I bought this magnetic drill specifically for the chuck adapter with a regular wrench. With a hand drill I'd be just as stable and probably do less damage. The racquet wobbled and hooked instantly, snapping off two cutting edges and one of which flew into the air, causing more wobble and imbalance before I could knock it out. The damaged bat was unused and cost about $120. The damage to work is about a few hundred dollars if I fix it myself not counting the work. For a brand name drill bit costing almost $800 you would think it could drill a hole and drill right through. I was wrong. Taking a 4,000-pound piece of steel to the machine shop would have been less hassle and money after the damage the drill did. And now I have to take it to a UPS store 30 miles away to get it back.
