Insert accommodates low and deep cut depths

By combining two different geometries on the same insert, Walter has created the NRF indexable insert for simultaneous heavy duty rough- and finish-turning applications in the same setup.

The insert can be applied on both low- and high-alloy steels and with the same tool, effectively halving the number of geometries users may need.

In addition, because NRF features a strengthened double groove at the main cutting edge, the doubled chip compression generates short chips.

The V-shape chip-forming area at the cutting radius leads to optimum chip breaking at low depth of cut.

Available in five basic shapes - CNMM, DNMM, SNMM, TNMM and WNMM - and in a variety of Tigertec coatings, NRF inserts can accommodate machining at low (0.8mm) and deep (15mm) cut depths, and cutting forces can be reduced because the curved cutting edge generates a soft flow of swarf.
