M.a. Ford 27209850 Chucking Reamer 0.0985 in Solid Carbide

Product Description

The M.A. FORD 27209850 is a solid carbide chucking reamer designed for precision hole finishing in metal and other rigid materials. It carries a reamer diameter of 0.0985 inches with a tight tolerance of +0.0001 to +0.0003 inches, making it well suited for applications where bore accuracy and surface finish are critical. The overall length is 2.25 inches with a flute length of 0.625 inches. The straight-cylindrical shank seats directly into standard drill chucks or collet holders. With 4 straight flutes and right-hand cutting direction, this reamer is run by machinists and tool-and-die professionals on drill presses, lathes, and milling machines.

This reamer fits within the Series 272 product family and is sized for small-diameter bore work in the 0.0500 to 0.0999 inch diameter range. It is well matched to precision machining environments including production shops, toolrooms, and maintenance machining operations where tight hole tolerances are required. The bright, uncoated carbide finish makes it appropriate for use on ferrous and non-ferrous workpieces where coating interaction is a concern. No coolant-through capability means it is intended for use with external coolant application or dry cutting where permitted by the workpiece material.

Key Features

• Solid carbide construction for rigidity and wear resistance in small-diameter reaming
• Diameter tolerance of +0.0001 to +0.0003 inches for precise bore sizing
• 4 straight flutes with right-hand cutting direction for smooth, consistent material removal
• Bright, uncoated finish suitable for a broad range of workpiece materials
• Straight-cylindrical shank for direct chucking in standard holders
• Series 272 design optimized for the 0.0500 to 0.0999 inch diameter range

Compatibility

Designed as a Series 272 solid carbide chucking reamer for use in standard drill chucks and collet holders that accept a straight-cylindrical shank at the 0.0985 inch diameter specification.

Installation Notes

This tool is installed and operated by machinists using drill presses, CNC machining centers, lathes, or manual milling machines. Secure the shank fully in a clean, properly sized chuck or collet to prevent runout. Ensure the spindle and workpiece are properly aligned before cutting to maintain tolerance. Apply appropriate cutting fluid externally as needed based on workpiece material, since this reamer does not support coolant-through delivery.
