hi, I just received the drill doctor 350x for Christmas. all I can say is " wow" I had 3 very badly burned and rounded over bits that I tried to drill through some hardened steel with. the bits were to a very nice set I have so I didn't just want to toss them and buy new. well some one was listening when I was grumbling about them and I got this.
its very easy to set up and use. no numbers to line up, just some very feelable marks for aligning. all 3 bits took sharpening routines as they were that badly deformed. when all done, they were nice and straight across the edges and very sharp. in the box was a dvd showing you how to use the tool and also a very scannable print book. for English you just need to scan the first third of the book as the rest is Spanish and French I think. so that's it. it really does what they claim Jim [Non-text portions of this message have been removed]
