I was cutting off some extra resin from a figure when the cutting disc went flying. The screw came off holding it on. I've only used the selection of things that came with the tool and have never bought any new stuff.
Should I try and find a replacement screw or just buy a set of cutting discs that come ready to use. I do not know the names of the parts, etc that go into the tool.. MicroMark and model-expo seems to have sets of cutting discs, polishers, etc that I can buy.
Not sure what you mean by Craftsman Dremel. Was it a Craftsman brand or a Dremel brand? I have noticed a lot of quality problems on aftermarket cutting disks. I have never had a real Dremel screw back out, but the disks sure break a lot.
The best cut off wheels (and thats what these disc's are) are the fiberglass reinforced ones. They do cost more than the standard (but thinner) ones. I've had many many a cutoff wheel shatter on me when cutting metal. Reason I went to the fiberglass reinforced wheels. All they do is wear down. The main reason the standard wheels shatter is application of off axis force unintentionally applied. If you keep the wheel tool true to the material, and cut being done and do not use too much force, the standard cut off wheels work well. Being thin they are great for cutting resin, tho even then I've been able to make them shatter.
To get a replacement screw and they are interchangeable with most dremel type tools, the OP needs to get a new cutoff wheel set, or just scrounge through his dremel set (if he got a complete kit) and use that. Like use one from the buffing wheel.
The No 1 reason I've had screws back out is that I did not tighten the screw down enough in the first place.
One other thing here.... I also went to an air powered dremel tool. It is far SAFER !! If it catches it will stop and not *grab* and try and turn the tool (and the victims hand) Also you can run them at lower speeds easily and to me, it has better control. Once I got one, I gave my standard dremel tool away. (one needs a good compressor tho)
