Value Collection 08905523 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08905523 is a counterbore pilot used to guide counterbore cutters during machining operations. The pilot fits a 1/4 inch shank and is sized for a 13/16 inch head diameter, making it suitable for standard counterbore setups on drill presses, milling machines, and hand-held drilling equipment. Constructed from carbon steel with a bright, uncoated finish, this pilot provides solid dimensional stability for general-purpose metal and woodworking applications. Machinists and fabricators rely on counterbore pilots to keep the cutter centered over an existing hole, producing clean, flat-bottomed recesses for socket head cap screws and similar fasteners.

This counterbore pilot is used in shop environments where precision recess cutting is required, including light manufacturing, maintenance and repair, and fabrication work. It is suited for use in ferrous and non-ferrous materials where a consistent counterbore depth and alignment are needed. The bright, uncoated carbon steel construction makes it appropriate for dry cutting conditions or applications where coolant compatibility is not a concern. Machinists, tool and die workers, and general shop technicians typically install and use this type of pilot as part of a counterbore cutter set.

Key Features

• 13/16 inch head diameter for standard counterbore cutter fitment
• 1/4 inch shank diameter for compatibility with common drill press and milling setups
• Carbon steel construction provides durability for general-purpose machining
• Bright, uncoated finish suited for dry cutting and low-wear applications
• Single-piece package quantity for individual tooling replacement or addition

Compatibility

Designed as an OEM-style replacement or supplemental pilot for counterbore cutter sets requiring a 1/4 inch shank diameter and a 13/16 inch head diameter.

Installation Notes

Installation is performed by qualified machinists or shop technicians. Always power down and lock out the machine before inserting or removing the counterbore pilot. Ensure the pilot shank seats fully and securely in the counterbore cutter body before resuming operation. Do not exceed the rated speed range for the cutter and pilot combination in use.
