Some Details of Diamond Grinding Drill Bits
Practical Application
Warm Tips
- For new tools it is necessary to try the tool for runout during installation and to adjust it until it does not runout before use. Otherwise the tool will be worn out quickly.
- Be sure to cool the water. In the case of dry drilling, the diamond on the tool head will be graphitized by overheating and will soon be worn out.

This was my first time purchasing these Dremel Diamond bits and they last longer than I expected. The variety available in this set is awesome. They are easy to use and great value for the money!

For the price I expected poor performance but they worked much better than thought they would. And as a bonus they were delivered on time.

I had to grind some hardened steel and these bits effortless did the job. Take your time and let the bits do the work for you. Apply minimal pressure and do not use any sort of lubricant. Spin at the fastest speed that you can. Depending on the hardness of the piece that you are grinding you may need to use more than one. I ended up only using two but every job is different. I highly recommend these bit and will definitely be buying another set or sets to give as gifts. Happy grinding!

Bought these to play around with rock polishing and shaping, and they're working really well. I've worked down five or six quartz and quartzite stones so far using just one burr bit, and that bit is still going strong.Keep in mind that 60 grit is going to leave your pieces very rough and is ONLY for getting everything even, roughly shaped, and relatively leveled out. If you're working with smaller items, don't use these to work your piece down to the size you want your finished product to be; leave room for all the other polishing steps that will follow.I don't know what the rules are for woodworking, but with stone polishing, you have to keep your piece constantly wet to prevent overheating your machine and/or melting your burrs. You can get or make a system that drips down as you work, or you can just have a container of water beside you to dip your stone into, as well as your burr bit occasionally as you're working, as that will remove debris and keep a consistent texture.

So these bits work great, although I initially had issues with them fitting in the collet of my rotary tool (non-dremel). The shafts were too thin (1/8") and I wasn't able to tighten the collet down quite enough to hold them. Luckily, I have an older Dremel single-speed lying around, and found the collet from that worked fine.Any other bits I have bought that say "will fit Dremel" have always fit my rotary tool, so I'm not sure why these didn't.

The grit is a bit too thick for doing finer work. Maybe I missed what the grit was.

I used one for the champhering on this slate and it held up well with water, They are better than I expected for the price, figured each bit would be a 5-minute throw away, but one did the job and it is still usable
