Cleveland C46560 Counterbore Pilot 3/16 Inch Shank Hss

Product Description

The CLEVELAND C46560 is a counterbore pilot designed to guide counterbore cutters accurately during machining operations. With a 3/16-inch shank diameter and a 0.255-inch head diameter, this pilot fits standard counterbore tool bodies and ensures precise hole alignment. Constructed from high-speed steel with a bright, uncoated finish, it delivers reliable performance in general-purpose drilling and counterboring applications on ferrous and non-ferrous materials. Machinists and toolroom technicians rely on this pilot to maintain concentricity when creating recessed seats for socket head cap screws and similar fasteners.

This counterbore pilot is suited for use in machine shops, maintenance facilities, and production environments where accurate fastener seating is required. It fits counterbore tool bodies that accept a 3/16-inch shank and is appropriate for bench drill presses, knee mills, and CNC machining centers running moderate feed and speed parameters on common workpiece materials.

Key Features

• 3/16-inch shank diameter for secure tool body engagement
• 0.255-inch head diameter for accurate pilot guidance
• High-speed steel construction for durability in general-purpose machining
• Bright, uncoated finish suitable for use with cutting fluids
• Sold as a single unit for precise inventory control

Compatibility

Designed as a replacement or spare pilot for counterbore tool bodies that accept a 3/16-inch shank diameter. Verify head diameter and shank fit against your existing counterbore set before installation.

Installation Notes

Counterbore pilots are installed and serviced by machinists or toolroom technicians familiar with rotating cutting tool setups. Ensure the machine spindle is fully de-energized and locked out before changing pilots. Confirm the pilot shank is clean and free of burrs before seating it in the counterbore body to prevent runout. Follow applicable shop safety standards and machine manufacturer guidelines for tool-change procedures.
