The high-volume, double-helix design of the quad-head bit comes with the patented, high-performance, reinforced core flute to maximize energy transfer. 4 x 90° head geometry crushes through rebar and prevents sticking in reinforced concreteĪll the features of single cutter bits and the quad-head dual-cutter are designed to improve durability and drilling speed. What is an SDS-Plus Drill Bit SDS bits with grooved shank and tiny carbide blades in the tip to smash stones.Patented, high-volume, multi-flute spiral quickly channels concrete dust from the hole to improve drilling speed.Seamlessly use Tapcon Drill Bits with Tapcon anchors to ensure drilling precise holes and achieve. The SDS eliminates slippage, providing for productive, high-torque drilling in Concrete and masonry. Chisel-shaped drill-bit head penetrates the material and directs concrete dust into the multi-flute spiral Engineered for heavy-duty use in rotary hammers, the Tapcon SDS carbide drill bit easily drives through Concrete and masonry.Drill bits conform to ANSI Standard B212.15Īdditional Features for select SDS-plus bits:.Heat-treatment procedures and shot-peened finish increase surface hardness, drilling speed, reduces drill bit wear and improves resistance to bending forces.Chromium-nickel-molybdenum steel alloy body ensures hammering quality and extended service life Sabre Tools 4-Piece 12in SDS Plus Drill Bit Set, Carbide Tipped, Rotary Hammer Drill Bits for Brick, Stone, Concrete (1/4 x 12, 5/16 x 12, 3/8 x 12, 1/2.Most bits contain a centering tip that facilitates easy spot drilling. Uniformly brazed carbide inserts result in longer bit life.
