Hi Geoff...not sure about a Dremel Attachment made of Dura-grit but I have a Dura-grit sanding pad that has been used and abused for over twenty years now and it is still like new, if their burrs are as good they will be well worth the money..honnestly I only use my Dremel to drill holes in projects....I use a flutter wheel (NOT a Flap wheel) to clean them up ...hope you find what you are looking for....have fun with your projects...hope to see some of them soon.
