I got this Milwaukee M18 heat gun for Christmas . I used it , For the first time the last 2 days , on outside corners of cove base. It is awesome. The weight of the battery makes it very steady when setting it on the floor.
I used it for 2 days doing outside corners,
the battery was still up to 3 out of 4 bars.
But it’s a big ( 9 amp hour) I was using.
It doesn’t blow out as hard as my electric one,
So you put it closer to the work piece.
The heat is pretty much instant.
