The 13″ Rotary Masonry Drill Bit with Reduced Shank is for rotary drilling in brick, stone, damp and dry masonry and concrete. Premium brazing material adheres the carbide tip to the drill bit for maximum durability. The slow spiral flute design ensures efficient material removal allowing the bit to run cooler and extending its service life. Its 13″ (330 mm) length, versus 12″ (305 mm), allows the bit to clear a concrete block. 3/8″ (9.52 mm) reduced shank allows the bit to be used in most drills.
