## Questions & Answers

**Q: Only 2 of the 5 collets fit the tool, and none of the accessories fit the collets. Can I purchase additional collets that will fit?**
A: The collets are fine. When new they are a little tight but with a little finesse the included bits for very well. The smaller collets are for bits with smaller diameters like 1/16th drill bits and such.

**Q: Will it work in a mouth guard?**
A: I bought it to help with the edges of my partial mouth appliance, so if that’s the type of thing you’re looking for then, yes. It’s one-hand-held and small enough to control easily. It has three power levels and many tips.

**Q: What size drill bits does this use?**
A: The rotary tool comes with 4 collet sizes（1.6mm，2.3mm，3.0mm，3.2mm) to fits different suitable accessories and it is easily changed

**Q: Can I use it to smooth out my toenails?**
A: Yes, it will be very effective.

I have only used this drimal twice a it quit working .. The customer service was prompt in handling the issue. I highly recommend this Dremel it's easy for me to use do to the arthritis . it's a Buy.

### ⭐⭐⭐⭐ Good for the price
*by E***E on July 16, 2023*

This is a very useful and easy to use tool. I wished i could change the spinning direction. Depending on your task and whether you're right or left handed, this option would be useful. A mild annoyance is that you have to click through all the speeds in order to turn it off or reach the fastest setting. Having a designated on/off switch and the speed selector. Still, for the price, this is a neat little device
