Needed to get at at a 4" PVC pipe buried under 8" of very old concrete. This drill went through it fine, tried to wrench out of my hands a few times but the clutch cut it off. This is just a fantastic tool. My main heartburn (as with some other reviewers) was the water fitting. No, HD did not have it and after quite a bit of searching, Lowe's did. That said, I had to buy a $20 kit to get the fitting I needed. Anyway, once fitted the whole thing worked great. Wish I had started the project with this.
