Value Collection 08903122 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08903122 is a counterbore pilot used to guide counterboring tools during machining operations. It features a 3/16 inch head diameter and a 5/32 inch shank diameter, sized for precision alignment in counterbore setups. Constructed from carbon steel with a bright uncoated finish, this pilot provides reliable rigidity for general-purpose machining work. It is a single-piece item suited for use in machine shops, maintenance facilities, and fabrication environments where consistent counterbore alignment is required.

This counterbore pilot is appropriate for use in bench-top drill press work, CNC machining centers, or manual milling setups where counterbore accuracy is critical. The 5/32 inch shank fits standard counterbore tool bodies designed for that shank size, and the 3/16 inch head diameter corresponds to the pilot hole it is intended to guide. Machinists and maintenance technicians working with fastener counterboring applications will find this pilot compatible with standard tooling setups of matching dimensions.

Key Features

• 3/16 inch head diameter for precise pilot hole alignment
• 5/32 inch shank diameter fits matching counterbore tool bodies
• Carbon steel construction provides rigidity for general-purpose machining
• Bright uncoated finish suitable for standard shop conditions
• Single-piece quantity for individual replacement or tooling builds

Compatibility

Designed as a replacement or spare counterbore pilot for standard counterboring tools accepting a 5/32 inch shank and a 3/16 inch head diameter.

Installation Notes

Counterbore pilots are installed and serviced by machinists or maintenance technicians. Before installing or swapping a pilot, ensure the machine is fully powered down and the spindle is locked. Verify that the shank diameter and head diameter match the counterbore tool body specifications before insertion. Use appropriate hand tools to secure the pilot per the tool body manufacturer guidance.
