Value Collection 08902165 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08902165 is a counterbore pilot used to guide counterbore cutters during machining operations. It features a 0.25 inch head diameter and a 0.125 inch shank diameter, making it suited for precision hole preparation in metal fabrication and mechanical assembly work. Constructed from carbon steel with a bright uncoated finish, this pilot provides adequate rigidity for standard counterboring tasks. Machinists, tool and die workers, and general fabrication professionals install this type of pilot to maintain concentricity between a drilled hole and the counterbore seat.

This counterbore pilot is appropriate for use in manual mills, drill presses, and CNC machining centers where a counterbore cutter requires a center-guiding pilot. It is suited for light to medium-duty applications in carbon steel, aluminum, and similar machinable materials. The bright uncoated finish means it is best used in dry or lightly lubricated cutting conditions where coating-related concerns such as chip adhesion or heat buildup are not primary factors.

Key Features

• 0.25 inch head diameter for standard counterbore cutter fitment
• 0.125 inch shank diameter for secure seating in compatible pilot bore
• Carbon steel construction provides rigidity for typical machining loads
• Bright uncoated finish suitable for general-purpose dry or lightly lubricated use
• Compact and lightweight at 0.6 pounds for easy handling and storage

Compatibility

Designed as a standard counterbore pilot for use with compatible counterbore cutter sets requiring a 0.125 inch shank and 0.25 inch head pilot.

Installation Notes

Installation is typically performed by a machinist or tool room technician. Before mounting the pilot, ensure the machine spindle is fully powered down and the cutter body is secure. The pilot should seat snugly in the counterbore cutter without play; a loose pilot will cause runout and poor seat finish. Follow applicable shop safety procedures and manufacturer cutter guidelines when selecting feed rates and cutting fluids.
