Vermont American. Redesigned with an aggressive screw tip, WoodEater drill bits work like auger bits. The self-feed screw tip helps draw the bit through wood. Ideal for remodelers, plumbers, and electricians, WoodEater drill bits require less effort to work with, and drill three times faster than standard spade bits, the maker says. Constructed of hardened carbon steel, the bits feature dual cutting spurs angled to score the hole on entry and exit for a cleaner hole and reduced blowout. WoodEater drill bits are available in nine diameters ranging from 1/2 inch to 11/2 inches. 800.742.3869.
