M.a. Ford 27210400 Chucking Reamer 37 Solid Carbide

Product Description

The M.A. FORD 27210400 is a solid carbide chucking reamer designed for precision hole finishing in metalworking applications. Built to wire size 37, it produces a finished bore diameter of 0.1040 inches with a tight tolerance of +0.0001 to +0.0003 inches, making it suitable for close-tolerance fits and dowel or pin-clearance work. The four-flute, straight-flute geometry provides consistent chip evacuation and a smooth finish in short-to-medium depth holes. With an overall length of 2.25 inches and a flute length of 0.625 inches, this reamer is sized for compact chucking setups on drill presses, CNC machining centers, and manual lathes.

This reamer is used in general precision machining environments where small-diameter bores require tight dimensional control. The straight shank mounts directly into standard drill chucks, collet holders, or floating reamer holders. Right-hand cutting direction and uncoated solid carbide construction make it well suited for reaming ferrous and non-ferrous materials where dimensional accuracy is the priority. Machinists, tool and die makers, and CNC operators working in job shop or production environments will find this reamer appropriate for finishing pre-drilled holes to wire size 37 specification.

Key Features

• Wire size 37 diameter: 0.1040 inches with tolerance of +0.0001 to +0.0003 inches
• Solid carbide construction for rigidity and wear resistance in precision applications
• Four straight flutes with right-hand cutting direction for consistent finish
• Straight shank compatible with standard drill chucks and collet holders
• Compact 2.25-inch overall length suited for close-quarters chucking setups
• Uncoated finish — no coating interaction with workpiece material to account for

Compatibility

Designed as an OEM-style precision chucking reamer for use in standard straight-shank toolholders, drill chucks, and collet systems capable of accepting a straight shank at the 0.1040-inch diameter range.

Installation Notes

Installation and use should be performed by a qualified machinist familiar with reaming operations and cutting tool safety. Ensure the spindle is fully stopped and machine power is off before mounting or removing the reamer from the holder. Use a floating reamer holder where possible to compensate for minor misalignment and prevent tool deflection. Always pre-drill the hole to the correct undersize before reaming, and apply appropriate cutting fluid for the workpiece material to extend tool life and maintain bore finish quality.
