This rotor with V-cutting edges and fixed knives made of chromium-free tool steel grinds the sample gently through a pure cutting action.
Alternatively a rotor with straight cutting edges and fixed knives made of chromium-free tool steel is offered, which also grinds the samples gently with a pure cutting action, but can only be used for easily cut materials and therefore does not offer an as effective size reduction like the rotor with V-cutting edges.
The rotors made of chromium-free tool steel are especially recommended for the sample preparation according to RoHS (for the verification of hexavalent chromium) and for the XRF-analysis.
For all other applications we recommend our cutting tool set made of tool steel and hardmetal tungsten carbide, since these are harder and therefore more resilient against abrasion.
