A method for manufacturing microabraders by machining a surface of a workpiece, each of the microabraders having a plurality of sides; for each of the microabraders the method comprising: (a) making a plurality of cuts into the surface, the plurality of cuts being in a required sequence around the plurality of sides to form a microabrader of a required shape; (b) the plurality of cuts being of progressively reducing depth such that a final cut is of a smallest depth of all the cuts; (c) the plurality of cuts, the required sequence and the progressively reducing depth being selected to provide material of the workpiece to support the microabrader until machining is completed.
