Tangential inserts for Walter boring tools

Cutting-tool specialist Walter GB has introduced a range of boring tools with tangentially-arranged indexable inserts to meet demands prevalent in the automotive sector.

Specifically, Walter says that the tools will be used to rough and finish bores in multiple steps, at higher feed rates and generating better surface finishes than those produced by conventional tools, even in applications without good chip clearance.
An additional 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.
Applications for boring 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.
The availability of numerous 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.
