DeWALT DW5427B25 Drill Bit, 3/8 in Dia, 6 in OAL, Helix Flute, 2-Flute, SDS Plus Shank

SDS Plus two-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.
