M.a. Ford. 27203300 Chucking Reamer 0.0330 in Solid Carbide

Product Description

The M.A. FORD. 27203300 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to Series 272, this reamer carries a wire gauge size of 66 and a decimal diameter of 0.0330 inches, with a reamer diameter tolerance of +0.0001 to +0.0003 inches. The straight flute geometry and right-hand cut make it well-suited for through-hole reaming in a variety of materials. With a 4-flute configuration and uncoated solid carbide construction, it delivers consistent sizing and surface finish in production and toolroom environments where dimensional accuracy is critical.

This reamer is intended for use in CNC machining centers, manual mills, and drill presses where small-diameter precision holes require finishing to close tolerances. The straight shank allows direct chucking in standard collets or drill chucks. With an overall length of 1.5 inches and a flute length of 0.25 inches, the 27203300 is suited for shallow finishing passes in thin workpieces or near-surface bore locations. Machinists and toolroom technicians working with ferrous and non-ferrous materials in aerospace, medical device, and general precision manufacturing applications will find this tool appropriate for high-accuracy reaming at sub-0.05 inch diameters.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small diameters
• Wire gauge size 66 with decimal diameter of 0.0330 inches for precise sizing
• Diameter tolerance of +0.0001 to +0.0003 inches ensures tight hole control
• 4-flute straight geometry supports clean, consistent material removal
• Right-hand cut with straight shank for standard collet or chuck mounting
• 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 wire gauge 66 diameter in Series 272 tooling setups. No specific machine model compatibility was provided in the product data.

Installation Notes

Installation and use of this reamer should be performed by a qualified machinist familiar with small-diameter tooling. Ensure the machine spindle, collet, and chuck are clean and properly torqued before seating the straight shank. Do not exceed the recommended feed and speed parameters for solid carbide at this diameter, as small carbide tools are susceptible to breakage under side load or interrupted cuts. Apply an appropriate cutting fluid to extend tool life and maintain hole finish quality.
