ISCAR now offers a family of high-performance slitting tools that combine the convenience and security of TANG-GRIP clamping with the added durability of the new SUMO TEC insert grades. The concept, already proven successful 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 with a special hand tool, and are held securely in place without clamps, upper jaws or set screws that can weaken the insert and impede chip flow. The pocket design uses cutting forces to keep the insert seated securely in position, eliminating any risk of insert pull-out. The TANG-GRIP clamping system also fosters more accurate slitting cuts plus longer pocket and insert life.
ISCAR’s SUMO TEC insert grades feature a special post-coating treatment which substantially improves tool life and reliability. Introduced in late ’07, the new SUMO TEC treatment smoothes the insert’s coated surface to eliminate 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 longer tool life. The golden-colored flank on SUMO TEC inserts facilitates wear detection.
Size for size, TANGSLIT cutters offer more teeth than ISCAR’s SGSF cutters, enabling higher feed rates. Their greater rigidity leads to straighter, more accurate cuts and less vibration in even large-diameter cutters.
The new TANGSLIT TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accommodate the exact same selection of inserts as TANG-GRIP parting tools. Additional sizes will be added.

Available SUMO TEC grades for TANGSLIT cutters include:
