The Niagara Cutter NS240R long flute finisher is a geometry for optimized performance in general machining. The NS240R allows one pass machining in square shoulder milling applications, thus reducing cycle time. These end mills are designed especially to produce high tolerance straight walls in deep pockets and to provide excellent surface quality. The Niagara Cutter long flute finishers are offered with a 5XD depth of cut as standard, ranging in diameters from 1/4 to 1-1/4 in with various radii available. The NS240R is effective in most materials but excels in stainless steel and titanium. A typical application for this end mill is in the manufacture of aerospace structural parts made from titanium and aluminum.
