Cleveland C91715 Counterbore Application
The Cleveland C91715 counterbore is a pneumatic accessory designed for precision counterboring tasks in workshop environments. It suits machinists and technicians who require a dedicated tool for creating flat-bottomed holes with a built-in pilot for alignment. The bright finish high-speed steel construction supports general-purpose metalworking applications. This item is supplied new and ships directly from the manufacturer.
Sustained Cutting Performance
Under sustained load the high-speed steel body maintains hardness and resists heat buildup during extended drilling cycles. The built-in pilot keeps the cutter centred, reducing wander and vibration when the tool remains engaged for longer periods. Consistent feed rates help preserve the cutting edges and surface finish on the workpiece. The 7.000 inch overall length provides reach for deeper counterbore operations without deflection.
Pre-Order Compatibility Checks
Verify that your pneumatic system delivers the required air pressure and flow for a .500 inch diameter cutting tool before ordering. Confirm the 7/16 inch pilot size matches the pre-drilled hole diameter in your workpiece to ensure proper guidance. Ensure your tool holder or chuck accommodates the shank dimensions implied by the cutter specifications. Check that the workpiece material is suitable for high-speed steel counterboring.

Questions about this item
How much heat does the 7.000" counterbore generate during continuous pneumatic use?
The high-speed steel body dissipates cutting heat efficiently; no external cooling is required for normal all-day operation.
What shank size must my drill or driver accept to run the .500" diameter counterbore?
A standard 1/2" (0.500") chuck or collet is needed to hold the tool securely.
Will the C91715 counterbore fit older fractional-inch pilot holes in my existing jigs?
Yes, the 7/16" built-in pilot matches common fractional-inch patterns used in legacy fixtures.
