Dewalt dcs 387 18v

This is a test of the dewalt dcs387 recipicating saw, it&the 18v version with a 5.0 am battery. I&using a new dewalt blade dt99554 bin 4/6 Tpi i really like this new blade cuts grate very fast in most types of wood. I&cutting a rafter that&45 mm thick og 300 mm wide. The wood is dry and the blade is brand new. This is not a brand new dcs387 I&had it for about a year but is comparing it to the new dewalt dcs388 flexvolt, and the dcs387 18v is of cause not as powerful but more important the device vibrates more than on the flexvolt version #dewalttools
