Indexable Square-Shoulder Face Mill: RA390-051C6-43M, 2'' Cut Dia, 2.4803" Arbor Hole Dia, 1.7200" Max Cutting Depth MPN:5740062

An Indexable Square Shoulder Face Mill is an essential tool in milling applications requiring precision cuts to create square or flat surfaces with a shoulder in the cut edge while minimizing rounding errors introduced by the cutting action during milling operations like grooving, parting-off, profiling and slitting. This RA390 model offers a 2 cutting diameter for improved productivity as it can process larger volumes within one pass compared to smaller counterparts without compromising surface finish quality. With an arbor hole diameter of 2.4803 inches, users can mount and use the cutter in various milling machines securely while the maximum cutting depth capability of 1.7200 inches enables deep cutting applications with minimum interruptions or multiple passes to achieve the desired finished size as recommended by industry standards thus enhancing productivity and efficiency in machining activities.
