Iscar Announces A New Family Of Slitting Cutters Applying Tang-Grip Technology And The Sturdiness Of Sumo Tec Grades



Iscar now offers a family of high-performance slitting tools that incorporate the convenience and security of Tang-Grip clamping with the added durability of the revolutionary Sumo Tec insert grades.

The conception, already confirmed successful in Tang-Grip parting tools, has now been spread to slitting cutters. In the patented Tang-Grip clamping system, inserts are press-fit into their pockets accompanied by a distinct hand tool, and are gripped tightly in place without having the need without requiring clamps, upper jaws or set screws that can weaken the insert and block chip flow. The pocket configuration utilizes cutting forces to retain the insert seated securely in position, removing any prospect of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus lengthened pocket and insert life.

Iscar's Sumo Tec insert grades showcase a specialized post-coating treatment which substantially boosts tool life and constancy.

Launched in late '07, the completely new Sumo Tec treatment smooths the insert's coated surface to eliminate microscopic stress raisers, reduce heat and friction and enhance chip flow. The result is enhanced toughness and opposition to chipping and built-up edge, all leading to greater tool lifespan. The golden-colored flank on Sumo Tec inserts eases wear detection. Size for size, Tangslit cutters offer more teeth than Iscar's SGSF cutters, enabling higher feed rates.

Their increased rigidity leads to straighter, additional accurate cuts and reduced vibration even in large-diameter cutters. The new Tangslit TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accept the exact same variety of inserts as Tang-Grip parting tools. Several other sizes will be added.

Obtainable Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate beneath a Sumo Tec TiAlN PVD coating, giving incredible resistance to impact loads and built-up edge. This grade is endorsed for slitting heat resistant alloys, austenitic stainless steel, hard alloys & carbon steel.

IC830, providing greater toughness for heavier parting and grooving involving interrupted cuts. It is appropriate for every stainless steel & high temperature alloys.

IC908, a hard, fine-grain substrate with extraordinary chipping resistance, combined with a completely new Sumo Tec TiAlN PVD coating. It is ideal for nodular or gray cast iron.

IC928 and 928A, PVD TiAlN-coated tough grades fitting for stainless steel, high temperature alloys and other alloy steels. These grades are additionally favored for interrupted cuts and heavy operations.

Each Tangslit and Tang-Grip inserts are available in J- or C-type chipformer geometries from Iscar.
