Review: Well-built drill bit sharpeners. - This is my second Drill Doctor. They are fantastic sharpeners. The first one was a DD 250. It is still in use after 25 years. I have sharpened maybe 300 or more drill bits with it. It still has the original stone. I received my new DD 500 yesterday. It is basically the same machine but, upgraded, and can sharpen masonry, and split point bits. Sharpened about 20 steel bits in about 20 minutes or so. Also, tried sharpening masonry bits. Takes a little getting used to but, after a couple of tries it worked great. On the masonry bits I would recommend starting with a bit about 1/4" or so until you get the hang of it before you try any smaller ones. They are a little harder to sharpen. I sharpened bits down to 1/8". I would recommend this sharpener to anyone looking for drill bit sharpener. They are very well-built and easy to use machines. Just follow the directions, and you will do fine.
Review: Easy to set up and does a fantastic job! - A VERY quality piece of machinery. Great instructions. Easy to set up. I sharpened every bit that showed signs of use in my shop! I highly recommend it.

## 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.

### ⭐⭐⭐⭐ It's a drill bit sharpener.
*by E***R on January 4, 2026*

First off, this machine is quite good.it will sharpen dull bits as good as new.the actual sharpening process is quite easy and quick.the instructions to get there are a little vague.if your grinding a 118° angle the printed instructions doesn't tell you what notch to put the chuck in to get the desired relief angle.you have to keep resetting the bit and selecting the next notch and regrinding to get the desired relief angle.for the 135°setting the instructions do tell you the notch to select. And the port to grind the split point is straight forward.i used that port on a 3/ 8th's bit it dressed the point up nicely but it didn't grind the whole flute.( Probably the bit stick- out from the chuck is the reason). Overall I'm well pleased with the machine.it eleminates the errors and guess work that come with free hand sharpening.the vagueness of the printed instructions is the reason for 4 stars.it does an excellent job and in my opinion,worth the cost of the purchase price.a d with a three year no product registration hassle free warranty the cost is reasonable. Once you get the process to get the bit set to grind down pat your in business.i recommend this product to anyone who's not looking to keep on buying bits to replace the dull ones.
