1) Thanks to the paint around the bit holder has not properly fit the angle gear in the bit holder of the battery Bohreres. Have ground away the paint with Key files, however, the edges are slightly rounded. That really bothered me.
2) The product description is flawed. I probably would have looked around for a stronger angular gear for this project, if I had known the following:
Max. 400 revolutions
Max. 13 Nm torque (very little drill out the screw)
Use Max. 10 mm Drill in wood and stone and max 6 mm drill in metal.
After I'm not really progressed with the screwdriver, I hung the angular gear unnerved to a drill (approx 1/3 the full revolution). This has the gear well weggesteckt although guaranteed investments more than 13 Nm of torque and over 400 turns. The screw lies thus very slow (more than scrape drilling) boring, though I had bought new, expensive drill bits. Once I was so severely hooked (with 6mm-drill) that it has torn my gear out of his hand. Does it also survived, although at the moment a lot of equipment more than 13 Nm.
Product is ok for the price. Guess there's no better in the price range.
