Drill Doctor DD750X Electric Drill Bit Sharpener, 3/32-3/4" High-Speed, Portable - Steel, Masonry, Carbide, Cobalt, Tin-Coated Bits, Adjustable Angles

So I've been trying to get through my extensive collection of bits and I have put this thing to the test for a few weeks now constantly going through starting with my larger bits. Started with the3/4 because that's the largest it will except in the holder jig, and also made sure to have the additional 100grt wheel for the larger ones and after the first few days I decided to make a change and bounce down and work on the small sizes and man I had a lot more than I thought. They have gone much easier and quickly and not having a single issue. Zoomed through several hundred bits now and I am amazed at the condition of the Wheels, both the original 180 and the 100 i purchased appear as though I haven't even used them. Quality of the wheels obviously are great. Power of the motor can be tested on those big heavy bits and they are some very hard material. But I guess I have to share the few things I don't necessarily like, or thing's I believe could be a little better, especially since they have been manufacturing these for some time now and I think they have been content with what they have and decided to leave them alone, because I'm not seeing any real upgrades since the first model came out, possibly the overall power of the motor and I guess that's what I was actually most concerned about, but I can tell you there's no worries there. But small things from the design and fit of the little tray on the bottom you use for access to change or clean up the wheel. It's a poor fit, and from difficult to get open to also allowing way more of the metal dust it throws out the bottom and the sides. To the removable access to the side view you use for splitting the tip of a bit if you choose to go that route, which also blows constant dust out of the opening when you're not using it, but this is probably my biggest complaint about the entire thing. If you want to split the tips you need to do more than just jump from the normal sharpening process and like you have seen in videos where they sharpen a bit and take it directly to the side access to split it, but it's not properly lined up, it's not exactly a precision machine, and for straight up sharpening needs it functions for me just fine. I have to spend a lot of time with each bit if I'm splitting it from the holding jig i have to manually tweak the depth of the bit using nothing but visually putting it in and out of the side access and adjust it until you are not going to hit the Sharp edge of the bit and not go too far to the back of the edge and take chunks out of the bit leaving lots of burrs on them to clear up. I think it could certainly benefit from some possible upgrades to the adjustments and the slides that you adjust to go from 118 to 135 degrees is in need of some improvement, it can be really hard to move even after you loosen up the screw in the middle of your trying to get it changed. It hangs up somewhere and I can't see where. I think compared to the much more expensive machines that I would take this one every time, but I wish they would work on the fine tuning stuff, and simplify the overall design making it look like and function more like something you would put on your bench and leave on your bench and help keep your bit collection nice and sharp and not in the bag it comes with, and tucked away in a drawer somewhere and it gets pulled out once a year and you are not going to enjoy it as much, I would probably have zero complaints if it wasn't for the amount of bits I'm having to get through because I have procrastinated and I would like to have it benchtop constantly touching up my bits before I return them. This has been around long enough for it to be a little further refined and less moving it around to make adjustment, and constantly turning it from one side to the other, and make it more like a permanent piece for the shop and less like a portable sharpening device to take with you. It just needs someone to look at it and imagine it will be sitting in the shop for continuous access and easy to keep caught up. This is a good test for this thing, but still have to admit that it doesn't fail any tests, and I don't regret my purchase, but it was a tuff decision for me because I have so many bits that I use and have so much invested, I was serious about to purchase a machine for more than a thousand dollars and I don't think I would be unhappy with that. But I've been looking at these for some time and I thought it was a good idea to get this one for the value, and I could have passed it over to my son in his own shop if I could see a reason to spend that much more money, and I have to be honest, I think I made a great choice and I would recommend it to anyone.

I love my drill sharpener. Works as advertised. Easy to use. Saves all my drills. And saves me a ton of money. In my opinion, this is the best homeowner sharpener on the market.

I believe that having a bunch of dull drill bits lying around is a common trait among hobbyists like me. I have occasionally touched up a bit using honing stones, with mixed results. It can be done but requires some practice or raw talent.After watching several videos and reading through the paper instructions provided with this machine, I set it up for 118 degree points and tried sharpening a very dull 1/4" bit that I found in the street many years ago. The business end was completely trashed when I started. The Drill Doctor did a respectable job of putting a sharp, symmetrical point on that bit in less than a minute, so it is now usable. I went on to several non-expendable bits from 3/32 to 1/2" that had dull or chipped points, and they all came out well too. I was not particularly pleased with the job it did on a 19/32 industrial bit that I had bought at a surplus store - The grinding wheel seems to be taking off material where it shouldn't, and it didn't produce a good chisel point in the center. It's probably a matter of tweaking the setup or my technique so I regard that as forgivable for now, but I am not yet convinced that the 750x will really work right on bits larger than 1/2".Here are the main points I like about this tool:- Reasonably easy to set up and use,- Very fast, though the motor is not very strong. You have to take light cuts.- Consistent results if you use it in a consistent manner.I'm giving this item a one-star penalty for the following quality control issues:- The Material Take-Off adjustment knob on mine is bent downward. It seems to work correctly, but doesn't look or feel right.- There was no instructional DVD included with mine, even though the plastic case has a provision for it, marked "DVD Location." The video content is available on YouTube, so this would be a minor issue for most people.In summary this is a good value. I expect it to save a lot of grief and some money in the long run.
