Cleveland C25516 Chucking Reamer

The Cleveland C25516 is a high-speed steel chucking reamer designed for precision hole finishing in metalworking applications. Its straight shank fits standard chucks on drill presses, lathes, or milling machines. Machinists and maintenance technicians use it to bring drilled holes to exact size and improved surface finish.

Bright uncoated finish and oversized diameter

The bright, uncoated surface provides a clean cutting action without coating buildup, suitable for general-purpose ferrous and non-ferrous materials. The .2510 inch oversized diameter allows the tool to cut slightly larger than a standard quarter-inch nominal size, accommodating specific fit requirements or subsequent plating processes.

Straight shank limits automatic tool changer

The straight shank design requires a three-jaw chuck or collet for secure holding, which prevents direct use in machine spindles that rely on taper-lock or quick-change interfaces. The high-speed steel construction offers good wear resistance but lacks the extreme hardness of carbide, limiting effectiveness in very abrasive or hardened workpieces.

Questions about this item

When will the .2510" HSS cutting edges need resharpening or replacement?

Resharpen the HSS flutes when hole finish degrades or feed force rises; the bright uncoated surface can be reground multiple times before the shank reaches minimum diameter.

What limits continuous reaming in a single setup?

Chip evacuation in the straight flutes becomes the bottleneck — deep or blind holes pack swarf and force a pause to clear the tool.

How much heat builds up in the tool body during an all-day production run?

The uncoated HSS body conducts heat into the workpiece and coolant; with steady flood lubrication the shank stays warm but not hot enough to affect holder grip.
