M.a. Ford. 27205400A Chucking Reamer 0.054 in Solid Carbide

Product Description

The M.A. FORD. 27205400A is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. Built to Series 272 standards, it produces a 0.0540-inch diameter bore with a tight tolerance of +0.0001 to +0.0003 inches, making it suitable for close-tolerance fitment applications. The four-flute, straight-flute geometry runs right-hand cutting with an ALtima coating for extended tool life. With a 1-1/2-inch overall length and 3/8-inch flute length, this reamer fits compact tooling setups. It is sized for use in CNC machining centers, drill presses, and manual lathes where repeatable bore accuracy is required.

This chucking reamer is intended for machinists and toolroom professionals working with small-diameter precision bores in ferrous and non-ferrous materials. The straight-cylindrical shank, measuring 0.0460 inches in diameter, seats directly into standard collets or chucks without adaptation. At 0.0540 inches diameter, this tool addresses the 0.0500 to 0.0999-inch reamer diameter range and is classified as a modified standard item. It is well suited for production runs requiring consistent bore sizing across multiple workpieces.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• ALtima coating for improved surface finish and tool longevity
• Four straight flutes with right-hand cutting direction
• Diameter tolerance of +0.0001 to +0.0003 inches for close-tolerance bore finishing
• Straight-cylindrical shank compatible with standard collet and chuck systems
• Compact 1-1/2-inch overall length suits tight machine clearances

Compatibility

Designed as an OEM-style precision reamer for use in CNC machining centers, drill presses, and manual lathes accepting straight-cylindrical shank tooling in the 0.0500 to 0.0999-inch diameter range.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with small-diameter cutting tools. Ensure the machine spindle is fully stopped and power is locked out before loading or removing the tool from the collet or chuck. Use appropriate cutting fluid for the workpiece material, and confirm runout is within acceptable limits before engaging the cut to avoid tool breakage at this diameter. Note that this item is a modified standard product and is non-returnable and non-cancelable once ordered.
