Review: Very good, do read my review though. - If you're looking to be able to ram your bit through the grinding wheel as fast as you can, don't get this. If you're more in tune with the current universe, read on. I've bought a couple of these, though not because the first one wore out! This should be the last drill bit sharpener you buy IF you take care of it and actually read the instructions. Very inexpensive considering no more drill bit purchases (unless you just break them). It IS often possible to sharpen a broken bit back into use if there is enough of the bit left. I have used this sharpener to do that several times. Use this on my high speed steel as well as Cobalt bits that have a standard shank. Always take any burrs off of the bit shank when sharpening. Is important to not rush or overload, then all is fine. Gives great results when used correctly. Doesn't need an "install" schmdesertcart getting its nose out of joint again. Plenty durable when not pushed too hard. Easy to get new stones and parts for. Good documentation. Great value for the money. The size is as stated again, schmdesertcart, wtf? Accuracy, well, I do not have the lab to be able to measure this but I CAN say the sharpened bits DO cut very much cleaner and faster! So empirically this works well! Never sharpen a bit so fast that it turns blue, or it is ruined. Never drill until it is blue either for the same reason. Never use the "hammer" mode on your drill using steel or cobalt drill bits or you will ruin them and possibly injure yourself. Use ONLY carbide tipped bits designed for hammer drilling with this function. This sharpener has a diamond wheel so it CAN sharpen carbide tipped bits!
Review: worth the purchase! - I love this product! I sharpened 12 drill bits in under 20 minutes and each bit sharpened perfectly like brand new! The Drill Doctor is so easy to use too! I read a few reviews, stating difficulty using it, noise was to loud, works good but difficult to operate. Bologna!!!! I'd give the Drill Doctor 10 Stars!!!!! Its quiet, no vibration, simple clean up and storage!!

## Questions & Answers

**Q: does aligning the chuck to 118 also applies for 135 degree geometry and what is the significance of the notches on either-side of 118?**
A: Yes it does. The significance of the notches enable you to alter the relief and chisel angle of the drill bit. By going + you will increase the relief angle of the drill bit, useful for high speed drilling in softer metals. And vis versa going -.  45 degrees is the correct chisel angle for a drill bit. By using the alignment notches + or - you can make the drill bit more or less aggressive. A less aggressive drill has a lower chisel and relief angle. I love mine, easy to set up and use. Hope this helps.

**Q: can the degree of angle of cut be changed**
A: Yes, you can choose between 118 and 135 degrees.  Many of the videos you can find on youtube and the video that comes with the sharpener show you how to do this.  you may want to take a look at the following links:  https://www.youtube.com/watch?v=8wWzW8BjtiM and https://www.youtube.com/watch?v=M6bC5imB31A

**Q: Is the 500X able to sharpen 13mm bits?**
A: I don't have a 13mm bit to test, however I have a 12mm brad point bit and it fit in the collet/chuck with a little room to spare. So you should be able to sharpen a 13mm bit.

**Q: What grit is the sharpening wheel that comes with Drill Doctor 500X?**
A: 180 grit which is standard.

### ⭐⭐⭐⭐ Spend the extra and get the 750X
*by G***A on June 19, 2008*

I bought this machine a few months ago. I've used it to sharpen quite a few bits, 50+ ranging from HSS to masonry. I will emphasize that you MUST read the instructions thoroughly, and watch the DVD as well. It is important to know how the tool works, and why you will ruin bits if you don't follow the instructions. To sharpen standard 118* bits couldn't be easier. This machine does an excellent job of it, and since I use most of my drill bits to drill in wood, this is the perfect angle for me. Split points can be ground on 118* bits, and I have done this with success. To sharpen masonry bits is also very easy, and the machine does an excellent job in this regard as well. Where it gets tricky, for me anyway, is in sharpening 135* split point bits. These days nearly all bits sold are this type and it's nice to be able to recreate the same angle and split point. While I have sharpened bits of this angle with success, I haven't been able to get perfect results all the time. Proper alignment is critical. Trying to adjust the relief angle seems to make proper sharpening more difficult and I would not recommend it to someone who just got his hands on this machine. The relief angle is adjusted by putting the chuck to either side of the 118* alignment slot (the + and - increase and decrease the angle). This is to allow a more aggressive or less aggressive cut. Fiddling with this adjustment seems to throw off the split point when it is being ground as well, taking off way too much material. If too much material is removed during the split point procedure, subsequent sharpening of the bit will not yield the same angle since the alignment fingers will not hold the bit from is flutes, but from the newly ground area behind the split point. It is hard to visualize this, the mistake must be made to understand it fully. Changing the diamond wheel is straight forward and easily done. The machine has a somewhat loud squeal when running, but it isn't too bad. I have sharpened broken bits with success, so that feature definitely works. Also, unless a bit really damaged during a botched sharpening attempt, it can most probably be sharpened to at least a 118* point again, though it will take a while and several alignment and sharpening procedures. I recommend the 100 grit wheel for when this must be done as it will take less time, and then a follow up can be done with the standard 180 grit wheel. The 750X has more features than just being able to accommodate larger bits, so in my opinion it is definitely worth it. I wish I had gotten that model instead, and I believe sharpening 135* and split points would be easier and faster. This is a quality product though, that I must say. **EDIT 7/26/08** After using my DD extensively during a project to sharpen a masonry bit, I noticed something that I hadn't observed earlier. When sharpening the bits according to the instructions, the machine does not put opposing angles on the tip of the bit. That is, it grinds both sides of the tip to an arrow point, and this is NOT conducive to easy drilling. In fact, I realize that I put unnecessary load on my drill using the "sharpened" bit. Perhaps experimenting with bit alignment might help, but that can just as easily ruin a bit you're trying to breath more life into. **EDIT 8/3/10** I am adding an edit to this review, mostly to address other reviews and comments about people needing to read and follow the instructions. On *MY* machine, only the 118* angle is indicated on the alignment port. There is NO mention of 135* angle, and this is why I had problems with aligning and sharpening 135* split point bits. After much experimentation and frustration, I finally got the 135* angle by inserting the chuck into the "-" slot, then putting the sharpening port at 135*. I don't know if my machine had a quality control issue, or if all the DD500X units are like this. To split the point on 118* or 135* bits, you need to align the bit at 118* regardless of the angle you sharpened the bit to. In splitting the point, it must be done carefully to avoid under-splitting because if that happens, the bit will NOT cut. For 135* bits, if the point isn't split, it really won't cut unless you're drilling into a very soft material like plastic or wood. A long review for certain, and a good machine, but not without faults. After owning my machine for a couple of years and using it extensively I feel my four star review of "very good but not excellent" is fully justified.
