M.a. Ford. 27218900 Chucking Reamer 0.1890 in Solid Carbide

Product Description

The M.A. FORD. 27218900 is a solid carbide chucking reamer designed for precision hole finishing in metal and composite workpieces. Built to wire gauge size 12 with a reamer diameter of 0.1890 inches, it holds a tight tolerance of +0.0001 to +0.0003 inches, making it suited for applications where bore accuracy and surface finish are critical. The four-flute, straight-flute geometry provides smooth, consistent cutting action during right-hand rotation. Machining professionals and tool-room technicians install this reamer in CNC machining centers, drill presses, and manual lathes where controlled stock removal and repeatable results are required.

This reamer is applied in production and job-shop machining environments where close-tolerance hole sizing is needed after drilling. The straight shank accepts standard chuck toolholding, giving it broad machine compatibility without specialized adapters. With an overall length of 2.75 inches and a flute length of 0.875 inches, it is sized for shallow-to-moderate depth reaming passes in ferrous and non-ferrous materials. It is a solid choice for maintenance shops, precision component manufacturers, and toolmakers working to tight dimensional callouts.

Key Features

• Solid carbide construction for rigidity and wear resistance in demanding materials
• 0.1890 inch diameter (wire gauge size 12) with +0.0001 to +0.0003 inch tolerance
• Four straight flutes with right-hand cutting direction for smooth bore finishing
• Straight shank for compatibility with standard drill chucks and toolholders
• Uncoated finish suitable for use with cutting fluids across a range of workpiece materials
• Overall length of 2.75 inches and flute length of 0.875 inches for controlled reach

Compatibility

Designed as an OEM-style precision reamer from M.A. FORD. Series 272, intended for use in standard drill chucks and straight-shank toolholding systems on CNC and manual machine tools.

Installation Notes

Chucking reamers are installed and operated by machining professionals. Always ensure the workpiece and machine spindle are secured before beginning the reaming operation. Power down the machine and lock out all energy sources before changing or inspecting tooling. Use appropriate cutting fluid for the workpiece material to extend tool life and maintain bore surface finish quality.
