Following the successful introduction of the cost effective Penta-IQ-Grip 5 cornered D40 inserts, new users quickly appreciated the inserts’ performance, extended tool life and the resulting levels of profitability.

Sandvik Coromant is a Global leading supplier of cutting tools, tooling solutions and know-how to the metalworking industry. With extensive investments in research and development we create unique innovations and set new productivity standards together with our customers. These include the world's major automotive, aerospace and energy industries. Sandvik Coromant has 8000 employees and is represented in 130 countries. We are part of the business area Sandvik Machining Solutions within the global industrial group Sandvik.

The hob is registered in accordance with DIN3968 class B, but generates a gear quality extremely close to what can be expected from a class A hob. Insert changing is quick and easy, and yet features modern wedge-clamping technology for positional repeatability and the groundbreaking iLock interface for high precision and stability.

A dovetail wedge clamping system is designed to provide 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. The system is designed for enhanced straightness and surface finish characteristics in parting applications.

The successful CoroMill® 176 range of full profile hobs for spur gear and helical gear milling has now been extended by Sandvik Coromant to incorporate larger module 9 applications.

Hobs can be supplied with standard carbide inserts for generating gear profiles in accordance with DIN3972-2, although Custom Made options are also available for specific profiles with, for example, addendum modification, protuberance, tip chamfer and tip relief. Insert grade GC1030 with multi-layer coating is offered for high levels of wear resistance and edge line toughness in ISO P (steel) gear milling operations.

Prompted by global demand, Iscar has now expanded its Penta-IQ-Grip line with the inclusion of 22 and 32mm diameters. Both inserts are 2mm wide and are ideal for parting up to 22 and 32mm bar diameters.

The new 22mm inserts feature a “J” type chipformer, whilst the 32mm inserts feature a “C” type chipformer and both sizes are available with neutral, left- and right-hand frontal edges. The new Penta-IQ-Grip inserts are mainly intended for efficient parting-off.

Penta-IQ-Grip inserts, featuring five cutting edges and available in 2 and 3mm widths, are designed for parting up to a 40mm part diameter or up to a 20mm depth of cut.

CoroMill 176 was initially launched in modules 4-6, however, it soon expanded to incorporate modules 4-8, and now to module 9 (module is the pitch diameter divided by the number of teeth). Available for roughing, semi-finishing and finishing operations, this innovative assortment of tools offers a solution for both hobbing machines and multi-task machines/five-axis machining centers.

• Innovative dovetail clamping structure ensures a most stable insert clamping • Excellent straightness and surface finish for parting applications • Clamping mechanism enables quick and easy cutting edge and insert indexing • Superior insert lifetime, twice the life of a double-sided insert • Enables machining at high machining parameters, resulting in reduced cutting time • C and J-type chipformer for a variety of machining and material applications • Produced from grade IC808G; a hard, fine grain substrate with excellent chipping resistance, TiAlN PVD coating. Provides high wear resistance • Size 22mm and 32mm can also be used on popular Swiss-type and small CNC machine tools

First introduced 18 months ago, CoroMill® 176 is an indexable insert hob that can reduce cutting time by an impressive 50 percent, largely through the application of cutting speeds up to four times higher than conventional high speed steel (HSS) cutters and a large number of effective inserts. The cutter offers a full-effective design compared to the half-effective designs on multi-segment hobs with tangentially mounted inserts. Furthermore, tool life is up to six times longer, which means machine downtime is also reduced in direct proportion. Another advantage is that HSS tools necessitate the purchase of several tools, which must be monitored closely due to the need for re-sharpening and re-coating.
