I have seen this on TV for a while and thought 'hm... if it works that well It might just be worth buying".
The other day while browsing ebay I came across one and couldn't help it but I pushed the 'Buy It Now' button. A few days later I got a package on the front porch and it was finally home. Not wanting to wait I rushed out to the building and grabbed few bits that I did a pretty nasty sharpening job on before. While unpackaging this little jewel I noticed I got a free knife also. That's kind of a bad/good thing. Good because I need another knife because I lost my last one. The bad thing is it's going to probably end up in the same place as my last ones which I haven't found yet.
It came with a hard plastic carrying case and was packaged rather well. Like most things in this world today it's made of mostly plastic but it did have a few pieces of steel. It was a lot bigger than I imagined. I unpacked the machine and threw the instuctions and instructional video to the side. In about 30 seconds I already had the machine mastered. It's a VERY VERY easy machine to use (even a caveman can do it) and quite powerful. After sharpening a few bits I was quite amazed at the job that it did. After a few minutes it was time to lay my girl down for a nap so play time was over for me.
Later that night i went outside and grabbed one that had not been sharpened I decided I was going to put this drill bit thru the ringer. I basically tried to destroy this drill bit. I first started drilling multiple holes in a old piece of a PTO that I had to shorten. I must have drilled atleast 10 hole and decided that was not dulling the bit fast enough. I went outside and grabbed a brick and dug into for a few minutes and I was satisfied finally with the dullness of the bit. This drill bit looked horrible. i didn't think it was going to recover from the torture that I had just put it thru. I pulled the drill doctor out of it's case and sharpened the drill bit. After about 16-20 (you have to make a even amt of spins) the drill bit honestly looked brand new on the end.
Now it's time for the true test. I put the bit back inside of my drill press and started drilling the same PTO shaft as I was drilling before. This time it was TOTALLY different. There was metal shavings coming out there of both cutting surfaces that was 4" to 6" long. I have been told that a drill bit is cutting good if the metal shavings are long and coming out of both flutes. This drill bit was doing ALL OF THE ABOVE. I was quite amazed that something could work so well and only took me 30 seconds to figure out how to do it.
I would 1000% recommend a Drill Doctor to ANYONE that works with metal. I am very pleased at quality and how easy this machine is to use.
