Iscar’s latest developments in parting and grooving systems

Through the work of the company’s prolific R&D Department, and prompted by the evolving needs of global industry, each year Iscar introduces a multitude of advanced new cutting tools. This desire to provide customers with the very latest, most efficient metal cutting technology is reflected in the recently launched additions to Iscar’s comprehensive Grip range of parting and grooving tools.

Tang-Grip- A unique tangential single ended insert with a revolutionary clamping method
Iscar’s Tang-Grip is a high quality, single-ended insert that was developed to enable highly efficient parting. A revolutionary secure clamping method using a tangentially orientated pocket provides pocket life three times that of any other conventional self-grip system. Tang-Grip’s robust clamping method enables machining at high feed rates and provides excellent straightness and surface finish characteristics.

Iscar’s latest Tang-Grip innovation is the introduction of highly economical blades. Tang-Grip flat top economical blades now feature four pockets compared to the previous version which had two pockets, whilst the integral shank tools feature two pockets compared to its predecessor which had just one pocket.


By doubling the number of insert pockets the advanced new shank tools and blades deliver the cost-effective advantage of half the price per pocket, when compared with other tools and blades. No other company is able to offer such an economical advantage, says Iscar.

The new Iscar’s Tang-Grip blades and tools are extremely rigid and are capable of bearing heavy tooth loads (high feeds), resisting lateral loads and delivering excellent surface straightness. The 35 mm blades, which are 30 mm longer than any other standard blades, can be used for deep grooving and parting applications.

Due to Tang-Grip’s flat top configuration, no chip obstructions are encountered under all possible machining conditions.

Covering all parting and grooving applications, the Tang-Grip range of high quality inserts are available with a large variety of chipformers with both neutral and angular frontal cutting edges. The extensive Tang-Grip range includes blades and inserts in 1.4-12.7 mm widths in IC830 and includes an easy to use clamping and extracting device.

The high-quality IC5400 and the IC808 Sumo-Tec grade blades feature an engraved ruler to assist in overhang adjustment and are supplied in standard sizes, which fit Iscar’s blocks.

Penta-IQ-Grip – A five star pentagonal parting and grooving insert for up to 20 mm depth of cut
Following the successful introduction of the Penta 24 and Penta 34 inserts, Iscar has recently introduced the latest evolution of the renowned Penta family – Penta-IQ-Grip.

As the Penta prefix suggests, Iscar’s advanced new parting insert boasts 5 cutting edges. Penta-IQ-Grip inserts, available in 2 and 3 mm widths, are ideal for parting up to a 40 mm part diameter or up to a 20 mm depth of cut.


An innovative dovetail wedge clamping system ensures very stable Penta-IQ-Grip insert clamping, secure edge indexing and rapid insert replacement. In addition, the robust structure enables the application of high machining parameters, resulting in reduced cutting time. In addition to guaranteed performance advantages, Penta-IQ-Grip provides excellent straightness and surface finish characteristics in parting applications.

Penta-IQ-Grip outclasses all other self/screw clamping mechanisms currently available, says Iscar. Also, when compared to competitors’ parting inserts that have more than two cutting edges, Penta-IQ-Grip provides double the depth of cut.

Iscar’s advanced new Penta-IQ-Grip is able to outperform competitors’ single, double, or triple-edged inserts for grooving and parting applications, says the company. Penta-IQ-Grip assures prolonged insert tool life, at least double that of single, double or triple ended parting inserts. Penta-IQ-Grip inserts are available in three sizes for parting: D22 (up to 22 mm part dia), D32 (up to 32 mm part dia), and D40 (up to 40 mm part dia). D22 and D32 mm sizes can also be used on Swiss-type and small CNC machine tools.

All inserts feature C and J-type chipformers to accommodate a wide variety of machining and material applications, Penta-IQ-Grip is produced from grade IC808G, a hard, fine grain substrate with excellent chipping resistance, whilst a TiAlN PVD coating provides impressive wear resistance.

Do-Grip – The one and only double sided twisted parting insert with no depth of cut limitation
In addition to highly efficient parting inserts in single and double-ended conventional configurations, Iscar offers a unique double-ended twisted geometry for unlimited depth of penetration. The Do-Grip ranges also include the largest choice of parting widths available in today’s market, covering all application ranges. Iscar offers a wide variety of chipformers and the most advanced grades to ensure unbeatable performance and extended tool life.

Jet-Cut – A cool answer to a hot problem – double ended inserts with internal coolant provide efficient coolant directed to the cutting zone
When machining materials such as stainless steel or high temperature alloys, the temperature near the cutting edge area becomes extremely high. In addition, this kind of material tends to adhere to the tools cutting edge, causing built-up edge. These problematic phenomena can be moderated by the efficient cooling of the cutting edge.

Although the principle of through insert cooling is now well established, Iscar’s legendary DGNC inserts, that were specifically designed for the parting and grooving of materials such as stainless steel and high temperature alloys, deliver a range of major advantages.


Jet-Cut is Iscar’s Do-Grip high quality parting insert that features an ingeniously designed internal coolant channel which passes through the insert. This arrangement ensures that the inserts body is internally cooled whilst also delivering an efficient coolant jet close to the cutting edge.

In addition to providing improved surface finish, the use of Jet-Cut Do-Grip vastly reduces or even eliminates built-up edge, especially when machining stainless steel and high temperature alloys.

Materials such as titanium, inconel, or austenitic stainless steel tend to harden during the cutting process and form long and tangled chips. The efficient delivery of coolant to the cutting zone by the use of Jet-Cut Do-Grip parting inserts improves chip formation and slashes flank and cratering rates.

A common problem in grooving and parting applications is that chips can prevent the coolant from reaching the cutting edge, thus reducing the insert’s life. Again, the unique design of the DGNC inserts enables the efficient delivery of high levels of coolant contributing substantially to prolonged tool life. Iscar now provides the most comprehensive range of highly efficient products for all parting and grooving situations.

Iscar says it fully understands that parting and grooving operations are extremely important aspects of the turning process. As multiple factors need to be considered in all parting and grooving operations, including the machine tool being used, the kind of material being parted/grooved, the required depth of cut and feed and speed rates, Iscar is now able to supply the most appropriate, highly efficient parting and grooving solution in all circumstances with the widest range of insert geometries, chip breakers, carbide grades and a wide range of tools tailored for an extensive range of machine tools.

Iscar’s ongoing research and development investments in parting operations guarantee improved performance for each cut the company says.
