We have just finished adding onto our home. 2 Bedrooms and a Bath.
Before I started this project, I bought the 36 volt Dewalt Cordless Tool Set.
This included:
7 1/4" Circular Saw
1/2" Hammer Drill
Sawzall
36 volt Snake light
Charger and 2 Batteries
Throughout this project, the entire tool set has performed flawlessly.
The 36 volt Drill would cut those holes and not break a sweat. In fact, I did use several wood bits for wiring and a larger size for water piping through the wall studs.
I also used it to drill 1/2" holes in the concrete to install anchors.
Very happy with these products.
