M.a. Ford. 27212550C Chucking Reamer 0.1255 in Solid Carbide

Product Description

The M.A. FORD. 27212550C is a solid carbide chucking reamer designed for precision hole finishing in metalworking and machining applications. With a reamer diameter of 0.1255 inches and a diameter tolerance of +0.0001 to +0.0003 inches, this tool delivers tight, consistent bore sizing in a single pass. The straight flute geometry and right-hand cut direction make it well suited for through-holes and shorter chipping materials. At 2.25 inches overall length with a 0.625 inch flute length and a straight shank, it mounts directly in a drill chuck or collet on standard machine setups. The TiCN coating improves surface hardness and wear resistance for extended tool life in ferrous and non-ferrous materials.

This reamer is used in machine shop and production environments where finish-bore accuracy is critical. Typical applications include reaming drilled pilot holes to final tolerance in steel, cast iron, aluminum, and similar materials. It is installed in CNC machining centers, manual lathes, drill presses, and knee mills. The straight shank allows it to run in a standard drill chuck or ER collet system without additional adapters. This tool is classified as a modified standard item and is designated non-returnable and non-cancelable at time of order.

Key Features

• Solid carbide construction for rigidity and wear resistance in precision reaming
• TiCN coating for increased surface hardness and extended tool life
• Diameter tolerance of +0.0001 to +0.0003 inches for tight bore control
• Straight flute design suited for through-holes and short-chipping materials
• 4-flute geometry balances finish quality with chip evacuation
• Right-hand cut, straight shank for direct chuck or collet mounting

Compatibility

Designed as an OEM-style chucking reamer for use in standard drill chucks and collet systems on CNC machining centers, manual lathes, drill presses, and knee mills requiring a 0.1255 inch finished bore diameter.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Secure the straight shank in a properly sized collet or drill chuck and verify runout before cutting. Power down the machine and confirm the spindle is fully stopped before inserting or removing the tool. Use appropriate cutting fluid for the workpiece material to maintain dimensional accuracy and extend tool life. Note that this item is non-returnable and non-cancelable once ordered.
