Cleveland C25262 Chucking Reamer Wire Size 27 Hss

Product Description

The CLEVELAND C25262 is a straight-flute chucking reamer ground to a wire gauge No. 27 diameter of 0.1440 inches. Built from high-speed steel (HSS) with a bright, uncoated finish, this tool is designed for precision hole finishing in a wide range of ferrous and non-ferrous materials. It features six flutes and a right-hand cutting direction, producing a clean, accurate bore in a single pass. With an overall length of 4 inches and a 1-inch flute length, the C25262 is sized for use in drill presses, lathes, and CNC machining centers where repeatable hole tolerances are required. It is the correct choice for machinists and toolroom professionals working in the No. 27 wire gauge range.

This reamer is suited for production and repair machining environments requiring tight bore tolerances in the 0.1000 to 0.1499 inch diameter range. The straight shank allows direct mounting in standard drill chucks, collets, or floating reamer holders without modification. Typical applications include through-hole and blind-hole finishing in metal fabrication, maintenance machining, and precision assembly operations where drilled holes must be brought to final size and finish.

Key Features

• Wire gauge No. 27 cutting diameter: 0.1440 inches for precise hole finishing
• High-speed steel construction for durability across a range of workpiece materials
• Six straight flutes with right-hand cut for smooth material removal
• Bright uncoated finish suitable for general-purpose machining applications
• Straight shank compatible with standard drill chucks and collet holders
• Compact 4-inch overall length for use in confined setups and standard machine spindles

Compatibility

Designed as an OEM-style replacement and standard chucking reamer for machine tools accepting straight-shank tooling in the No. 27 wire gauge diameter class.

Installation Notes

Chucking reamers are installed and operated by qualified machinists. Secure the straight shank firmly in a drill chuck, collet, or floating holder before operation, and confirm the machine spindle is fully stopped before tool changes. Use appropriate cutting fluid for the workpiece material to extend tool life and achieve optimal surface finish. Do not use a reamer to remove excess stock; pre-drill the hole to within the recommended allowance before reaming to final size.
