M.a. Ford 27227700 Chucking Reamer Letter J Solid Carbide

Product Description

The M.A. FORD 27227700 is a solid carbide chucking reamer sized to Letter J, with a decimal diameter of 0.2770 inches. It is designed to finish-ream precision holes to tight tolerances in metalworking and machining applications. The tool features a straight flute geometry and right-hand cutting direction, making it suited for through-holes and blind holes where chip evacuation is controlled by the operator. With a diameter tolerance of +0.0001 to +0.0003 inches, this reamer delivers consistent, accurate bores. It is installed in a drill press, CNC machining center, or manual lathe chuck using its straight shank.

This reamer is used in production and job-shop machining environments where hole finish and dimensional accuracy are critical. Typical applications include reaming pilot holes in ferrous and non-ferrous metals, plastics, and similar machinable materials. The solid carbide construction provides superior rigidity and wear resistance compared to high-speed steel alternatives, making it a reliable choice for high-tolerance work. Machine shops, tool-and-die operations, and maintenance machinists working to tight fit specifications are the primary users of this tool.

Key Features

• Solid carbide construction for rigidity and extended tool life
• Letter J diameter (0.2770 inches) with tolerance of +0.0001 to +0.0003 inches
• Straight flute design with right-hand cutting direction
• 6-flute configuration for improved surface finish and material removal consistency
• Straight shank for direct chuck mounting on standard tooling
• Uncoated finish — suitable for use with cutting fluids where required

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard drill press chucks, CNC machining centers, and lathe tailstock setups accepting straight shank tooling in the applicable diameter range.

Installation Notes

Installation should be performed by a qualified machinist familiar with reaming operations and proper speeds and feeds for carbide tooling. Power down and de-energize the machine spindle completely before mounting or removing the tool from the chuck. Secure the straight shank firmly in the chuck to prevent slippage during operation. Always use an appropriate cutting fluid compatible with the workpiece material to protect the uncoated carbide edge and achieve the specified tolerance.
