Value Collection 08905440 Counterbore Pilot 11/16 in Head

Product Description

The Value Collection 08905440 is a counterbore pilot used to guide counterboring tools during machining operations. It centers the cutting tool over a pre-drilled hole to produce a flat-bottomed recess for socket-head fasteners, dowel pins, or similar hardware. The pilot features an 11/16-inch head diameter and a 1/4-inch shank diameter, making it compatible with standard counterbore sets and tool holders of that shank size. Constructed from carbon steel with a bright, uncoated finish, it is suited for general-purpose shop and field machining work performed by machinists, maintenance technicians, and trade professionals.

This counterbore pilot is used in metalworking and maintenance applications where a precisely guided counterbore cut is required. It is appropriate for use in manual mills, drill presses, and hand-held drilling setups where shank-guided piloting is needed. The bright finish leaves the steel uncoated, which is typical for pilots used in dry cutting or where lubrication is applied at the point of use. Sold individually, it suits single-replacement or low-volume shop needs.

Key Features

Compatibility

Designed as a replacement or spare pilot for counterbore sets and tool holders accepting a 1/4-inch shank with an 11/16-inch head diameter. No specific tool brand or model compatibility was stated by the manufacturer.

Installation Notes

Installation and use of this pilot should be performed by a qualified machinist or maintenance technician familiar with counterboring operations. Secure the pilot firmly in the counterbore body before beginning any cut, and ensure the host machine is powered down and locked out before changing pilots. Apply an appropriate cutting fluid for the material being machined to extend pilot life and improve cut quality.
