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!
For over 60 years Triumph Twist Drill has been manufacturing hundreds of thousands of drills a week. At our 70,000 square foot facility located in Chisholm, MN, we incorporate cutting edge machinery and equipment to produce exceptional performance tools.
Flat $15 shipping until then.
