Iscar Announces A Brand New Family Of Slitting Cutters Applying Tang-Grip Technology And The Durability Of Sumo Tec Grades
Iscar now offers a family of high-performance slitting tools that merge the convenience and security of Tang-Grip clamping with the increased durability of the completely new Sumo Tec insert grades.
The concept, already proven 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 accompanying a special hand tool, and are clutched tightly in place without the need without requiring clamps, upper jaws or set screws that can weaken the insert and impede chip flow. The pocket design uses cutting forces to hold the insert seated solidly in position, eliminating any prospect of insert pull-out. The Tang-Grip clamping system also fosters increased accurate slitting cuts plus longer pocket and insert lifespan.
Iscar's Sumo Tec insert grades feature a special post-coating treatment which considerably boosts tool life and constancy.
Introduced in late 2007, the completely new Sumo Tec treatment smooths the insert's coated surface to dispose of microscopic stress raisers, reduce heat and friction and improve chip flow. The result is improved toughness and opposition to chipping and built-up edge, all leading to enhanced tool life. The golden-colored side on Sumo Tec inserts aides wear detection. Size for size, Tangslit cutters offer more teeth than Iscar's SGSF cutters, permitting higher feed rates.
Their greater 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 accept the exact same selection of inserts as Tang-Grip parting tools. Some other sizes will be added.
Existing Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate beneath a Sumo Tec TiAlN PVD coating, providing excellent 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, presenting greater toughness for heavier parting and grooving including interrupted cuts. It is suited for all stainless steel & high temperature alloys.
IC908, a hard, fine-grain substrate with excellent chipping resistance, combined with a 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 suggested for interrupted cuts and heavy operations.
All Tangslit and Tang-Grip inserts are attainable in J- or C-type chipformer geometries from Iscar.
Iscar Recently Releases Many Revolutionary Lines To Continue Their Family Of Milling Cutters Iscar recently released a new family of High Speed Milling adjustable endmills and facemills that will improve milling of aluminum, non-metallics, cast iron and hardened steel. This should prove especially useful in the automotive and aerospace industries.

A Couple Of Advancements In Carbide Inserts Coming From Iscar Over The Last Decade Iscar is introducing a new unique milling system with tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has significant advantages compared to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, reduced cutting forces resulting in higher performance.
A Variety Of Progressions Have Multiplied Iscar's Line Of Indexable Endmills For Expanded Productivity Helido-Upfeed 04 Two years ago Iscar introduced the extremely efficient H600 indexable endmill line, based on conceptually new Helido-Upfeed double sided inserts with 6 cutting edges. The first insert launched was the H600 WXCU 0806..., which was designed for milling cutters in the diameter range of 50 to 125 mm.
Completely New End Mills Coming From Iscar Can Increase Productivity While Cutting Down Costs Manufacturers and die & mold shops can banish chatter problems in numerous milling operations with Iscar's new Chatterfree end mills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the primary source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.
