Positive Geometry Inserts minimize downtime and scrap.

Press Release Summary:




Providing both 7° and 11° positive rake angles, along with precision-ground and precision-sintered cutting edges, Tiger•tec® Silver MP4, MM4, and MK4 Inserts boost performance in steel, stainless, and iron machining operations. Chip forming geometry features 12° rake angle for optimal shearing action when cutting stainless or low-carbon steel, while additional 18° chip groove in corner radius area optimizes chip control in light finishing cuts.

New Geometries from Walter Boost Machining Performance



New Tiger•tec® Silver MP4, MM4, and MK4 inserts reduce downtime and scrap in steel, stainless, and iron machining operations.



Waukesha, WI—Walter has introduced a trio of universal, positive insert geometries that reduce downtime and boost performance in steel, stainless and iron machining (ISO material types P, M, and K).



The new Tiger•tec® Silver MP4, MM4 and MK4 are light cutting and universal positive geometries in both 7° and 11° positive rake angles along with precision-ground and precision-sintered cutting edges. The chip forming geometry features a 12° rake angle for excellent shearing action when cutting stainless or low-carbon steel, along with an additional 18° chip groove in the corner radius area for excellent chip control in light finishing cuts. The D- and V- style inserts also have a curved main cutting edge for reduced cutting forces and clearance in profiling operations.



Typical applications for the new geometries include boring operations of all types, profile turning, turning or boring of thin wall or unstable workpieces; internal machining with long overhangs; and on Swiss type machines or multi-spindle machines. The new Tiger•tec Silver MP4, MM4, and MK4 geometries are available in grades WPP10S, WPP20S, WMP20S, WKK10S, WKK20S.



Field tests have shown that these new geometries provide longer tool life, better chip control, greater reliability and performance increases of up to 75% thanks to their Tiger•tec Silver coating.



Walter, a global leader in the metalworking industry with over 90 years of experience in precision cutting tools for milling, drilling, turning, boring and specialized tools, helps customers improve process reliability and increase productivity.
