Review on Enhance Precision and Efficiency with the Drill Doctor DD500X Drill Bit Sharpener by Scott Carlile

Received my Drill Doctor 500 today and sharpened about 50 bits. He didn't lose strength or make a mistake. As many others have said, read the manual and watch the video before using it. The video shows the actual product and installation markings which cannot be shown in the manual. A few things I learned for ease of use, firstly the manual says to count the number of turns on the chuck. I have found that the grinding wheel is easier to hear and if it makes very little noise at full rotation the bit is even on both cutting edges. Second, if you have bits like mine, you may need to level and sharpen 3 or 4 times to get the right edge. This isn't the machine's fault, it's the sharpening of the blades on a grinder. I would recommend this to anyone looking for a quality bit sharpener that is easy to use and gets the job done perfectly.
