M.a. Ford 27219650A Chucking Reamer 0.1965 in Carbide 4 Flute

Product Description

The M.A. FORD 27219650A is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built to Series 272 standards, it features a 0.1965-inch reamer diameter with a tight tolerance of +0.0001 to +0.0003 inches, making it suitable for close-tolerance bores where dimensional accuracy is critical. The reamer has a 3-inch overall length and a 1-inch straight flute, with a right-hand cutting direction. The ALtima coating provides added wear resistance for extended tool life in demanding cutting conditions. This tool is installed and operated by machinists, toolroom technicians, and precision metalworking professionals.

The 27219650A is applied in production and toolroom environments where hole finishing to precise diameter tolerances is required. The straight-cylindrical shank mounts directly into standard drill chucks, collets, or machine tool holders on lathes, drill presses, and machining centers. Its 0.1965-inch diameter places it in the 0.1500 to 0.1999-inch range, suited for finishing small-diameter bores in ferrous and non-ferrous materials. The 4-flute straight configuration supports consistent chip evacuation and surface finish in through and blind hole applications.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• ALtima coating for improved tool life in demanding cutting environments
• Reamer diameter tolerance of +0.0001 to +0.0003 inches for close-tolerance bore finishing
• 4-flute straight configuration with right-hand cutting direction
• Straight-cylindrical shank for compatibility with standard chucks and collets
• Series 272 modified standard designation

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, collets, and machine tool holders accepting a straight-cylindrical shank in the 0.1965-inch diameter range.

Installation Notes

Installation is performed by machinists or toolroom technicians. The reamer should be secured in a clean, properly sized chuck or collet and run at speeds and feeds appropriate for solid carbide tooling in the workpiece material. Ensure the machine spindle and tool holder are free of chips and debris before seating the shank. Note that this item is designated as non-returnable and non-cancelable per manufacturer classification.
