The invention relates to a soil or ground processing tool comprising an elongate body, wherein a working element made of hard metal is arranged on the front end thereof. Said inventive tool can be improved by the fact that the hard metal contains at least one hard material phase, e.g. WC, and a binding agent made of nickel/chrome or cobalt/nickel/chrome. The optionally added amount of chrome corresponds to 0 0.9 wt. %, preferably between 0.1 0.7 wt. %. The cobalt/nickel/chrome binding agent comprises 4 - 20 wt. % of the entire hard metal and the cobalt/nickel ratio is 90 Co: 10 Ni - 10 Co: 90 Ni, preferably 70 Co: 30 Ni - 50 Co: 50 Ni. |
