2 cutter drill bits have a strong tapered core to help resist flute breaks, especially when drilling deep holes. For optimal drilling speeds, the two stage flute design features a variable helix pattern that quickly moves debris away from the contact zone. Plus, the two sharp, carbide cutting edges deliver clean, round holes for secure anchor installation. These bits are made in Germany and are GUARANTEED TOUGH® - so tough that we are offering a NO BREAK GUARANTEE. If you have our bits, we have your back.
