Fritsch® Rotor P-19 cpl. with straight knives, chrome-free steel C60W3 (1.1740) - with 1 Sa

this rotor with straight cutting edges and counter-knives made of chromium-free tool steel grinds the specimen gently by pure cutting stress, but can only be used for material with good cutting properties. Alternatively, a rotor with V-cutting edges and counter-knives made of chromium-free tool steel is offered, which also comminutes the specimen by pure cutting stress, but is much more effective. The rotors made of chromium-free tool steel are especially recommended for sample preparation according to RoHS and WEEE (e.g. for the detection of hexavalent chromium) and for XRF analysis. For all other applications, we recommend our cutting tool sets made of tool steel and carbide tungsten carbide, as these are harder and thus more resistant to abrasion.
