It's a good tool and worth the cost.

Would Recommend

My first experience with this tool. I was reinforcing a 4"x4" beam with 2"x6" weather treated lumber. I had to drill 4 holes through all three to insert 10" bolts. The tool enabled me to easily accomplish the objective.

Surprisingly good value

Would Recommend

Ten years ago I bought a similar drill. It was about the same price. That was surprising. It works well drilling through layers of pressure treated lumber.
