I had a Dewalt Flexvolt DHS790AT2
I used it to cut baseboard, rebuild split jamb door frames with a different mounding, cut luxury vinyl locking floor planks, cut 2x4.
It was used outside, under a carport, for 9.5 months on mostly battery power. This was done to repair flood damage to my older brothers house.
I hated the dust collection. It was hooked up to a a large Ridgid shop vac sometimes and other times a large craftsman shop vac. I found I couldn’t keep the weird rubber diaphragm open enough to capture saw dust. To much suction the diaphragm collapsed, and not enough suction dust was sucked up.
During this time I used the Festool TS55 to make rip cuts for trim at the top of ikea kitchen cabinets, and to cut side panels for the ikea kitchen cabinets, and to cut Corian for the shower and tub surround and window ledge. The dust collection on this was awesome.
I’m looking for another miter saw myself for some work at my home. I think if all else fails I’ll cut some floor for my own place with the TS55. Perhaps i can do the baseboard with a coping saw.
