Has anyone tried these? Theory of its operation sounds good. Trying to decide between these or the rage 3 blade chisel tip which has a shock collar design or go with the O ring set up..
Shock collar or O-ring - both sound like issues to me with chance for failure. Why not use a fixed head? Lots of good choices.
I use rage chisel tip, but mine are the two blade version. I personally don't use the shock colllar, just the O ring. Never had any problems with them and they cut a mean hole.
