M.a. Ford. 27206550 Chucking Reamer 0.0655 in Carbide

Product Description

The M.A. FORD. 27206550 is a solid carbide chucking reamer designed for precision hole finishing in light industrial and machining applications. Built to Series 272 specifications, it features a 0.0655-inch reamer diameter with a tight tolerance of +0.0001 to +0.0003 inches over nominal, making it suitable for close-tolerance bore finishing. The tool has an overall length of 1.5 inches, a straight-cylindrical shank, and four straight flutes with a left-hand spiral and right-hand cutting direction. It is installed in drill presses, CNC machining centers, and manual lathes by machinists and tool and die professionals requiring consistent, repeatable hole sizing.

This chucking reamer is suited for finish reaming small-diameter holes in ferrous and non-ferrous materials where dimensional accuracy is critical. The 0.0655-inch diameter falls within the 0.0500 to 0.0999-inch decimal inch range, making it appropriate for fine-pitch bore work in precision components, fixtures, and assemblies. The bright uncoated finish makes it easy to inspect for wear, and the solid carbide construction delivers rigidity in short-reach applications with a 3/8-inch flute length on a 1.5-inch overall body.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• Reamer diameter tolerance of +0.0001 to +0.0003 inches over nominal for close-tolerance bore finishing
• Four straight flutes with left-hand spiral and right-hand cutting direction
• Bright uncoated finish for easy wear inspection and broad material compatibility
• Straight-cylindrical shank for secure chuck or collet holding
• Series 272 designation, sold individually with a minimum order quantity of one

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill press chucks, CNC tool holders, and collet systems that accept a straight-cylindrical shank in the 0.0500 to 0.0999-inch diameter range.

Installation Notes

This tool is installed by machinists and precision metalworkers in accordance with standard machine shop practices. Always confirm spindle and chuck are fully de-energized and at rest before securing or removing the reamer. Ensure the shank is clean and fully seated in the collet or chuck before operation. Do not force the reamer into an undersized pilot hole; pre-drill or bore to the appropriate allowance before reaming to avoid tool breakage on this small-diameter solid carbide tool.
