M.a. Ford 27212800T Chucking Reamer 3.25mm Solid Carbide Tin

Product Description

The M.A. FORD 27212800T is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. Built to Series 272 standards, it features a 3.25 mm (0.1280 inch) diameter with a diameter tolerance of +0.005 to +0.010 mm, making it suitable for tight-tolerance bore work. The reamer has a straight-cylindrical shank for secure chuck mounting and four straight flutes with right-hand cutting direction. Overall length is 57.00 mm (2.25 inches) with a 16.00 mm (0.63 inch) flute length. A titanium nitride (TiN) coating provides surface hardness and wear resistance. Machinists and tool-and-die professionals use this reamer for finishing pre-drilled or bored holes to close dimensional tolerances.

This reamer is suited for production and jobshop machining environments where consistent hole geometry and surface finish are required. The 3.25 mm diameter falls within the 3.00 to 4.00 mm reamer diameter range, making it appropriate for small-bore finishing on ferrous and non-ferrous workpiece materials. It is classified as a modified standard item and is designated non-returnable and non-cancelable by the manufacturer. The solid carbide construction and TiN coating support use in harder materials and higher-speed operations compared to high-speed steel equivalents.

Key Features

• Solid carbide construction for rigidity and long tool life in demanding materials
• TiN coating for improved wear resistance and reduced friction at the cutting edge
• 3.25 mm diameter with +0.005 to +0.010 mm tolerance for precision bore finishing
• Four straight flutes with right-hand cutting direction for smooth, consistent material removal
• Straight-cylindrical shank for direct chuck or collet mounting without special adapters
• Compact 57.00 mm overall length suited for short-reach and high-speed spindle setups

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard drill chucks, collet chucks, or floating holders accepting a straight-cylindrical shank in the 3.00 to 4.00 mm diameter class.

Installation Notes

Installation and use should be performed by qualified machinists familiar with reaming operations. Ensure the spindle and workpiece fixture are fully stopped and locked out before mounting or removing the reamer. Use a properly sized collet or chuck to achieve full shank engagement and minimize runout. This item is designated non-returnable and non-cancelable by the manufacturer; verify diameter and tolerance requirements before ordering.
