Value Collection 08909707 Counterbore Pilot Carbon Steel

Product Description

The VALUE COLLECTION 08909707 is a counterbore pilot used to guide counterboring operations and keep the cutting tool centered over a pre-drilled hole. The pilot fits a 1/2-inch shank and is designed to work with counterbore sets where precise alignment is required. Constructed from carbon steel with a bright, uncoated finish, it delivers adequate hardness for general-purpose machining applications. Machinists, tool-and-die technicians, and maintenance professionals use this pilot when counterboring bolt clearance holes, seat surfaces, or fastener recesses in metal and other rigid materials.

This counterbore pilot is suited for use in machine shops, maintenance facilities, and production environments where standard counterboring operations are performed. It is compatible with counterbore tools that accept a 1/2-inch pilot shank. The 1-1/8-inch head diameter makes it appropriate for countersinking or guiding cuts around holes requiring a larger bearing surface. It is sold as a single unit.

Key Features

• 1-1/8-inch head diameter for broad bearing surface during counterboring
• 1/2-inch shank diameter for standard counterbore tool compatibility
• Carbon steel construction provides adequate hardness for general machining
• Bright, uncoated finish — no additional surface treatment that could affect tolerances
• Lightweight at 0.5 pounds for easy handling and tool-change efficiency

Compatibility

Designed for use with counterbore tools that accept a 1/2-inch pilot shank diameter. Suitable for general-purpose counterboring in production and maintenance machining setups.

Installation Notes

Installation and use of this counterbore pilot should be performed by a qualified machinist or maintenance technician familiar with counterboring operations. Ensure the machine spindle is fully stopped and power is locked out before changing or seating the pilot. Verify the pilot shank seats securely in the counterbore body before beginning any cutting operation. Follow standard shop safety procedures and applicable workplace machining guidelines when in use.
