Estate sale. Used 1/2" drill. Works great. Not convinced that the hammer feature is working, but you may have different results (or may be able to repair, if indeed broken). Powerful. This drill will take your arm right off, if you're not careful. $200 + taxes on Amazon https://www.dewalt.com/products/power-tools/drills/drills-and-hammer-drills/12-single-speed-hammer-drill/dwe5010 $75
