M.a. Ford. 27204300 Chucking Reamer Wire Size 57 Solid Carbide

Product Description

The M.A. FORD. 27204300 is a solid carbide chucking reamer designed to finish-ream drilled holes to a precise wire gauge No. 57 diameter of 0.0430 inches. With a diameter tolerance of +0.0001 to +0.0003 inches, this tool holds tight dimensional accuracy critical for precision machining applications. The straight flute geometry and right-hand cut make it well-suited for through-hole and blind-hole reaming in a variety of workpiece materials. At 1.5 inches overall length with a 3/8-inch flute length and a straight shank, it mounts directly in standard chucks or collets on CNC machining centers, drill presses, and manual mills. Licensed machinists and toolroom technicians are the typical users.

This reamer is intended for small-diameter precision hole finishing in metalworking environments, including tool-and-die shops, production machining floors, and maintenance repair operations. The wire size 57 designation places it in the sub-0.05-inch diameter range, where solid carbide construction provides the rigidity needed to hold size and finish without deflection. It is part of M.A. FORD. Series 272 and carries a package quantity of one unit per order.

Key Features

• Solid carbide construction provides rigidity and wear resistance in small-diameter reaming
• Wire size No. 57 diameter of 0.0430 inches with a tight tolerance of +0.0001 to +0.0003 inches
• Straight flute, right-hand cut geometry for consistent chip evacuation
• Straight shank for direct mounting in standard chucks and collets
• Four flutes for improved surface finish and dimensional consistency
• Uncoated carbide substrate suitable for use with appropriate cutting fluids

Compatibility

Designed as an OEM-style precision reamer for use in standard chuck or collet toolholding systems accepting a straight shank in the sub-0.05-inch diameter range.

Installation Notes

Install in a rigid collet or drill chuck with minimal runout before use, as runout at this diameter range directly affects hole size and finish. Power down and lock out the spindle before changing tooling. Apply a suitable cutting fluid for the workpiece material to extend tool life and improve surface finish. Handle solid carbide tooling with care to avoid chipping the cutting edges during storage and setup.
