Value Collection 08905184 Counterbore Pilot 9/32 in Head

Product Description

The VALUE COLLECTION 08905184 is a counterbore pilot used to guide counterbore cutters during machining operations. The pilot fits into a pre-drilled hole to center the counterbore tool, ensuring accurate seat depth and alignment for fastener heads. It features a 9/32-inch head diameter and a 1/4-inch shank diameter, machined from carbon steel with a bright, uncoated finish. Machinists and tool-and-die technicians use this type of pilot in drill press, mill, and hand-drill applications where consistent counterbore alignment is required. The carbon steel construction provides sufficient hardness for use in wood, plastic, and light metalworking applications.

This counterbore pilot is suited for general shop and field use where a 1/4-inch shank counterbore tool is in service. Typical applications include cabinetry, fixture fabrication, and light structural assembly where fastener heads must sit flush or recessed. It is sold individually and is appropriate for professional machine shops, maintenance technicians, and skilled tradespeople who require a reliable pilot for repeat counterbore operations.

Key Features

• 9/32-inch head diameter for precise counterbore seat alignment
• 1/4-inch shank diameter for standard counterbore tool compatibility
• Carbon steel construction for durability across wood, plastic, and light metal substrates
• Bright, uncoated finish — no coating to add dimensional variation
• Sold as a single unit for individual replacement or tool kit builds

Compatibility

Designed as a replacement or spare pilot for counterbore tools accepting a 1/4-inch shank and a 9/32-inch head diameter. Confirm shank and head dimensions against your existing counterbore set before ordering.

Installation Notes

Installation is performed by machinists or skilled tradespeople familiar with counterboring operations. Ensure the counterbore tool is fully secured in the spindle and the workpiece is clamped before inserting the pilot. Do not force the pilot into an undersized pilot hole; the pre-drilled hole must match the head diameter for proper guidance. Follow standard shop safety practices, including eye protection, when operating rotary cutting tools.
