Cleveland C46622 Counterbore Pilot 17/32 in Hss

Product Description

The CLEVELAND C46622 is a counterbore pilot designed for use with counterboring tools in metal fabrication and machining applications. It features a 17/32-inch head diameter and a 5/16-inch shank diameter, providing precise alignment and support during counterboring operations. Constructed from high-speed steel with a bright, uncoated finish, this pilot delivers the hardness and wear resistance needed for consistent performance in production and maintenance shop environments. Machinists and tool-and-die technicians rely on pilots like this to maintain bore concentricity and prevent tool wander during cutting.

This counterbore pilot is suited for metalworking environments where precise socket-head fastener seating or stepped-bore finishing is required. It is used in both manual machining and CNC setups where counterbore tool alignment is critical. The bright finish makes it well suited for general-purpose ferrous and non-ferrous material applications. It is sold individually and is appropriate for shop maintenance, production machining, and light manufacturing operations.

Key Features

• 17/32-inch head diameter for accurate counterbore alignment
• 5/16-inch shank diameter for secure tool holder engagement
• High-speed steel construction for hardness and wear resistance
• Bright, uncoated finish suitable for general-purpose metal cutting
• Sold as a single unit for targeted replacement or tool kit builds

Compatibility

Designed as a replacement or supplemental pilot for counterboring tools requiring a 17/32-inch head diameter and 5/16-inch shank diameter. Verify pilot head and shank dimensions against your counterbore body specification before installation.

Installation Notes

Installation of counterbore pilots is typically performed by machinists or maintenance technicians in a machine shop setting. Ensure the counterbore body and spindle are fully stopped and de-energized before inserting or removing the pilot. Confirm the shank seats fully and securely in the counterbore body before beginning any cutting operation. Do not force the pilot into an incompatible shank bore, as this can damage the pilot and affect bore concentricity.
