Hi all, I have a Dremel type tool (Well Aldi/Liddel equivalent lol)I recently had to cut through some small bolts on a model I'm making, No problem I thought so I got the tool out and fixed one of those small black rotary slitting type discs on to it mandrill .They were so thin I broke loads just trying to fit them on the mandrill of the Dremel. So I ordered about 25 off eBay and they where worse, Every one disintegrated while trying to cut off a couple of small bolts. Very Dangerous' I did try them at most speeds and all either broke fitting them to the Dremel mandrill or flying off in bits.... My question is what type of cutting off discs do you guys use on your Dremel or equivalent type and where do you buy them from...PS I gave up and uses a junior hacksaw.
