This has me set up with a good selection of tools for my dewalt unit. Thing is the first one I tried was one of the basic saw blades and I found it did not have nearly the bite of the oem Dewalt saw blade that came with the unit. Not even for cutting holes in drywall! I am turned off by the saw blades and probably won't use them. The sanding and tile blades will come in handy though, making up for the saw blade lack of bite.
