       3 . Hand tool according to  claim 1 , wherein the grinding-plate part comprises at least one opening in which internal threads are formed for co-operation with the clamping means.  
   
   
       4 . Hand tool according to  claim 1 , wherein the grinding-plate part on a side opposite to the grinding surface comprises an engagement part for co-operation with the clamping means.  
   
   
       5 . Hand tool according to  claim 2 , wherein the grinding-plate part further comprises at least two plate parts which extend at a first distance away from the grinding surface and substantially parallel with two opposing edges of said surface and said plate parts are arranged to co-operate with the clamping means.  
   
   
       6 . Hand tool according to  claim 2 , wherein the clamping means comprise a clamping part which, by operation of the operating element, clamps said plate parts firmly between the clamping part and a contact surface of the hand tool.  
   
   
       7 . Hand tool according to  claim 1 , wherein the metal plate at least at one edge of the grinding surface comprises a side grinding surface with an abrasive coating, said side grinding surface extending substantially at right-angles to the grinding surface, so that the side grinding surface and the grinding surface form an external corner.  
   
   
       8 . Hand tool according to  claim 1 , which further comprises a spacing piece arranged in a replaceable manner between the handling part and a rear of the grinding surface.  
   
   
       9 . Grinding-plate part comprising a metal plate with a grinding surface with abrasive coating, said grinding-plate part being configured to form part of a hand-held grinding tool according to  claim 1 .  
   
   
       10 . Grinding-plate part according to  claim 9 , wherein the metal plate at least at one edge of the grinding surface comprises a side grinding surface with an abrasive coating, said side grinding surface extending substantially at right-angles to the grinding surface, so that the side grinding surface and the grinding surface form an external corner.  
   
   
       11 . Grinding-plate part according to  claim 9 , further comprising at least one opening in which an internal thread is formed for co-operation with the clamping means.  
   
   
       12 . Grinding-plate part according to  claim 9 , wherein a side opposite of the grinding surface comprises an engagement part for co-operation with the hand tool's clamping means.  
   
   
       13 . Grinding-plate part according to  claim 9 , wherein the grinding-plate part further comprises at least two plate parts which extend at a first distance away from the grinding surface and substantially parallel with two opposing edges of said surface, wherein said plate parts are arranged to co-operate with the hand tool's clamping means.  
   
   
       14 . Hand-held tool for the grinding of surfaces, said tool comprising: 
 a handling part comprising a handgrip,    a grinding-plate part which comprises a metal plate with a grinding surface having an abrasive coating,    wherein an opening for mounting of a shaft is provided in said handgrip.    
   
   
       15 . Hand tool according to  claim 14 , wherein a mounting part is provided within said opening, the mounting part comprising a length of a profile of a C-shaped cross-section and a slide part provided therein, the slide part having a through-hole provided with an internal thread.  
   
   
       16 . Hand tool according to any of  claim 14 , further comprising clamping means for clamping the grinding-plate to the handling part in a replaceable manner.  
   
   
       17 . Hand tool according to  claim 1 , wherein the metal plate is a steel plate.  
   
   
       18 . Hand tool according to  claim 14 , wherein the metal plate is a steel plate.
