Cleveland C46529 Counterbore Pilot 5/32 Inch Hss

Product Description

The CLEVELAND C46529 is a counterbore pilot designed for use with counterbore cutters in precision machining and metalworking applications. The pilot features a 5/32 inch head diameter and a 5/32 inch shank diameter, machined from high-speed steel (HSS) for durability under repeated use. The bright, uncoated finish maintains tight tolerances straight from the factory. This pilot guides the counterbore cutter concentrically over a pre-drilled hole, ensuring accurate seat depth and alignment for fastener heads, bolts, and socket cap screws. It is a direct-fit accessory used by machinists and maintenance technicians working in job shops, production environments, and industrial maintenance settings.

This counterbore pilot is suited for use in ferrous and non-ferrous metals where a properly sized 5/32 inch shank counterbore setup is required. Typical applications include creating flat-bottomed recesses for socket head cap screws and similar fasteners in steel, aluminum, and cast iron workpieces. The high-speed steel construction holds up well in general-purpose machining where carbide tooling is not required. Sold individually as a single unit.

Key Features

• 5/32 inch head diameter for precise counterbore seat alignment
• 5/32 inch shank diameter for standard counterbore tool holders
• High-speed steel construction for durability in general-purpose machining
• Bright, uncoated finish maintains dimensional accuracy out of the box
• Single-piece package for individual replacement or tooling expansion

Compatibility

Designed as a replacement or supplemental pilot for counterbore cutter sets requiring a 5/32 inch shank and head diameter pilot. Confirm pilot shank diameter matches the counterbore tool holder before installation.

Installation Notes

Installation is performed by qualified machinists or maintenance technicians. Secure the pilot firmly in the counterbore tool holder before use and verify it seats without play. Ensure the workpiece is clamped and the machine is at a full stop before changing or inspecting pilots. Do not use damaged or worn pilots, as runout will affect counterbore concentricity and fastener seating.
