The VALUE COLLECTION 08903205 is a counterbore pilot used to center and guide a counterbore cutter during machining operations. The pilot fits into a drilled hole and aligns the counterbore so the recess seats concentrically with the through-hole. It features a 5/16-inch head diameter and a 5/32-inch shank diameter. The tool is manufactured from carbon steel with a bright, uncoated finish. Machinists and maintenance technicians install this pilot in manual or CNC drilling setups where a flat-bottomed counterbore is required for socket-head cap screws or similar fasteners.
This counterbore pilot is suited for use in machine shops, manufacturing facilities, and field maintenance environments. It is appropriate for ferrous and non-ferrous workpiece materials where a pilot is needed to maintain bore alignment during counterboring. The bright finish leaves the steel uncoated, making it straightforward to inspect for wear. This is a single-piece item sold individually.
Designed as a replacement or spare counterbore pilot for standard counterbore cutter sets requiring a 5/32-inch shank pilot with a 5/16-inch head diameter.
Installation is performed by machining professionals or maintenance technicians familiar with counterboring operations. Before changing or seating the pilot, ensure the machine spindle is fully stopped and locked out per applicable lockout/tagout procedures. The pilot should be inspected for wear or damage before each use, as a worn pilot can cause misalignment and damage the workpiece or cutter.
