Iscar Announces A Revolutionary Line Of Slitting Cutters Using Tang-Grip Technology And The Durability Of Sumo Tec Grades


Iscar at this time offers a family of high-performance slitting tools that incorporate the convenience and security of Tang-Grip clamping with the added strength of the completely new Sumo Tec insert grades.

The conception, already established 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 distinct hand tool, and are gripped firmly in place without the need without requiring clamps, upper jaws or set screws that can weaken the insert and hinder chip flow. The pocket configuration uses cutting forces to hold the insert seated securely in position, preventing any chance of insert pull-out. The Tang-Grip clamping system also fosters increased accurate slitting cuts plus lengthened pocket and insert lifespan.

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

Unveiled in late '07, the completely new Sumo Tec treatment flattens the insert's coated surface to dispose of microscopic stress raisers, decrease heat and friction and increase 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 aides wear detection. Size for size, Tangslit cutters give more teeth than Iscar's SGSF cutters, permitting higher feed rates.

Their improved rigidity leads to straighter, additional 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. Additional sizes will be added.

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

IC830, presenting extra toughness for heavier parting & grooving involving interrupted cuts. It is fitting for every stainless steel & high temperature alloys.

IC908, a hard, fine-grain substrate with exceptional chipping resistance, joined 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 suited for stainless steel, high temperature alloys and other alloy steels. These grades are also suggested for interrupted cuts and heavy operations.

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

Iscar Adds Their Latest Innovations To A Extensive Line Of Outstanding Hole Making Solutions
Iscar recently released several different drilling innovations to meet their customers needs. These new products are Sumocham Drill, DR-DH and Deep Drills. Drawing off of their experience Iscar has come up with new and innovative ways to increase productivity for the end user.

Numerous Advancements 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.

New End Mills Coming From Iscar Will Enhance Productivity While Lowering 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.

Brand New Tools And Carbide Insert Configurations From Iscar To Better Maximize The Machining Process
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.
