About This Item: The ThunderBit® series from Triumph has been one of our best selling high-speeds for over twenty years. It’s arguably our best all-around drill bit and now with the new 3-flat shanks, slippage is a thing of the past. It cuts ferrous and non-ferrous metals as well as wood. Use it in a drill press or out in the field. You’ll enjoy an 8:1 holes-drilled ratio compared to standard general purpose drill bits and the tapered flute means the bit thickens near the shank, preventing snapping. Go nuts!
