They are sick, I got to use the roto-hammer at our customer appreciation day. The rep from De Walt let me take it over to the warehouse where we needed some more anchor bolts for a wall. Went 6" deep in the foundation and through the existing plate with ease. He was also packing a very high dollar diamond tipped massonry bit. (haven't ever seen one till he whipped it out?)
The rep from Makita said they will also have a really high end set out very soon.
