A further benefit is the reduction of chatter, which is achieved by combining an extremely stable tool body with separate indexable-insert geometries that feature a second clearance angle – thus reducing the effective clearance angle, which is usually high for tangential tools.
Boring applications of 4xD can be achieved, while small diameters (from 24 mm) can be machined with three teeth. The square-shaped inserts can be installed at any approach angle; a face chamfer (wiper) also works at 72° and 90°, which guides the tool and helps to minimise noise. In addition, the inserts are cost-effective, with four plus four cutting edges.
A wide range of insert grades makes the tools particularly advantageous for users machining workpieces from cast iron, chrome nickels, steel or aluminium, such as turbine or gearbox housings, gears, cylinder bores, and steering knuckles.
