M.a. Ford 27203350 Chucking Reamer 0.85mm Solid Carbide

Product Description

The M.A. FORD 27203350 is a solid carbide chucking reamer engineered for precision bore finishing in metalworking applications. With a 0.85 mm reamer diameter and a tight tolerance of +0.004 to +0.008 mm over nominal, this tool delivers consistent, repeatable hole sizing in one pass. The straight, right-hand cutting geometry across 4 flutes produces smooth finishes at small diameters where rigidity is critical. Machinist and tool-and-die professionals install this reamer in CNC machining centers and manual drilling equipment via a straight-cylindrical shank. The bright, uncoated carbide surface suits dry cutting and standard coolant environments alike.

This reamer is designed for applications requiring precise bore finishing at sub-1 mm diameters, typical in precision parts manufacturing, mold making, medical device machining, and aerospace component work. Its 6.50 mm flute length and 38.00 mm overall length make it well suited for shallow-to-moderate depth holes in close-tolerance work. It falls within Series 272 of the M.A. FORD product line and is sized for use in collet chucks or precision drill chucks that accommodate its straight-cylindrical shank profile.

Key Features

• Solid carbide construction for rigidity and wear resistance at small diameters
• 0.85 mm reamer diameter with +0.004 to +0.008 mm tolerance for controlled oversize finishing
• 4 straight flutes, right-hand cutting direction for standard spindle operation
• Bright, uncoated finish suitable for a wide range of workpiece materials
• Straight-cylindrical shank for use in collet chucks and precision drill chucks
• Compact 38.00 mm overall length with 6.50 mm flute length for shallow precision bores

Compatibility

Designed as an OEM-style precision chucking reamer for use in CNC machining centers, drill presses, and lathes equipped with collet chucks or precision drill chucks capable of holding a straight-cylindrical shank at sub-1 mm diameter tooling.

Installation Notes

This tool is installed and operated by machinists and toolmakers in machine shop environments. Before tool changes, ensure the spindle is fully stopped and all machine guards are in place per shop safety procedures. Secure the straight-cylindrical shank firmly in a precision collet or drill chuck to minimize runout, which is especially critical at this diameter. Do not exceed the recommended feed and speed parameters for solid carbide tooling at this size to avoid tool breakage.
