like all the tools offered for hobbyists, for surface mounting is not suggested in the advertising combination of easy handling with perfect results possible. In contrast, already speaks that same special dowels offered to compensate for possible Bohrversatz with this part. Compared to other -also preiswerteren- commercially existing parts it offers both positive as negative: - Simple drilling depth setting, but not for cordless drills suitable - Better drill guide for drilling of board edge but not on the board surface. The soft foam rubber of the associated base (in my view would be a rubber pad with maximum Shore hardness better) and the marking tabs on the sides of the base plate (which interfere with applying the foot plate on a guide rule / board) make the results of drilling very dependent on the eye and the skill of the user. Nevertheless, I would recommend this part with a clear conscience, because it does the job in the Great and the whole. Together with an additional competition selling part results in an optimal working. The deduction of points is due to the false advertising promises! After further tests on harder woods (beech, instead spruce, pine or chipboard), I regret my assessment revise: for this tool is definitely not suitable! For this, the main guide bar would be much higher and more massive and can be fixed to the foot plate. In the present embodiment, a tipping of the anchor-Kings over the board edge is inevitable if a greater effort is needed for drilling. The result is correspondingly poor. Maybe something can be remedied drill employ the go through hard wood like butter and to use especially lightweight and compact drills to keep the effort low.
