M.a. Ford. 27224980 Chucking Reamer 1/4 Inch Solid Carbide

Product Description

The M.A. FORD. 27224980 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 0.2498 inch cutting diameter and a tight tolerance of +0.0001 to +0.0003 inches, this reamer holds close dimensional control for fitted holes and dowel pin bores. The four-flute straight configuration and right-hand cutting direction deliver smooth, consistent stock removal. At 3 inches overall length with a 1 inch flute length, the compact profile suits short-reach setups in drill presses, CNC machining centers, and manual milling machines. Licensed machinists and tool-and-die tradespeople are the primary installers.

This reamer fits common production and maintenance machining scenarios where a 1/4 inch nominal bore requires a finished, close-tolerance diameter. The straight-cylindrical shank allows direct chucking in standard keyless or keyed drill chucks and collet holders without additional adapters. The bright, uncoated carbide surface is appropriate for use in non-ferrous metals, cast iron, and other materials where coating buildup is a concern. It is sold individually and ships as a single unit per package.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• 0.2498 inch actual cutting diameter with +0.0001 to +0.0003 inch tolerance for close-fit applications
• Four straight flutes with right-hand cut for smooth, chatter-free stock removal
• Bright uncoated finish suited for non-ferrous and ferrous materials where coating is not required
• Straight-cylindrical shank for direct chucking in standard drill chucks and collet holders
• Compact 3 inch overall length with 1 inch flute length for short-reach setups

Compatibility

Designed as an OEM-style replacement or direct-use chucking reamer for standard 1/4 inch bore finishing operations across drill presses, CNC machining centers, and manual mills using standard straight-shank toolholders.

Installation Notes

Installation is performed by qualified machinists following standard toolroom practices. Power down and lock out the machine spindle before inserting or removing the reamer from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the toolholder specification before running the spindle. Use appropriate cutting fluid or coolant for the workpiece material to extend tool life, noting this reamer does not support through-tool coolant delivery.
