Microstructure & Cutting Edge Comparison
Images 1 and 2 illustrate white particles that are primary hard carbides and black areas that are the softer matrix.
Fine grain size
Superior cutting edge
1. Smooth-Kutt E-HV-975 microstructure shows well rounded, evenly distributed carbides within a very fine grain size. These characteristics create a cutting edge that continues to give a smooth cut to fibers even after the edge starts to wear.
2. Conventional HSS microstructure shows a large array of irregular carbides unevenly distributed in the soft matrix. This creates severe micro-chipping that causes fibers to be only partially cut. This results in the material tearing instead of cutting evenly.
