Iscar Offers A Brand New Line Of Slitting Cutters Utilizing Tang-Grip Technology And The Durability Of Sumo Tec Grades

Iscar currently offers a family of high-performance slitting tools that combine the convenience and security of Tang-Grip clamping with the increased sturdiness of the new Sumo Tec insert grades.

The notion, already demonstrated effective in Tang-Grip parting tools, has now been extended to slitting cutters. In the patented Tang-Grip clamping system, inserts are press-fit into their pockets accompanying a specific hand tool, and are retained securely in place without the need for clamps, upper jaws or set screws that can weaken the insert and obstruct chip flow. The pocket design utilizes cutting forces to retain the insert seated solidly in position, eliminating any prospect of insert pull-out. The Tang-Grip clamping system also fosters additional accurate slitting cuts plus increased pocket and insert lifespan.

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

Unveiled in late 2007, the brand new Sumo Tec treatment flattens the insert's coated surface to eradicate microscopic stress raisers, reduce heat and friction and improve chip flow. The result is improved toughness and resistance 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 give more teeth than Iscar's SGSF cutters, permitting higher feed rates.

Their higher rigidity leads to straighter, more accurate cuts and diminished vibration even in large-diameter cutters. The brand new Tangslit TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accommodate the exact same assortment of inserts as Tang-Grip parting tools. Some other sizes will be added.

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

IC830, giving increased toughness for heavier parting and grooving involving interrupted cuts. It is fitting for all stainless steel and high temperature alloys.

IC908, a hard, fine-grain substrate with extraordinary chipping resistance, mixed with a brand new Sumo Tec TiAlN PVD coating. It is perfect for nodular or grey cast iron.

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

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