Rotary drilling. Positive angle tip geometry. Premium brazing material adheres carbide tip to the drill bit body for maximum durability. Slow spiral flute design ensures efficient material removal allowing the bit to run cooler and extending service life. Long sizes are 13in (330.2mm) versus 12in (304.8mm); allowing bit to fully clear a cinder block. Not recommended for drilling into glass and ceramics.
