Value Collection 08902322 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08902322 is a counterbore pilot used to guide counterbore cutters during precision boring operations. It features a 0.5 inch head diameter and a 0.125 inch shank diameter, machined from carbon steel with a bright, uncoated finish. This pilot locates the cutter concentrically over a pre-drilled hole, ensuring accurate seat depth and alignment when countersinking fastener recesses. Machinists, maintenance technicians, and metalworking tradespeople use this type of pilot in manual and CNC drilling setups. The carbon steel construction provides adequate rigidity for general-purpose boring in ferrous and non-ferrous materials.

This counterbore pilot is suited for bench work, drill press, and mill applications in light manufacturing, maintenance, and repair environments. It is used wherever a fastener recess must be bored to accept a socket head cap screw or similar fastener head, ensuring a flush or sub-flush seating surface. The bright, uncoated finish is appropriate for general shop use where corrosion exposure is minimal.

Key Features

• 0.5 inch head diameter for accurate counterbore guidance
• 0.125 inch shank diameter for secure chuck or holder engagement
• Carbon steel construction for general-purpose rigidity
• Bright, uncoated finish for consistent dimensional tolerances
• Compact and lightweight at 0.05 pounds

Compatibility

Designed as a standard counterbore pilot for use with compatible counterbore cutter sets requiring a 0.125 inch shank and 0.5 inch head diameter pilot.

Installation Notes

Secure the pilot firmly in the counterbore cutter body before beginning any boring operation. Ensure the workpiece is clamped and the drill press or mill is powered down before changing or seating the pilot. Verify pilot shank fit and cutter body compatibility before use to prevent runout or chatter during the cut.
