I've been using for plugging the Wolfcraft 3750000 Universal wood dowels set that I find fundamentally highly recommended. However, the weak point is supplied depth stop, a simple steel ring with grub screw, which must be turned into the chip removal - fits badly askew, is easy to move and scratched while the good drill. In addition, the 6 and 10 are missing in diameter. Therefore, this set was needed. These deep stops are actually to be used as such (ie, you can also really handy drill until it stops to without fear around the drill, and you can drill several holes to without readjust in between must). The execution could surely be finer still a lot, and (put half closed, tightening with an Allen key), the handling is not the most comfortable. These small Unfeinheiten you like to take but in favor of even smaller price in buying, especially as they affect the precision of the result in any way.
