Value Collection 08905226 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08905226 is a counterbore pilot used to guide counterbore cutters during precision boring operations on metal, wood, and composite workpieces. The pilot features an 11/32 inch head diameter and a 1/4 inch shank diameter, allowing it to seat accurately in a pre-drilled hole while the counterbore cutter removes material around it. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general shop and field machining tasks where consistent bore alignment is required. Machinists, tool-and-die techs, and maintenance mechanics typically use counterbore pilots when fastener head recessing is part of the assembly workflow.

Counterbore pilots are used in residential and commercial maintenance, fabrication shops, and industrial assembly environments. This pilot is appropriate for applications where socket head cap screws or other recessed fasteners must sit flush or below a workpiece surface. The 1/4 inch shank diameter fits standard counterbore tool holders designed for that shank size, and the 11/32 inch head diameter corresponds to the pilot hole size the cutter will be guided through.

Key Features

• 11/32 inch head diameter for accurate pilot hole engagement
• 1/4 inch shank diameter fits standard counterbore holders
• Carbon steel construction provides durability for general machining use
• Bright, uncoated finish — no coating to affect dimensional tolerances
• Lightweight at 0.05 pounds for easy handling and tool changes

Compatibility

Designed as an OEM-style replacement or standard shop pilot for counterbore tool sets accepting a 1/4 inch shank diameter and an 11/32 inch head diameter pilot.

Installation Notes

Counterbore pilots are installed and serviced by machinists and maintenance mechanics using standard lathe, drill press, or hand-drill setups. Before installing or swapping a pilot, ensure the spindle is fully stopped and the machine is powered down. Inspect the pilot shank and bore holder for wear or debris before seating the pilot to avoid misalignment. Do not force the pilot into an undersized holder, as this can damage the shank or compromise bore accuracy.
