suited for use in machine shops, manufacturing facilities, and maintenance environments where accurate counterbore alignment is required. It fits into compatible counterbore cutter bodies that accept a 0.5-inch shank pilot, supporting clean, square-shouldered counterbore cuts in carbon steel, aluminum, and similar machinable materials.

Key Features

• 1.625-inch head diameter for standard counterbore alignment
• 0.5-inch shank diameter for compatibility with matching counterbore cutter bodies
• Carbon steel construction for durability in general-purpose machining
• Bright, uncoated finish suitable for use with cutting fluids
• Sold individually — one pilot per package

Compatibility

Designed as a replacement or spare pilot for counterbore cutter sets accepting a 0.5-inch shank diameter and a 1.625-inch head diameter. Verify pilot dimensions against your counterbore cutter body specifications before installation.

Installation Notes

Installation is typically performed by a machinist or mechanical technician. Ensure the machine spindle is fully powered down and locked out before inserting or removing the pilot from the counterbore body. Confirm that the pilot seats securely and without play in the cutter body before beginning any cutting operation. Use appropriate cutting fluid for the workpiece material to extend pilot and cutter life.
