M.a. Ford. 27211810 Chucking Reamer 3mm Solid Carbide

Product Description

The M.A. FORD. 27211810 is a solid carbide chucking reamer designed to finish-ream precision holes to a 3 mm diameter. Solid carbide construction delivers the rigidity and wear resistance needed for tight-tolerance work in hardened or abrasive materials. The straight flute geometry suits reaming in through-holes where chip evacuation is straightforward. With a 2-1/4 inch overall length and a 5/8 inch flute length, this is a compact tool suited for short-reach applications. The diameter tolerance of +0.004/+0.008 mm supports consistent hole sizing across production runs. This reamer is installed and operated by machinists and tool room professionals working on CNC mills, drill presses, or manual lathes.

This chucking reamer is used in metalworking applications where holes must be sized and finished to close dimensional tolerances. The straight shank allows direct mounting in standard drill chucks, collet chucks, or floating reamer holders. Typical applications include finish-reaming dowel pin holes, bearing bores, and precision fit holes in ferrous and non-ferrous materials. The right-hand cutting direction is standard for conventional spindle rotation. No coolant-through capability is present, so external coolant or cutting fluid application is recommended when reaming steel or other tough alloys.

Key Features

• Solid carbide construction for rigidity and extended tool life in abrasive or hardened materials
• 3 mm reamer diameter with a tolerance of +0.004/+0.008 mm for precise hole sizing
• 4-flute straight design for clean finish on through-hole applications
• Straight shank compatible with standard drill chucks and collet holders
• Right-hand cut, right-hand spiral for use with conventional spindle rotation
• Uncoated carbide substrate suitable for a wide range of workpiece materials

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks, ER collet systems, and floating reamer holders accepting straight-shank tools at 3 mm diameter.

Installation Notes

Installation and operation should be performed by qualified machinists familiar with reaming procedures. Power down and lock out the machine spindle before mounting or removing the reamer from the holder. Ensure the shank is fully seated and the chuck or collet is tightened to the holder manufacturer's specified torque range before operation. Apply appropriate cutting fluid externally during the reaming operation to control heat and extend tool life, as this tool does not have coolant-through capability.
