Self-feed bits that bog down, hop, and burn through wet treated lumber cost you time and ruined stock - the bit chatters as it grabs, the feed rate falls behind the cut, and the smell tells you the edge is gone before the hole is done.The 1-1/2-inch diameter with a forged bore head cuts faster than a standard spade bit and holds its edge through damp or dense lumber where other bits stall. The large chip-pull flight clears sawdust continuously so heat doesn't build up and cook the tip. 1/2-inch hex shank fits standard drill chucks and most portable drill drives - no special tool required.Standard on framing crews and rough carpenter bit kits across northeast Nebraska and northwest Iowa - the bit that keeps cutting when the lumber is green or wet from spring rain.In stock at Crofton Lumber Stocked at Crofton Lumber and Akron Lumber.
