New RP7 geometry with Tiger·tec Silver from Walter tackles the toughest rough turning applications

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 specially designed T-land for protection against chipping, aground seating surface, center curve design 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, and is also ideal for roughing steel materials.

In addition, the inserts' Tiger·tec Silver coating technology extends tool life, thereby lowering new tool investment costs. Costs are also significantly 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 typically used for heavily interrupted roughing cuts. These features, in conjunction with the new optimized geometry, make the new RP7 inserts the productive solution for rough turning applications.

The new RP7 geometry is available in the four basic shapes; CNMG, SNMG, TNMG and WNMG, and in grades WPP10S, WPP20S and WPP30S, and now in the extra tough grade WKP30S for applications requiring maximum toughness.
