Cleveland C25053 Chucking Reamer Wire Size 53 Hss

Product Description

The CLEVELAND C25053 is a straight-flute chucking reamer designed for precision hole finishing in metal and similar materials. Manufactured from high-speed steel with a bright uncoated finish, this reamer holds a wire gauge size 53, translating to a decimal diameter of 0.0595 inches. The straight shank allows direct mounting in drill chucks and collet holders. At 2.5 inches overall length with a 0.5-inch flute length, the C25053 is built for tight-tolerance reaming operations where consistent hole diameter and surface finish are required. Four right-hand cut flutes provide smooth chip evacuation and repeatable sizing performance.

This chucking reamer is suited for production and maintenance machining environments, including manual mills, CNC machining centers, drill presses, and lathes equipped with a drill chuck or collet. It is typically used on small-diameter through-holes and blind holes in steel, cast iron, aluminum, and brass. Wire size 53 is a common gauge in instrument-making, fixture work, and precision assembly applications where standard fractional or letter-size reamers do not cover the required diameter range.

Key Features

• Wire gauge size 53 with a decimal diameter of 0.0595 inches for precise small-bore finishing
• High-speed steel construction for durability across a range of workpiece materials
• Straight flute geometry for clean cutting action in through and shallow blind holes
• Four right-hand cut flutes for balanced chip load and smooth surface finish
• Straight shank compatible with standard drill chucks and collet systems
• Bright uncoated finish — no coating buildup that could affect dimensional accuracy on small diameters

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and straight-bore collet holders accepting straight-shank tooling in the applicable diameter range.

Installation Notes

Chucking reamers are installed by machinists or tool and die professionals. Secure the straight shank firmly in a drill chuck or collet before operation, and ensure the spindle is fully stopped before loading or removing the tool. Always ream at appropriate speeds and feeds for the workpiece material — excessive speed or feed rate will shorten tool life and degrade hole finish. Pre-drill the hole to within a few thousandths of the final diameter before reaming to avoid overloading the flutes.
