M.a. Ford 27208900 Chucking Reamer Wire 43 Solid Carbide

Product Description

The M.A. FORD 27208900 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to wire gauge size 43, this reamer produces a finished bore diameter of 0.0890 inches with a tolerance of +0.0001 to +0.0003 inches, making it well-suited for work where dimensional accuracy is critical. The four-flute, right-hand cut configuration with a straight flute geometry provides stable, consistent material removal. The overall length is 2 inches with a flute length of 0.5 inches. Machinists and tool-and-die professionals install this reamer in drill presses, lathes, and CNC machining centers using a standard straight shank chuck setup.

This reamer is appropriate for small-diameter finishing operations in metalworking environments, including production shops, toolrooms, and job shops handling precision components. It is part of the M.A. FORD Series 272 line of solid carbide chucking reamers. The uncoated solid carbide construction is suitable for ferrous and non-ferrous workpiece materials where a bare carbide cutting edge is preferred. No coolant-through capability is present, so flood or mist coolant applied externally is typical practice when machining harder materials.

Key Features

• Wire size 43 reamer diameter of 0.0890 inches for precise small-bore finishing
• Solid carbide construction for rigidity and wear resistance in precision applications
• Four straight flutes with right-hand cut and right-hand spiral direction
• Tight diameter tolerance of +0.0001 to +0.0003 inches for consistent hole sizing
• Straight shank for direct chuck mounting on standard machine tool setups
• Uncoated finish suitable for applications where coating is not required or preferred

Compatibility

Designed as an OEM-style solid carbide chucking reamer in the M.A. FORD Series 272 line, compatible with standard straight-shank chuck holders on drill presses, lathes, and CNC machining centers accepting the 0.0890-inch shank diameter.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with reaming procedures and toolroom safety practices. Ensure the machine spindle is fully stopped and locked out before mounting or removing the reamer from the chuck. The reamer should be run at appropriate speeds and feeds for the workpiece material to avoid deflection or tool breakage given the small diameter. External coolant or cutting fluid is recommended when reaming harder materials, as this tool does not include coolant-through capability.
