Iscar Announces A New Family Of Slitting Cutters Utilizing Tang-Grip Technology And The Sturdiness Of Sumo Tec Grades

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

The idea, already verified 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 accompanied by a specific hand tool, and are gripped securely in place without the need for clamps, upper jaws or set screws that can weaken the insert and block chip flow. The pocket composition uses cutting forces to keep the insert seated firmly in position, removing any chance of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus lengthened pocket and insert life.

Iscar's Sumo Tec insert grades feature a unique post-coating treatment which substantially improves tool life and dependability.

Launched in late '07, the new Sumo Tec treatment flattens the insert's coated surface to eradicate microscopic stress raisers, decrease heat and friction and increase chip flow. The result is improved toughness and resistance to chipping and built-up edge, all leading to greater 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 higher rigidity leads to straighter, additional accurate cuts and diminished vibration even in 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 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 superb resistance to impact loads and built-up edge. This grade is suggested for slitting heat resistant alloys, austenitic stainless steel, hard alloys and carbon steel.

IC830, offering additional toughness for heavier parting & grooving involving interrupted cuts. It is suitable for every stainless steel and high temperature alloys.

IC908, a hard, fine-grain substrate with exceptional chipping resistance, mixed with a new Sumo Tec TiAlN PVD coating. It is ideal 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.

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

Brand New Tools 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.

Iscar Adds Their Latest Creations To A Long Line Of Successful Hole Producing 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.

A Couple Of The Many Improvements In Carbide Inserts 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 Number Of Developments Have Broadened Iscar's Line Of Indexable Endmills For Heightened 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.

Brand New End Mills Coming From Iscar Will Boost 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.
