Cleveland Counterbore Pilot

The Cleveland C46572 is a high-speed steel pilot designed for counterboring operations. It features a bright uncoated finish and a 0.188 inch diameter. The overall length measures 2.000 inches. This accessory fits compatible counterbore tools for precision hole preparation.

Suited for machinists needing a 5/16 inch pilot

This pilot suits workshops running counterbore setups that accept a 5/16 inch shank. It will not work for builders who need a different pilot diameter or a coated cutting surface. Buyers requiring a complete counterbore assembly should look at a full tool kit instead.

Bright finish aids chip visibility

The uncoated bright finish helps operators see chip formation during cutting. No lubricant or coating is pre-applied so users can apply their preferred cutting fluid. The high-speed steel construction allows resharpening for extended service life. Orders of 75 dollars or more ship free from the supplier.
