M.a. Ford 27212450A Chucking Reamer 0.1245 in Solid Carbide

Product Description

The M.A. FORD 27212450A is a solid carbide chucking reamer designed for precision hole finishing in machining operations. With a reamer diameter of 0.1245 inches and a diameter tolerance of +0.0001 to +0.0003 inches, this tool holds tight sizing for accurate fits in drilled or bored holes. The 4-flute, straight-flute geometry with right-hand cutting direction provides clean, consistent material removal. An ALtima coating adds surface hardness and wear resistance for extended tool life. Overall length is 2.25 inches with a 5/8-inch flute length. It mounts via a straight-cylindrical shank for use in standard chucks and collets. This reamer is intended for skilled machinists and tool-and-die professionals working to close tolerances.

The 27212450A is suited for finish-reaming small-diameter holes in ferrous and non-ferrous materials in both manual and CNC machine tool setups. Its compact overall length and small diameter make it appropriate for precision work in tight part geometries. This is a modified standard item from the M.A. FORD Series 272 line. Note that this item is non-returnable and non-cancelable once ordered.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with precision hole-finishing operations. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before engaging the workpiece. Ensure the machine spindle is fully stopped and the machine is de-energized before mounting or removing the tool. Do not exceed the tool manufacturer's recommended speeds and feeds for the workpiece material and reamer diameter.
