Walter is presenting its FM5/RM5 indexable inserts with jet guiding geometry. According to the German company, they are particularly beneficial to users who machine high-temperature alloys (ISO S) and stainless steels (ISO M). Excellent results are reportedly achieved in particular with duplex stainless steels. The main advantage of the new roughing and finishing inserts is their jet guiding geometry. As is explained, thanks to special channels embedded in the cutting face, the coolant reaches the cutting edge directly, underneath the chip. This targeted cooling maximizes the cooling effect and increases tool life, and at the same time optimizes chip breaking. The coating in the company's own Tiger-Tec Silver grades also reportedly contributes toward this effect. The FM5 jet guiding geometry ensures optimum chip breaking during finishing operations and the RM5 jet guiding geometry enables optimum coolant supply during roughing operations. The design of the cutting edges is also new in that the double positive macro-geometry reduces notch formation and crater wear.
Indexable inserts for ISO M and ISO S
The new Walter indexable insert geometries FM5 and RM5 have a so-called jet guiding geometry. Channels introduced into the cutting surface ensure that the coolant is directly guided under the chip to the cutting edge and a longer service life is achieved as a result.
