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

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

The notion, 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 with a specific hand tool, and are held securely in place without having the need for clamps, upper jaws or set screws that can weaken the insert and disrupt chip flow. The pocket design uses cutting forces to retain the insert seated firmly in position, removing any risk of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus increased pocket and insert life.

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

Launched in late '07, the new Sumo Tec treatment flattens the insert's coated surface to eradicate microscopic stress raisers, diminish heat and friction and improve chip flow. The result is improved toughness and opposition to chipping and built-up edge, all leading to longer tool lifespan. The golden-colored flank on Sumo Tec inserts facilitates wear detection. Size for size, Tangslit cutters give more teeth than Iscar's SGSF cutters, allowing higher feed rates.

Their superior rigidity leads to straighter, more accurate cuts and less vibration even in large-diameter cutters. The revolutionary Tangslit TGSF cutters come in 100 to 160 mm diameters, 3 and 4 mm widths and can accommodate the exact same variety of inserts as Tang-Grip parting tools. Additional sizes will be added.

Available Sumo Tec grades for Tangslit cutters include:
IC808, with a tough submicron substrate below a Sumo Tec TiAlN PVD coating, delivering outstanding 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, supplying additional toughness for heavier parting & grooving involving interrupted cuts. It is suitable for any stainless steel and high temperature alloys.

IC908, a hard, fine-grain substrate with outstanding chipping resistance, combined with a new Sumo Tec TiAlN PVD coating. It is perfect 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 also recommended for interrupted cuts and heavy operations.

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

Iscar Recently Made Public Several 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.

Various Developments Have Increased Iscar's Families Of Indexable Endmills For Increased 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.

New Cutters And Carbide Insert Configurations From Iscar To Better Maximize The Machining Procedure
Iscar is introducing Penta 34 carbide inserts with a new PB chipformer. The PB chipformer features a single cavity with a positive rake, neutral shoulder angle, and a honed edge. It is actually a C-type chipformer with a different frontal edge.

Cutting Edge End Mills Coming From Iscar Will Raise Productivity While Shrinking 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.
