So bought the Drill Doctor 500X, read directions, watched 2 videos on line and was off to the races and I am not in the trades. So first bit I did, I decided to make a challenge so I used my belt grinder to flatten it completely to see if I could get in reshaped and split again with the device. Once I accomplished that, took about 20 minutes till it was like new, I really starting flying through dull bits. I like to suggest practice using larger diameter bit when you first get it , this way can really see what's going on with your surfaces, chisel, heel and cutting edge, etc and you'll see what your doing wrong quickly and can adjust technique [like not clamping on thinnest part of bit, very important, hehe]. So my 1st bit took 20min to fully reshape and split the point on and test it out and I felt really comfortable with the sharpener after that. Had it 2 days and already I can touch up a bit in 2 to 3 minutes and completely reshape a badly damaged one in less then 10 minutes. Probably did a hundred bits by now and average maybe 2 failures in 10 that Im not satisfied with and will redo them but that's easy, re-clamp, align and sharpen, done. Haven't found a bit I couldn't sharpen yet using this. Only bad part is I'm running out of dull bits already and was finding it almost therapeutic sharpening drill bits with this in garage...maybe have to call some friends and offer to sharpen their bits for them just for fun, lol. Seriously though, good product, well built, easy to use and does amazing job, thanks Drill Doctor! Review: Excellent tool - As a retired Tool and Die maker I missed access to the great machinery I used to use to make things, so I got a small shop going in my basement with a lathe, mini mill, drill press, etc. At work we had a beautiful Black Diamond drill bit sharpener the size of a kitchen stove which really spoiled me. As my drill bits got dull with use I really missed the sharpener and decided to try the much vaunted Drill Doctor. I gave you the preliminary stuff here so you would know my background on this. I expected poor results from this small machine. I was surprised. Very easy to learn but its method of operation is somewhat similar to the fantastic tool I used for decades at work so my learning curve was probably faster than someone who is not a machinist or toolmaker. Still, the instructions were clear and frankly if you are using your drill bits enough for them to require sharpening I assume you have your wits about you. Admittedly the bits came out looking a bit sorry...not like the professional machine at all. There are and will be scratches and gouges on the ground surface (by easing up on the pressure you apply for the last few revolutions of the bit you can minimize this but it will still be present). But I am a results oriented guy. The purpose of a drill bit for me is to drill a reasonably accurate non wandering hole in a piece of metal. The somewhat sorry looking bits worked perfectly! I was impressed. IT DID WHAT IT WAS SUPPOSED TO. I have read reviews here where people complain of the finish of the sharpened surface, they are correct BUT was the formerly dull and useless bit now sharp and useful? Yes it was. Don't lose sight of the big picture....no one wants to be in the middle of a job where you need to tap or ream a hole and you find your bit is dull or the tip broken off and the last thing you want to do is go to the store, if its open, to buy another bit only to find they are out of stock on that size and besides that the bits they have are cheap imported junk. I have gone through my entire fractional, letter, and number bits and sharpened the dull ones with this Drill Doctor without any regrets. It will not do the tiny sizes since they wont fit in the holder, but those tiny sizes I keep several on hand since they dull fast and break faster! Has held up well so far, If this tool is ever lost or destroyed I certainly would buy another, probably the same model. ## Features - SHARPENS COMMON BIT SIZES: Handles standard twist and masonry drill bits from 3/32 to 1/2 inch.

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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ easy and fast, gave new life to dull bits, working great *by S***E on April 8, 2022* Ok, I probably have well over 200 dull/damaged bits that been amassing which I been meaning to sharpen but doing it by hand or belt grinder was hit or miss with me.

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. ## Frequently Bought Together - Drill Doctor DD500X Twist Drill Bit Sharpener - 3/32" to 1/2" - Electric Sharpener - High Speed & Portable - For Steel, Masonry, Carbide & Tin-Coated Drill Bits - Adjustable 118° or 135° Angle - Drill Doctor DA31320GF 180 Grit Diamond Replacement Wheel for 350X, XP, 500X and 750X - Drill Doctor Large Bit Chuck Sharpen 3/32" to 3/4" Bits for Models 500x, and XP.
