M.a. Ford. 27235940 Chucking Reamer 23/64 in Solid Carbide

Product Description

The M.A. FORD. 27235940 is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a diameter of 23/64 inches (0.3594 inches decimal) and a tight tolerance of +0.0001 to +0.0003 inches, this reamer delivers accurate, repeatable bore sizing in production and job-shop environments. The 6-flute straight configuration and right-hand cutting direction provide smooth material removal and consistent surface finish. Overall length is 3.5 inches with a 1.25-inch flute length. Machinists and toolroom professionals specify solid carbide construction for its rigidity and wear resistance, particularly in harder workpiece materials.

This chucking reamer is suited for finishing pre-drilled or bored holes to close tolerances in ferrous and non-ferrous materials. The straight shank mounts directly in drill chucks, collet chucks, or floating holders on CNC machining centers, manual mills, and drill presses. The uncoated solid carbide body is a common choice when machining aluminum, brass, cast iron, and medium-hardness steels where a precise H7 or similar fit is required. It is typically used as the final sizing operation after a roughing drill or boring pass has established the hole location.

Key Features

• Solid carbide construction for high rigidity and extended tool life in production environments
• Diameter tolerance of +0.0001 to +0.0003 inches for close-tolerance bore finishing
• 6-flute straight configuration provides consistent surface finish and chip clearance
• Right-hand spiral direction with right-hand cutting for standard CNC and manual spindle rotation
• Straight shank compatible with drill chucks, ER collets, and floating reamer holders
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide chucking reamer for applications requiring a 23/64-inch finished bore diameter. Part of the M.A. FORD. Series 272 reamer line.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations and machine tool safety. Ensure the spindle and workpiece are securely fixtured and the machine is at the correct RPM and feed rate for solid carbide tooling before starting the cut. Use an appropriate cutting fluid or coolant to extend tool life and maintain bore quality. Do not run a chucking reamer in reverse rotation, as this will damage the cutting edges.
