For context, I’m a seasoned woodworker and always evaluate tools with the price in mind. This seemed like a good deal and in fact when it arrived, it looked and felt like reasonable quality for the price. Unhappily, the first bookshelf I drilled was off from side to side by almost 3 mm which would make a really wobbly shelf situation. It took a while to figure out what was happening, but I finally realized the metal bushings that guide the drill bit are so soft that they cored out from contact with the bit even though I was cautious to not put the bit in under power but to get it in the bushing and aligned before drilling. Still, the bushings started angling immediately. So when you then use those angled bushings to set the pin for the next series, it’s off by a little bit. Then the next is off by a little more…. By the time I drilled holes up and down a 6’ high shelf, the bushings were out of square, the holes were 3 mm out of alignment, and the shelf sides were firewood. Back to the drawing board and this goes in the trash, I’m afraid.
