Value Collection 08908485 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08908485 is a counterbore pilot used to guide counterboring tools during machining operations. It features a 0.75-inch head diameter and a 0.4375-inch shank diameter, providing a precise fit for aligning counterbore cutters on standard drill press and milling setups. Constructed from carbon steel with a bright, uncoated finish, this pilot delivers adequate hardness for general-purpose counterboring in ferrous and non-ferrous workpieces. Machinists, tool-and-die workers, and maintenance technicians install this type of pilot when accurate bore alignment and clean shoulder cuts are required.

This counterbore pilot is suited for use in machine shops, production facilities, and maintenance environments where counterbored holes are needed for socket head cap screws, dowel pins, or similar fasteners. It fits into standard counterbore tool holders and is appropriate for both manual and CNC-assisted drilling operations on a variety of metals and softer materials. Its uncoated finish makes it straightforward to inspect for wear during routine tool checks.

Key Features

• 0.75-inch head diameter for proper shoulder engagement in counterbored holes
• 0.4375-inch shank diameter for standard tool holder compatibility
• Carbon steel construction provides reliable hardness for general-purpose machining
• Bright, uncoated finish allows easy visual inspection of tool condition
• Lightweight at 0.31 pounds for easy handling and tool changes

Compatibility

Designed as a general-purpose counterbore pilot compatible with standard counterboring tool systems requiring a 0.75-inch head diameter and a 0.4375-inch shank diameter.

Installation Notes

This pilot is installed and serviced by machinists or maintenance technicians familiar with counterboring operations. Always power down and lock out the machine before inserting or removing the pilot from the tool holder. Inspect the pilot shank and head for wear, burrs, or damage before each use, as a worn pilot can cause misalignment and poor bore quality. Follow applicable shop safety standards and manufacturer tooling guidelines when setting up counterbore assemblies.
