M.a. Ford. 27213780 Chucking Reamer 3.5mm Solid Carbide

Product Description

The M.A. FORD. 27213780 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a 3.5 mm (0.1378 inch) reamer diameter and a diameter tolerance of +0.005/+0.010 mm, this tool delivers tight, repeatable bore sizing. The 4-flute straight flute geometry and right-hand cutting direction provide smooth, controlled material removal. At 2-1/2 inches overall length with a 3/4 inch flute length, this compact reamer is suited for short-reach finishing operations. It is installed and operated by machinists and tool-and-die professionals working on CNC machining centers, drill presses, and manual mills.

This chucking reamer is intended for precision reaming of small-diameter bores in the 3.00 to 4.00 mm range. The straight shank design allows direct mounting in standard drill chucks, collet chucks, and floating reamer holders. Its uncoated solid carbide construction makes it a strong choice for reaming ferrous and non-ferrous materials where dimensional accuracy is critical. The tool does not support coolant-through delivery and is not configured as a dowel pin reamer or an over/under size reamer, making it a standard production reamer for general precision finishing work.

Key Features

• 3.5 mm (0.1378 inch) reamer diameter with +0.005/+0.010 mm tolerance for precise bore sizing
• Solid carbide construction for rigidity and wear resistance in demanding machining environments
• 4-flute straight flute design promotes smooth cutting action and consistent finish
• Right-hand spiral direction and right-hand cutting orientation for standard spindle compatibility
• Straight shank fits standard chucks and collet holders without adapters
• Uncoated finish suitable for a broad range of ferrous and non-ferrous workpiece materials

Compatibility

Designed as an OEM-style replacement or production chucking reamer for applications requiring a 3.5 mm bore finish in the M.A. FORD. Series 272 product line.

Installation Notes

This reamer should be installed by qualified machinists familiar with precision hole-finishing operations. Power down and lock out the spindle before mounting or removing the tool from the chuck or collet holder. Use a floating reamer holder where possible to compensate for minor misalignment and prevent tool breakage. Do not use this reamer to remove excessive stock; pre-drill or bore the hole to within the recommended allowance before reaming.
