M.a. Ford. 27212200 Chucking Reamer 3.10mm Solid Carbide

Product Description

The M.A. FORD. 27212200 is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 3.10mm (0.1220 inches), an overall length of 57.00mm (2.25 inches), and a 16.00mm (0.63 inches) straight flute length, this tool delivers controlled material removal for tight-tolerance bores. The bright, uncoated solid carbide construction provides rigidity and wear resistance suitable for close-tolerance reaming operations. Four straight flutes in a right-hand cutting direction ensure smooth chip evacuation and consistent surface finish. It fits standard chucks and collets via its straight-cylindrical shank, making it a straightforward drop-in for CNC machining centers and manual mills alike.

This reamer is suited for production and job-shop environments where precise hole sizing in the 3.00mm to 4.00mm diameter range is required. Typical applications include finish-reaming drilled or bored holes in ferrous and non-ferrous materials where dimensional accuracy is critical. The Series 272 designation places it within M.A. FORD.'s line of standard solid carbide chucking reamers. Machinists and toolroom technicians working with close-tolerance assemblies, dowel holes, and precision fits will find this tool appropriate for both low-volume prototype work and higher-volume production runs.

Key Features

• Solid carbide construction for rigidity and extended tool life in hard or abrasive materials
• 3.10mm (0.1220 inches) diameter with a tolerance of +0.005 to +0.010mm for controlled oversize finishing
• Four straight flutes in right-hand cutting direction for smooth, consistent chip flow
• Bright, uncoated finish suitable for use with standard cutting fluids or dry applications
• Straight-cylindrical shank for compatibility with standard chucks and collet systems
• No coolant-through feature, simplifying setup in conventional machining environments

Compatibility

Designed as an OEM-style solid carbide chucking reamer for use in standard chuck or collet toolholders accommodating a straight-cylindrical shank in the 3.00mm to 4.00mm diameter range.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight-cylindrical shank firmly in a compatible chuck or collet holder before operation, and verify runout with a dial indicator to maintain tolerance. Power down and de-energize the machine spindle completely before installing or removing the reamer. Do not force the reamer into an undersized pilot hole; ensure the pre-drilled or bored hole is within the recommended allowance for the reamer diameter prior to use.
