I assume you mean a Dremel rotary grinder (as opposed to an engraver)? These will suffice for aggressive removal of matrix, but with poor control close-in to the fossil. If this is your goal, the selection of bits will depend a great deal on the hardness and friability of the matrix itself. For slower, close-in work, consider a vibrating engraver type tool.
Hello, this is my first time using a dremel to prepare fossils. I decided to begin testing the dremel on an enrolled trilobite with partial cephalon because I thought it would the easiest and it was already missing pieces. So far I am happy with the results, however, it's very difficult to get in...

I got my dremel and I want to prep the Ammonite in the picture. Can someone give me some advice or tip to use the tool and for that Ammonite? I will practice first with some Ammonite fragments. The matrix is kinda soft and weak.
Expand Hi there, I use dremel for finishing purpose also (removing pen marks) With the shale where i find my trilos, it works like a charm, though the flexible is a must. I mostly use the "abrasive rolls" ( like the one pictured abouve), different size.
I have recently heard on the internet that some people use dremel tools to prep fossils, particularly cleaning gunk off of echinoids and co. Is it a recommended for Echie prep, or should I use something else?
The dremel engraver and a few pics is how I started prepping (heck it’s still how I prep) make sure you post plenty of pictures of your progress and don’t be afraid to ask advice. all of us other preppers will be glad to help out! Some of the members here are artists with a prep job. Always looking for unprepped wrf material
