Drilled about 50 holes in 2 large cherry tree stumps and still ready for more. My only complaint, which only gives it 4 stars, is that the drill bit wasn't perfectly straight, which could cause the drill bit to wobble when the drill bit was about 2/3 of the way through. Working slowly keeps the drill relatively cool and sharp. , and the oscillation is controlled. Note: You need a good 1/2" drill bit to drill a lot of holes in stumps: batteries only punch a few holes and I burned a cheaper 1/2" plug. - Drill less than 10 holes. Cheap under $50, at least $100, often on sale in the $80 region. The drill will get hot and if it gets too hot, let it cool down to avoid burning the drill.
