Value Collection 08908287 Counterbore Pilot 7/16 in

Product Description

The VALUE COLLECTION 08908287 is a counterbore pilot used to guide counterboring tools during precision machining and metalworking operations. The pilot features a 7/16 inch head diameter and a 7/16 inch shank diameter, providing a consistent fit in standard counterbore tool holders. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general-purpose shop work where coating-specific requirements are not critical. It is typically installed by machinists, tool-and-die workers, and maintenance technicians performing counterboring on ferrous and non-ferrous workpieces.

Counterbore pilots are used in manufacturing, fabrication, and maintenance environments to maintain concentricity between a counterbore and a pre-drilled pilot hole. This pilot is appropriate for use in manual mills, drill presses, and CNC setups where a 7/16 inch shank is required. It suits residential shop, commercial production, and MRO applications where standard carbon steel tooling meets the job requirements.

Key Features

• 7/16 inch head diameter for accurate counterbore alignment
• 7/16 inch shank diameter fits standard 7/16 inch counterbore tool holders
• Carbon steel construction provides adequate hardness for general-purpose machining
• Bright, uncoated finish allows for easy visual inspection and re-sharpening
• Lightweight at 0.13 pounds for easy handling and tool change

Compatibility

Designed as an OEM-style replacement pilot for standard counterbore tool sets accepting a 7/16 inch shank diameter.

Installation Notes

Installation is performed by machinists or maintenance technicians as part of counterbore tool assembly. Ensure the spindle and workpiece are fully stopped and the machine is powered down before inserting or removing the pilot. Secure the pilot firmly in the counterbore body before operation to prevent slippage and ensure concentricity. Follow applicable shop safety standards and machine manufacturer guidelines during tool setup.
