Abstract: In a negative mould (1) closed by a lid (3), hard material abrasive grains (5) are nickel-attached to the peripheral inside surface. The negative mould (1) contains, in addition to the outside contour (4) of the tool to be manufactured, also the surfaces for the location bore (7) and the end face locations (7′) of the said tool. Subsequently the inner space of the negative mould (1) is completely filled with a casting mass (6) interspersed with solid particles (8) and the said mass allowed to harden. The mould (1) is removed by machining or etching. This process permits the inexpensive and economic manufacture of tools coated with hard material abrasive grains.
