Power Pro Carbide-Tipped Drill Bits have a tip that ensures the precise drilling of pilot holes, making them ideal for masonry applications. The carbide material allows these bits to absorb heat more efficiently, thereby enabling them to run at higher speeds. Carbide-tipped drill bits are easy to use and highly effective in shallow holes. To effectively use Power Pro drill bits, a hammer drill is recommended. Do not use carbide tipped drill bits to drill plastic, wood, or metal, and always wear safety goggles.
