All I can buy for my Crapsman is the anti kickback, I'm an idiot and can't run a saw chains so I use my dremel and grind off all of them. It actually works like a chainsaw then instead of either a wood polisher of a fire starting device. So far I've done it to about 12 chains and no breaks or adverse effects yet, just gotta be careful and not grind into the actual link.
Question related to your statement. Where/what do you purchase grinding wheels that will last more than a couple of minutes at a cost of $4-5?
Have had a Dremel for many years, and it is used very little. I could occasionally use it to enlarge a hole slightly and a number of other sm jobs, but gave up because of the cost of their wheels, and how soft they are.
