Iscar is launching Penta 34 carbide inserts with a brand new PB chipformer. The PB chipformer features a single cavity utilizing a positive rake, neutral shoulder angle, and a honed edge. It is actually a C-type chipformer with a different frontal edge.

The new chipformer was devised for machining soft materials. It is an fantastic solution for parting bearing steel and other exceptionally ductile materials. It can be used at low feed: 0.03 to 0.10 mm/rev.

The combination of the new chipformer and IC908 grade provides incredible chip breaking and tool life results. The Penta 34-PB is available in a 1.5 to 3.0 mm width range, made from the functional IC908 PVD coated grade. The brand new family advances the application range of Iscar's most cost effective grooving and parting PENTA 34 carbide inserts. The Penta 34-PB, when stacked up against to a competitor's cutter, is a leading solution for machining any soft and ductile material.

Iscar's Upgrades for Parting

Iscar has developed a completely new family of reinforced Tang-Grip blades for the popular TRAUB (TNL and TNK models) and INDEX (MS18C model) turn/mill machines. These blades, due to their reinforced composition, can be utilized in long overhang. Only the part of the blade essential for penetration (cutting depth) has a reduced width. The rest is thick, which provides enhanced rigidity and stiffness. These blades are an superb solution for parting and grooving in between the main and sub-spindle of turn/mill machines. The single-ended insert has a incredibly rigid clamping and therefore provides a extremely important advantage over any other system.

Further additions to Iscar's Grip family are Do-Grip carbide inserts fashioned from the cutting edge Sumo Tec carbide grades: IC807 IC808 and IC830. The completely new Sumo Tec grades unquestionably increase insert life, due to the utmost advanced coating technology followed by a specific surface treatment. This also provides enhanced tool life due to decreased surface stress and an uniformly coated top surface. The even surface contributes to continuous uninterrupted chip flow, less produced heat and less friction. The new process improves toughness and chipping resistance and thus reduces friction and built-up edge. This in turn enhances and prolongs tool life at expanded machining conditions for all types of work piece materials. The new PVD process is composed of Iscar's AL-TEC coating technology, employing the unique surface treatment.

Iscar's Chip Splitting Inserts
Iscar's revolutionary HM90 APCR 220605-CS grooved carbide inserts put an end to chip clogging obstacles in rough milling of aluminum, where chips can pile up. They are a part of Iscar's growing Helialu HM90 line of inserts tailored specifically for aluminum milling. With 2 grooves pressed into each polished cutting face, the inserts split aluminum chips into a amendable size for easy, reliable evacuation despite the application's characteristic immense chip volume. The 22 mm inserts, each with two edges, are designed to magnify metal removal over the full range of aluminum roughing conditions, from high power/low speed to high power/high speed. They work particularly well with Iscar's new HM90 EAL/FAL...22 aluminum rough milling cutters. Besides dependably clearing chips, the inserts conserve power and reduce chatter in long-overhang setups. The inserts feature a cavity on the bottom to be certain correct mounting in cutter chip pockets furnished with conventional spring pins. For maximum chip control, Iscar advises using the HM90 APCR chip-splitting insert only in cutters with an even number of flutes.
