M.a. Ford 27205200 Chucking Reamer Wire 55 Solid Carbide

Product Description

The M.A. FORD 27205200 is a solid carbide chucking reamer designed to finish-ream precision holes to a wire size 55 diameter of 0.0520 inches. Built from solid carbide throughout, it delivers the rigidity and wear resistance required for tight-tolerance work in hardened materials, alloys, and other demanding workpiece materials. The four-flute straight configuration produces a clean, accurate bore with a diameter tolerance of +0.0001 to +0.0003 inches, making it suitable for applications where hole finish and dimensional accuracy are critical. Licensed machinists and toolroom technicians are the primary users of this style of reamer.

This reamer is intended for use in machine tool spindles, CNC machining centers, drill presses, and manual mills where the shank is held in a collet chuck or drill chuck. The straight shank provides straightforward tool holding without the need for specialized adapters. With an overall length of 1.5 inches and a flute length of 0.375 inches, this tool is best suited for shallow through-holes and blind holes in light industrial and precision machining environments. It is sold individually and is appropriate for low-volume toolroom use as well as production applications requiring consistent hole geometry.

Key Features

• Solid carbide construction provides superior hardness and wear resistance compared to high-speed steel alternatives
• Wire size 55 designation corresponds to a decimal diameter of 0.0520 inches
• Four straight flutes with right-hand cutting direction for standard spindle rotation
• Diameter tolerance of +0.0001 to +0.0003 inches supports tight-fit hole requirements
• Straight shank compatible with standard collet chucks and drill chucks
• Uncoated finish allows for straightforward resharpening when needed

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard machine tool spindles accepting straight-shank tooling in the applicable diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and workpiece fixture are fully secured before starting the cut. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Solid carbide tooling is brittle and should never be used to hand-ream or force through misaligned holes, as this risks chipping or fracturing the tool.
