Outstanding lifespan in concrete! High-quality, tough tungsten carbide ensures strength and durability. To drill large through holes in concrete, a suitable drill bit must be chosen. A drill bit with a cutting tip strong enough to penetrate the material and a shank that efficiently removes concrete particles and dust. The PRO SDS max Break Through drill bit is the ideal solution, as it allows you to drill large through holes, time and time again. The PRO SDS max Break Through punches into the material with its 3-cutter tip. It is made from high-quality carbide that has been vacuum soldered and hardened for stability and longevity. The U-shape of the drill bit, along with the two spiral flutes and the tapered shank, prevents dust and concrete particles from clogging it. Drill holes with a diameter of 45 to 80 mm.
