Purchased for drilling wood and 3/16 inch rolled steel - drill bits punched through steel - 2 broke after drilling a few holes and 1 broke due to the increased pressure to purchase Equivalent DeWalt Brand Type - 50% less force required to pierce metal, no broken/broken bits and time-saving bits It's always tempting to think we're paying for the name, especially when the packaging and images are designed the way you do need unless you want a cheap all-wood set and don't mind losing a few sizes if they smash/break under pressure.
