M.a. Ford. 27202400 Chucking Reamer Wire Size 73 Solid Carbide

Product Description

The M.A. FORD. 27202400 is a solid carbide chucking reamer designed for precision hole finishing in tight-tolerance machining applications. Built to wire gauge size 73, it produces a finished bore diameter of 0.0240 inches with a reamer diameter tolerance of +0.0001 to +0.0003 inches. The four-flute, straight-flute geometry delivers consistent chip evacuation and a clean surface finish on through-holes and blind holes alike. With a 1-1/2 inch overall length and a 1/4 inch flute length, this reamer is suited for shallow finishing passes on small-diameter bores. It is installed and operated by machinists and tool-and-die professionals working on CNC machining centers, drill presses, or manual mills.

This reamer is intended for small-diameter precision finishing work in production and job-shop environments. The 0.0240 inch cutting diameter places it squarely in the sub-1/16 inch range, making it appropriate for instrument-grade components, medical parts, watch-making fixtures, small hydraulic passages, and similar precision-machined features. The straight shank fits standard chucks and collets without adapters. Right-hand cutting direction is standard for conventional machine spindle rotation. No coolant-through capability is required for the light chip loads typical at this diameter.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small cutting diameters
• Wire size 73 cutting diameter of 0.0240 inches with tolerance of +0.0001 to +0.0003 inches
• Four straight flutes for smooth chip flow and consistent finish in short-flute applications
• Uncoated ground carbide cutting edges ready for immediate use on ferrous and non-ferrous materials
• Straight shank for direct chuck or collet mounting without additional toolholding adapters
• Right-hand cut and right-hand spiral direction compatible with standard CNC and manual spindle rotation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems accepting straight-shank tooling at sub-1/16 inch diameters. No specific compatible machine models were identified in the product data.

Installation Notes

Chucking reamers should be installed by qualified machinists familiar with small-diameter tooling practices. Power down and lock out the machine spindle before seating or removing the tool from the chuck or collet. Ensure the shank is fully seated and the chuck is tightened to the manufacturer specification for the toolholder in use. At this diameter, excessive feed rate or misalignment is the primary cause of tool breakage, so verify workpiece alignment and use appropriate low-feed, high-speed parameters before initiating the cut.
