Walter has introduced double-sided ISO indexable inserts with RP7 geometry, providing maximum process reliability in rough turning by combining a ground contact surface with an optimized profile that has a tailored protective chamfer to guard against fracturing. The RP7 benefits from a new design that features a T land for protection against chipping, a ground seating surface, a center curve for extra cutting edge strength and a deeper chip groove that enables higher feed rates.
This geometry offers an alternative to the Walter MP5/RP5 geometry when a more robust cutting edge is required. It is particularly suited to working on applications that include heavily interrupted cuts or forged parts with variable machining depths, such as roughing steel materials.
In addition, the inserts’ Tiger-Tec Silver coating technology is said to extend tool life, thereby lowering new tool investment costs. Costs are also reduced by having a two-sided insert, providing double the standard number of cutting edges on each indexable insert in comparison to the usual single-sided insert often used for heavily interrupted roughing cuts.
The new RP7 geometry is available in the four basic shapes and in four grades including the extra-tough WKP30S for applications requiring high toughness.
