1. A cutting plate comprising:
an upper side;
a first clamping trough extending from said upper side for clamping in a cutting tool;
a cutting edge for metal-removing processing;
a second clamping trough extending from said upper side and arranged coaxially with respect to the first clamping trough,
wherein said first clamping trough is arranged so that it is deeper than the second clamping trough and both said first clamping trough and said second clamping trough are arranged so that they are deeper than said cutting-plate tipper side, wherein a trough shape of the second clamping trough forms a surface that is parallel to the cutting plate upper side.
