Once you get used to the setup, quite easy to use. Much better to sharpen drills than to be constantly replacing them. Getting the setup correct is the most time consuming part but the end result is worth it. Got the storage case too. Definitely a plus because I'm not sharpening drill bits every minute of every day.

Instructions even, with video, are not specific & don't go into enough detail, leaving a novice with having to figure out how to operate it on your own. Once you figure it out, it does sharpen the bits. I am not sure how long it will last and the replacement grinding wheels are fairly expensive.

I've read several reviews and people complain it doesn't work. I own the 750 model. First it is important to watch the video (available on Youtube) to see how to use it properly. The first drill I did I screwed it up. But after paying attention to what I was doing and using the machine correctly it has worked flawlessly. After 20-30 bits, especially large ones, 3/8 and above, I turn the grinding stone around. It's extremely easy to do and I am wearing the stone down evenly. I spoke with another machinist friend of mine and he recommends changing the stone when your bits began to blue when you sharpen them. He said usually after 475 to 500 bits. The smaller the bits the longer the stone lasts. Obviously, blueing in any metals is unacceptable especially in drill bits. Clearly time to replace the stone. The grinding wheel is inexpensive compared to buying a 64 drill bit set, especially titanium or cobalt. I have sharpened both these types of bits with excellent results. Also, lube the guide pin with a little oil or petroleum jelly and the chuck rotates easier.Read full review

This sharpener works well and is easy to use. I have sharpened around 100 bits with it so far; many of them were 1/2" and larger. When used to split points (which I would recommend on all bits for metal), it can be hard on the machine (bogging) on the larger sizes particularly 1/2" and up and any that did not already have a split point. I would recommend using a shop vac in place of the 'grit tube' that is supplied with the machine when either sharpening large quantities of bits or bits larger than 1/2", for the heat generated is most likely detrimental to the machine's front bearing and motor. The cool air circulated through the machine via the vacuum really keeps the machine cool compared to how hot it will get without, and it has the added bonus of cleaning up all the grit. For what this machine costs, it's worth buying if you have a bunch of bits to sharpen vs. buying new, particularly larger bits. The wheel is reversible, so you can get double the life out of it before replacing (after 100 bits, I am considering reversing it). I would assume based on how much, and carefully, that I have used it, that it would last up to 500 sharpenings of mixed size bits before either the bearings or brushes would be consumed.Read full review

Very good product, I previously had purchased the 500 model used it in my work as a construction millwright, with very good results. I have used this model the 750 now with equal results, just wish they had a 1 inch capable model as well.
