Sonic's advanced flute design clears debris faster, keeping the cutting tip cooler and extending drill life. The industrial tungsten carbide cutting tip resists wear and breakage for maximum durability and the hardened nickel steel body withstands direct abuse. These drill bits have a fully ground, heat treated body to handle the shock and stress of cutting concrete, stone, tile, granite and other masonry materials and can be used in rotary or percussion drills.
