Dylan I have had the Wecheer for 2 years with the reciprocating flex shaft and it sure has its place like everything else in the shop. It takes wood off like nothing else.
I was looking at the Arbourtech chisel too but it was to heavy on my hands ,but it is the best.
I use a lot of hardwood and it seems to get hot around the handpiece when used for a time of 10-20 min.I also have the set of Flexshaft chisels and when I use the big ones it gets hot more quickly. but I work it hard :-) overall I like it very much "no dust" I hope this helps
