Value Collection 08907362 Counterbore Pilot 9/16 in Head

Product Description

The VALUE COLLECTION 08907362 is a counterbore pilot designed to guide counterbore cutters during precision boring operations on metal workpieces. The pilot fits a 3/8-inch shank diameter and centers the cutter relative to a pre-drilled hole, ensuring accurate seat depth and concentricity. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose shop use. It is a common consumable for machinists, tool and die workers, and maintenance technicians who perform counterboring on steel, iron, and similar ferrous materials.

Counterbore pilots are used in fabrication shops, maintenance facilities, and production environments where fastener seat preparation is required. This pilot is appropriate for use in manual drill press operations and CNC setups where a replaceable or interchangeable pilot is needed to match a specific bolt or fastener clearance diameter. The 3/8-inch shank diameter and 9/16-inch head diameter make it suitable for medium-sized counterbore applications on structural and mechanical assemblies.

Key Features

• 9/16-inch head diameter for accurate cutter centering
• 3/8-inch shank diameter for standard counterbore tool compatibility
• Carbon steel construction provides adequate hardness for general ferrous machining
• Bright, uncoated finish — no coating buildup to affect dimensional tolerances
• Sold as a single unit, allowing replacement without purchasing a full set

Compatibility

Designed as a replacement or spare pilot for counterbore tool sets accepting a 3/8-inch shank diameter and 9/16-inch head diameter pilot.

Installation Notes

Counterbore pilots are installed by machinists or maintenance technicians as part of a counterbore cutter assembly. Secure the workpiece firmly before operation and ensure the pilot diameter matches the existing pilot hole for proper alignment. Inspect the pilot for wear or damage before each use, as a worn pilot will compromise cutter concentricity. Follow applicable shop safety practices and machine guard requirements when operating drill presses or milling equipment.
