Question about Dremel 3000-15

Yes, it works with small discs (like grinders), it's not very clean but it works.

In order to cut plexiglass you will need the Dremel 561 bit or an equivalent. It is not included in this set. You may also want the 565 attachment to make sure your cuts turn out straight.
