For the price you get a reasonable and qualitatively adequate tool. The labeling of the size and the brand is fine to read on the shaft of the drill and the blade / cutting are brand still really razor-sharp - the fingertip test proves it. The drilling results are using a Ständerbohrmachine or a drill press, as might be expected, good. The serrations on the edge of the drill carve a material such that there is a clean Bohrrand (no fringe). In freehand applications Zentriespitze helps to prevent slipping on the workpiece, but again you need a calm and steady hand if you want to get good results. Since the package unfortunately occurs only in blister and / are no protective cap for cutting head, you should, if you want to have long friends at the tool, worrying for gentle storage. Furthermore, the stem size was on my blister expressed as 8s, real, it was a 10 shaft. The service life of the tool can be increased if you are not quite as sharp drives the drill into the material and blows it between several holes and allowed to cool.
