M.a. Ford 27206400 Chucking Reamer 0.0640 in Solid Carbide

Product Description

The M.A. FORD 27206400 is a solid carbide chucking reamer engineered for precision hole finishing in metalworking and machining applications. Measuring 0.0640 inches in diameter with an overall length of 1.5 inches and a flute length of 0.375 inches, this reamer holds a tight diameter tolerance of +0.0001 to +0.0003 inches, making it suitable for close-tolerance bore work where dimensional accuracy is critical. The four-flute, right-hand cutting geometry on a straight-cylindrical shank is designed to be held in a drill press, CNC machining center, or lathe chuck. It is part of the M.A. FORD Series 272 line of small-diameter reamers.

This reamer is suited for light finishing passes on pre-drilled or pre-bored holes in ferrous and non-ferrous metals. Its sub-0.1-inch diameter places it firmly in the small-bore category, commonly used in instrument machining, mold and die work, aerospace components, and precision fixture fabrication. The bright, uncoated finish makes it straightforward to inspect for wear. Machinists and toolroom technicians working with tight tolerances on small bores will find this tool appropriate for their needs.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.0640 inch reamer diameter with tolerance of +0.0001 to +0.0003 inches
• Four straight flutes with right-hand cutting direction for consistent material removal
• Straight-cylindrical shank diameter of 0.0580 inches for secure chuck retention
• Bright, uncoated finish allows easy visual inspection of cutting edges
• Series 272 small-diameter design for sub-0.1-inch bore applications

Compatibility

Designed as an OEM-style replacement or direct tooling option for any machine setup requiring a straight-shank chucking reamer in the 0.0500 to 0.0999 inch diameter range, including drill presses, CNC machining centers, and manual lathes equipped with compatible collets or drill chucks.

Installation Notes

Installation and use should be performed by a qualified machinist or toolroom technician. Ensure the machine spindle and chuck are fully stopped and de-energized before loading or removing the reamer. Secure the straight-cylindrical shank firmly in a precision collet or drill chuck to minimize runout. Follow shop-standard feeds and speeds for solid carbide small-diameter reamers, and use appropriate cutting fluid where required by the workpiece material.
