Fritsch® V-Rotor P-19 cpl. carbide tungsten carbide with 1 set=3 counter blades

this rotor with V-cutting edges and fixed knives made of hardmetal tungsten carbide comminutes the material to be ground by a gentle cutting action and additionally by an impact/shearing action. Alternatively, a rotor with V-cutting edges and counter-knives made of tool steel is offered, which comminutes the material to be ground by a pure cutting action only. As an extension to this, the disc cutter rotor with indexable inserts and fixed knives made of hardmetal tungsten carbide withstands the highest stresses and offers the greatest stability of the knives. This rotor is even suitable for shredding PCB scrap with glass fiber residues. The rotor with straight cutting edges and counter-knives made of tool steel gently comminutes the sample by pure cutting stress, but can only be used for material that can be cut well and does not provide as effective comminution as the rotor with V-cutting edges. For sample preparation according to RoHS and WEEE (e.g. for the detection of hexavalent chromium) and for XRF analysis we recommend our cutting tool sets made of chromium-free tool steel.
