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

The perception, already established effective 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 specific hand tool, and are retained securely in place without the need without requiring clamps, upper jaws or set screws that can weaken the insert and thwart chip flow. The pocket configuration utilizes cutting forces to hold the insert seated tightly in position, removing any danger of insert pull-out. The Tang-Grip clamping system also fosters more accurate slitting cuts plus longer pocket and insert lifespan.

Iscar's Sumo Tec insert grades showcase a unique post-coating treatment which greatly boosts tool life and constancy.

Launched in late 2007, the new Sumo Tec treatment smooths the insert's coated surface to dispose of microscopic stress raisers, lessen heat and friction and increase chip flow. The result is enhanced toughness and opposition to chipping and built-up edge, all leading to enhanced tool lifespan. The golden-colored side on Sumo Tec inserts facilitates wear detection. Size for size, Tangslit cutters offer more teeth than Iscar's SGSF cutters, permitting higher feed rates.

Their better rigidity leads to straighter, additional accurate cuts and lower 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 variety of inserts as Tang-Grip parting tools. Some other sizes will be added.

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

IC830, giving increased toughness for heavier parting & grooving including interrupted cuts. It is suitable for all stainless steel & high temperature alloys.

IC908, a hard, fine-grain substrate with incredible chipping resistance, joined with a completely new Sumo Tec TiAlN PVD coating. It is perfect for nodular or grey cast iron.

IC928 and 928A, PVD TiAlN-coated tough grades fitting for stainless steel, high temperature alloys and other alloy steels. These grades are likewise recommended 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 Numerous New Lines To Continue Their Family Of Milling Tools
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.

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 Few Of The Several Advancements In Carbide Inserts By Iscar
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.

New End Mills Coming From Iscar Can Raise Productivity While Decreasing 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.
