Dewalt DCS570N B4B19 I bought a saw, they gave me a 5 amp battery as a gift. I also bought a charger. Actually a thing, before there was a network dwe23650. It cuts like clockwork, the native disk shaggy edge, under chipboard is not an option. I sawed 50 boards 50 * 100 with a native disk and dissolved 10 boards 50 mm. On this battery sat down, but an hour of charge and again in the ranks. Working on weight is not very convenient, weight still affects, but working on emphasis is just a thrill. I look towards the 996 drill.
