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

Iscar currently offers a family of high-performance slitting tools that join the convenience and security of Tang-Grip clamping with the increased strength of the 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 accompanied by a specialized hand tool, and are clutched solidly in place without the need for 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 tightly in position, eliminating any prospect of insert pull-out. The Tang-Grip clamping system also fosters additional accurate slitting cuts plus lengthened pocket and insert life.

Iscar's Sumo Tec insert grades feature a special post-coating treatment which considerably boosts tool life and dependability.

Introduced in late 2007, the unique Sumo Tec treatment flattens the insert's coated surface to eliminate 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 greater tool life. The golden-colored side on Sumo Tec inserts eases wear detection. Size for size, Tangslit cutters give more teeth than Iscar's SGSF cutters, enabling higher feed rates.

Their greater rigidity leads to straighter, more accurate cuts and lowered 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. Several 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, offering 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, giving increased toughness for heavier parting and grooving including interrupted cuts. It is appropriate for every stainless steel and high temperature alloys.

IC908, a hard, fine-grain substrate with excellent chipping resistance, combined 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 additionally favored for interrupted cuts and heavy operations.

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

Iscar Recently Releases Numerous Brand New Lines To Increase 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.

The Most Recent In Carbide Endmill Architectures In A Extended And Productive Line From Iscar
Manufacturers and die & mold shops can eliminate chatter problems in many milling operations with Iscar's new Chatterfree endmills. The cutters' variable-pitch flute pattern eliminates harmonic vibration, the main source of chatter. This enables faster cutting and finer finish in rough or finish slotting, shoulder milling and cavity milling.

Cutting Edge Tools And Carbide Insert Arrangements From Iscar To Better Enhance 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.

Several Improvements Have Enhanced 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.

A Few Of Advancements In Carbide Inserts From Iscar Across The Past Decade
Iscar is announcing a brand new unique milling system that includes tangential, clamped, butterfly-shaped LNKX carbide inserts. The butterfly-shaped insert has meaningful advantages compared to the current flat, square shapes. The new geometry has more cutting edges, positive rake face, decreased cutting forces resulting in better performance.
