M.a. Ford 27203100 Chucking Reamer Size 68 Solid Carbide

Product Description

The M.A. FORD 27203100 is a solid carbide chucking reamer designed for precision hole finishing in machine shop and production environments. Sized at wire gauge 68 (0.0310 inches decimal diameter), this reamer is built for tight-tolerance work where hole quality and dimensional accuracy are critical. The four-flute, straight-flute geometry delivers smooth, controlled material removal on through-holes and blind holes in small-diameter applications. At 1.5 inches overall length with a 0.25-inch flute length, this is a compact tool suited for short-reach reaming operations. A licensed machinist or toolroom technician is the typical end user.

This chucking reamer fits production and job-shop CNC machining centers, manual mills, and drill presses where wire-gauge-size holes require finish reaming to tolerance. The straight shank allows direct mounting in standard precision chucks, collets, or floating reamer holders. Applications include precision bores in small mechanical components, instrument parts, and assemblies where hole diameter must hold within close limits. The reamer tolerance of plus 0.0001 to plus 0.0003 inches supports H7 and similar close-fit standards commonly required in mechanical assembly work.

Key Features

• Solid carbide construction for wear resistance and dimensional stability in hard or abrasive workpiece materials
• Wire gauge 68 diameter (0.0310 inches decimal) for precision small-bore finishing
• Four straight flutes provide consistent chip evacuation and surface finish in short-flute applications
• Right-hand cut, right-hand spiral direction for standard machine rotation
• Reamer diameter tolerance of plus 0.0001 to plus 0.0003 inches for close-tolerance hole finishing
• Uncoated carbide substrate suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard precision chucks, collets, and floating reamer holders on CNC machining centers, manual mills, and drill presses accepting straight-shank tooling.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist or toolroom technician familiar with reaming operations. Secure the straight shank in a precision collet or floating reamer holder to minimize runout before use. Ensure the spindle and workpiece fixture are fully secured and the machine is at a safe, controlled speed appropriate for carbide reaming before starting the cut. Do not use this tool for drilling or use feed rates beyond what the workpiece material and hole condition support, as carbide tools are brittle and can fracture under side load or shock.
