Value Collection 08908824 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08908824 is a counterbore pilot used to guide counterbore cutters during precision boring operations on metal workpieces. The pilot features a 1.5-inch head diameter and a 0.4375-inch shank diameter, sized to maintain concentricity and alignment when cutting counterbored recesses for fastener seating. Constructed from carbon steel with a bright, uncoated finish, this pilot is suited for general machining work in fabrication and maintenance environments. Licensed machinists and tool-and-die professionals use this type of pilot to ensure accurate, repeatable counterbore depth and location across production and repair applications.

This counterbore pilot is appropriate for use in metalworking shops, maintenance facilities, and industrial fabrication settings where counterbored holes are required for socket head cap screws, bolts, or similar fasteners. It fits standard counterbore tool holders that accept a 0.4375-inch shank. The bright finish indicates no secondary coating treatment, making it straightforward to inspect for wear during service intervals.

Key Features

• 1.5-inch head diameter for guiding counterbore cutters on standard fastener recesses
• 0.4375-inch shank diameter for compatibility with matching counterbore holders
• Carbon steel construction provides adequate hardness for general metalworking use
• Bright, uncoated finish simplifies visual inspection and requires no additional preparation before use
• Single-piece packaging — one pilot per unit as shipped

Compatibility

Designed as a replacement or spare counterbore pilot for use with standard counterbore cutter sets accepting a 0.4375-inch shank and a 1.5-inch head diameter.

Installation Notes

Installation of counterbore pilots should be performed by qualified machinists following standard machine shop safety procedures. Ensure the machine spindle is fully powered down and locked out before inserting or removing the pilot from the counterbore tool holder. Verify shank diameter clearance and head diameter match the counterbore cutter set before use. Inspect the pilot for wear or damage before each use to prevent misalignment during cutting operations.
