Value Collection 08909780 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909780 is a counterbore pilot used to guide counterboring tools during precision drilling operations. The pilot features a 1-3/8 inch head diameter and a 1/2 inch shank diameter, making it suitable for securing consistent bore depth and alignment in metal fabrication and machining applications. Constructed from carbon steel with a bright, uncoated finish, this pilot provides reliable durability for shop and field use. It is sold individually and is appropriate for machinists, millwrights, and maintenance technicians performing counterbore operations on steel and similar materials.

This counterbore pilot is well suited for use in production machining, maintenance repair, and metal fabrication environments. It is designed to seat accurately within a counterbore tool to maintain concentricity during the boring process. Typical applications include preparing bolt-seat recesses in metal assemblies where fastener heads must sit flush or below the work surface. The bright uncoated finish keeps tolerances tight without the dimensional buildup associated with heavy coatings.

Key Features

• 1-3/8 inch head diameter for broad seating coverage
• 1/2 inch shank diameter for standard counterbore tool compatibility
• Carbon steel construction for strength in metalworking applications
• Bright uncoated finish maintains close dimensional tolerances
• Sold as a single unit — no multi-pack quantity required

Compatibility

Designed as a standard counterbore pilot for use with counterboring tools accepting a 1/2 inch shank and a 1-3/8 inch head diameter in general metalworking and machining setups.

Installation Notes

Installation and use of this counterbore pilot should be performed by qualified machinists or maintenance technicians familiar with rotating cutting tools. Ensure the drill press, milling machine, or hand drill is fully powered down and secured before inserting or removing the pilot from the counterbore tool. Verify shank fitment and tool chuck compatibility before operation. Always use appropriate personal protective equipment when operating cutting tools.
