## Questions & Answers

**Q: Hello ! i am wondering if i can engrave letters in marble with this product ? waiting for a reply as i am very interested ! thanks all the best !**
A: Hi,
Yes you can use the Dremel Fortiflex to engrave into marble. In the kit you'll get some accessories in the kit that will work in marble, such as grinding pieces, cutters, etc., but i would also consider looking at additional accessories to help achieve what you'd like to do.

Different shaped silicon grinding pieces, cutters and diamond engraving pieces would be good for this application.
