M.a. Ford 27204650 Chucking Reamer No. 56 Solid Carbide

Product Description

The M.A. FORD 27204650 is a solid carbide chucking reamer sized to No. 56 wire gauge, with a decimal diameter of 0.0465 inches. It is designed to finish-ream precision holes to tight tolerances in metal workpieces, producing a clean, accurate bore ready for fasteners, dowel pins, or close-tolerance fits. The reamer features a straight flute geometry and a right-hand cutting direction, with a tolerance of +0.0001 to +0.0003 inches over nominal diameter. It belongs to M.A. FORD Series 272 and is intended for use in CNC machining centers, drill presses, or manual chucking setups by machinists and toolroom professionals.

This reamer is suited for light-stock removal finish reaming operations in ferrous and non-ferrous metals where hole accuracy and surface finish are critical. The small diameter makes it appropriate for precision instrument work, electronics hardware, and fine mechanical assemblies. With a 1.5 inch overall length and a 0.375 inch flute length, it fits standard collet chucks and drill chucks in both production and job-shop environments. No coolant-through capability is required for the applications this size class typically serves.

Key Features

• Solid carbide construction provides rigidity and wear resistance at small diameters
• No. 56 wire size, 0.0465 inch decimal diameter with +0.0001 to +0.0003 inch tolerance
• Straight flute, right-hand cut geometry for stable, chatter-reduced reaming
• 4-flute design balances cutting load and chip evacuation in small bores
• Straight shank seats securely in standard collet chucks and drill chucks
• Uncoated carbide substrate suitable for a wide range of metallic workpiece materials

Compatibility

Designed as an OEM-style precision reamer for use in any chucking setup accepting a straight-shank tool of this diameter class. Compatible with standard collet systems and drill chucks sized for small-diameter straight shanks.

Installation Notes

Chucking reamers of this diameter class are installed and operated by machinists following standard shop practices. Ensure the workpiece is securely fixtured and the reamer is running true in the chuck before engaging the bore. Use appropriate cutting fluid for the workpiece material to extend tool life and improve surface finish. Handle solid carbide tooling carefully to avoid chipping the cutting edges during setup and storage.
