Value Collection 08909806 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909806 is a counterbore pilot used to guide counterbore cutters during machining operations. The pilot centers the cutter over a pre-drilled hole, ensuring accurate seat depth and concentricity when recessing fastener heads. It features a 1-7/16 inch head diameter and a 1/2 inch shank diameter, machined from carbon steel with a bright, uncoated finish. This tool is suited for metalworking and fabrication environments where consistent counterbore alignment is required. Machinists and tool and die technicians are the primary users of this type of pilot in shop and production settings.

The 08909806 counterbore pilot is used in drill press, milling machine, and manual machining setups wherever a recessed seat is needed for socket head cap screws, hex bolts, or similar fasteners. Its carbon steel construction provides the rigidity needed for standard ferrous and non-ferrous workpiece materials. The bright, uncoated finish allows for close dimensional inspection prior to use. This pilot is appropriate for general industrial fabrication, maintenance shops, and production machining applications.

Key Features

• 1-7/16 inch head diameter for accurate counterbore seating
• 1/2 inch shank diameter for standard holder compatibility
• Carbon steel construction for rigidity in general machining applications
• Bright, uncoated finish allows easy dimensional verification
• Compact form factor suited for drill press and milling setups

Compatibility

Designed as an OEM-style replacement or standard counterbore pilot for use with compatible 1/2 inch shank counterbore cutter sets in general machining applications.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Ensure the machine spindle is fully powered down and locked out before inserting or removing the pilot from the holder. Verify shank fit and pilot-to-hole clearance before beginning the counterbore operation. Do not force the pilot into an undersized holder.
