Insert for Stainless Steel

Kennametal has added a new Medium Roughing Geometry Insert for Stainless Steel in the BeyondTM range. The new Beyond MR (medium roughing) inserts a synergy of geometry and grade, with smooth cutting action and higher wear resistance among the results. Turning more parts per shift or extending tool life is a common “either-or” trade-off throughout the world’s shop floors. Suitable for a wide range of workpiece materials, but ideal for stainless steels, Kennametal’s new Beyond MR inserts are a product of ongoing design leadership, engineering, materials science, and manufacturing that delivers a perfect combination of smooth cutting action and stable edge performance. Faster cycle times and long tool life are the results. The uniqueness of Beyond MR is based in part on designing the geometry of the chip step in a continuous curve so that alternating stresses are reduced. From the lowest point of the chip step, the small radius of curvature grows larger, constituting the outlet region. As the surface of the chip step always has a curve, uniform chip forming occurs. Chips tend to deform continuously within the chip step, minimizing the friction of the chip on the tool face. Beyond MR is available in six grades, covering a complete range of applications for turning stainless. Grades are also available for steels and cast irons as well.
