1 1/9 A New Positive ulti Corners illing Line

2 2/9 With the increasing popularity of small machining centers, TaeguTec is pleased to launch a new single-sided line of positive seven corners insert that generates less cutting force. The CHASEHEPTA insert generates low cutting force, achieves smooth machining and greater economy due to its seven corner and helical cutting edges. Additionally, the CHASEHEPTA's higher insert thickness means better resistance to shock and breakage, hence, overcoming the primary weakness of single-sided positive inserts. The new line, designated as 7ET 0604, is available in two geometries; the "" type for steel and cast iron and the "L" type for stainless steel and difficult-to-cut materials. The line's cutters have a 45 degree entering angle, a 3.2 mm maximum depth of cut and are available in endmills (D32-50mm) as well as face mill types (D32-125mm) covering not only general face milling but ramping and profiling proving its advantage as a multipurpose tool. FEATURES Insert Economical 7-corner cutting edges Higher insert thickness means better rigidity Smooth machining with helical cutting edge 5 Optimized chip formers for various workpieces: L For steel and cast iron For stainless steel and difficult-to-cut materials
