Value Collection 08909483 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909483 is a counterbore pilot tool used to guide counterbore cutters during precision boring operations on metal workpieces. With a 0.75 inch head diameter and a 0.5 inch shank diameter, this pilot fits into standard counterbore holders and keeps the cutter centered over a pilot hole. It is constructed from carbon steel with a bright, uncoated finish. Machinists and tool-and-die technicians use this pilot in manual and CNC machining setups where accurate seat depth and concentricity are required.

This counterbore pilot is suited for general metalworking and machining applications where a 0.5 inch shank and 0.75 inch head diameter are specified. It is commonly used in machine shops, maintenance facilities, and fabrication environments when countersinking or seating fastener heads to a controlled depth. The bright finish leaves the carbon steel surface uncoated, making it appropriate for standard ferrous workpiece applications.

Key Features

• 0.75 inch head diameter for precise counterbore alignment
• 0.5 inch shank diameter fits standard counterbore tool holders
• Carbon steel construction provides adequate hardness for general metalworking
• Bright, uncoated finish — no coating interference with close-tolerance fits
• Lightweight at 0.31 pounds, easy to handle during tool changes

Compatibility

Designed as an OEM-style replacement or direct-fit pilot for counterbore sets accepting a 0.5 inch shank diameter and a 0.75 inch head diameter.

Installation Notes

Installation is performed by machinists or toolroom technicians using standard counterbore holders. Ensure the machine spindle is fully stopped and the tool holder is clean and free of chips before seating the pilot. Secure the pilot firmly in the holder before beginning any cutting operation to prevent runout. Follow your facility safety procedures and applicable machine guarding requirements when operating drilling or boring equipment.
