Value Collection 08907727 Counterbore Pilot

Product Description

The VALUE COLLECTION 08907727 is a counterbore pilot used to guide counterbore cutting tools during machining operations. The pilot ensures accurate alignment of the counterbore with a pre-drilled hole, preventing tool walk and producing clean, concentric seats for socket head cap screws and similar fasteners. It features a 1-3/16 inch head diameter and a 3/8 inch shank diameter, machined from carbon steel with a bright uncoated finish. This type of pilot is a standard replacement and accessory component used in metal fabrication, maintenance machining, and mechanical assembly work.

Counterbore pilots are used in machine shops, maintenance facilities, and on-site fabrication work wherever counterbored fastener seats are required. This pilot is appropriate for use in drill press, milling machine, and hand-held drill applications where repeatability and concentricity are required. The bright uncoated carbon steel construction suits general-purpose dry or lightly lubricated cutting environments.

Key Features

• 1-3/16 inch head diameter for proper counterbore guidance
• 3/8 inch shank diameter for standard tool holder compatibility
• Carbon steel construction for general-purpose machining durability
• Bright uncoated finish suitable for dry and light-lubrication applications
• Sold individually as a single-piece unit

Compatibility

Designed as a replacement or spare counterbore pilot for standard counterbore tool sets accepting a 3/8 inch shank diameter and a 1-3/16 inch head diameter.

Installation Notes

Installation of counterbore pilots is typically performed by machinists or maintenance technicians. Ensure the spindle, drill press, or milling machine is fully powered down and secured before inserting or removing the pilot. Verify that the shank is fully seated and secured in the tool holder before beginning any cutting operation. Do not force the pilot into an undersized or damaged socket.
