M.a. Ford. 27208500A Chucking Reamer 0.0850 in Solid Carbide

Product Description

The M.A. FORD. 27208500A is a solid carbide chucking reamer designed for precision hole finishing in machining applications. With a reamer diameter of 0.0850 inches and a tight tolerance of +0.0001 to +0.0003 inches, this tool delivers accurate, repeatable bore sizing in small-diameter work. The overall length is 2 inches with a 1/2-inch flute length, making it well suited for shallow-hole reaming operations. The ALtima coating provides surface hardness and wear resistance. It features a straight-cylindrical shank for standard chuck mounting and right-hand cutting with 4 straight flutes. Machinists and tool-and-die professionals working in tight-tolerance production environments are the primary users of this tool.

This reamer is intended for small-diameter precision reaming in metalworking and machining operations. It falls within M.A. FORD. Series 272 and is classified as a modified standard item. Typical applications include finishing pre-drilled holes to tight tolerances in ferrous and non-ferrous metals. The 0.0850-inch diameter places it in the 0.0500 to 0.0999 inch range, making it appropriate for fine-bore work in jigs, fixtures, and close-tolerance component manufacturing. It is sold individually with a minimum order quantity of 1.

• Solid carbide construction for rigidity and wear resistance in precision reaming
• ALtima coating for improved surface hardness and extended tool life
• Diameter tolerance of +0.0001 to +0.0003 inches for tight, repeatable bore sizing
• 4 straight flutes with right-hand cutting direction for smooth material removal
• Straight-cylindrical shank compatible with standard chucks and collets
• Compact 2-inch OAL with 1/2-inch flute length for shallow-hole applications

Compatibility

Designed as an OEM-style precision chucking reamer within M.A. FORD. Series 272, suitable for use in CNC machining centers, manual mills, and drill presses equipped with standard straight-shank chuck or collet tooling accepting a straight-cylindrical shank.

Installation Notes

Installation and use of this reamer should be performed by qualified machinists familiar with small-diameter precision tooling. Secure the straight-cylindrical shank firmly in a compatible chuck or collet before operation and verify runout before cutting. Use appropriate cutting fluid or lubricant for the workpiece material to maximize tool life and surface finish. This item is designated as non-returnable and non-cancelable once ordered.
