M.a. Ford 27220900 Chucking Reamer 0.2090 in Solid Carbide

Product Description

The M.A. FORD 27220900 is a solid carbide chucking reamer designed to finish-ream precision holes to tight tolerances in metalworking and machining applications. Built to a 0.2090 inch diameter (Wire Size 4), it holds a reamer diameter tolerance of +0.0001 to +0.0003 inches, making it well suited for applications where hole geometry and surface finish are critical. The straight flute geometry and right-hand cutting direction provide clean, consistent material removal in through-holes and blind holes alike. Machinists and tool-and-die professionals install this reamer in CNC machining centers, knee mills, and drill presses using a standard chuck or collet setup.

This reamer is used in precision machining environments where a reamed hole must meet close dimensional tolerances for dowel pins, bushings, bearings, or press-fit components. With a 3.0 inch overall length and a 1 inch flute length, it is sized for shallow finishing passes in ferrous and non-ferrous materials. Its solid carbide construction provides the rigidity and wear resistance needed for production runs and hard materials. It is appropriate for both job-shop and production-floor use where repeatable hole sizing is required.

Key Features

• 0.2090 inch diameter (Wire Size 4) with a tolerance of +0.0001 to +0.0003 inches for precision fitment
• Solid carbide construction for superior rigidity and wear resistance compared to HSS alternatives
• Straight flute design with right-hand cutting and right-hand spiral direction
• Straight shank for direct chucking in collets, Jacobs chucks, or ER toolholders
• Uncoated finish suitable for use with cutting fluid across a range of workpiece materials
• 4-flute configuration provides balanced cutting action and good surface finish

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard straight-shank toolholders and chucks compatible with a 0.2090 inch diameter reamer. No specific machine or system compatibility data was provided by the manufacturer for this SKU.

Installation Notes

A licensed machinist or trained toolroom operator should install this reamer in a properly aligned spindle to avoid runout-induced oversize holes. Always secure the straight shank fully in the chuck or collet before operation, and verify spindle runout with a dial indicator when tolerance is critical. Apply appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Do not use this reamer as a drill — it is a finishing tool and must follow a drilled or bored hole that is already close to final diameter.
