Positive tip geometry for best rotary drilling efficiency. All sizes 3/16" and larger have 3 flats on the shank so that the drill chuck gets a better grip on the drill bit. Wide spiral flutes efficiently remove dust and debris, from the cutting area. Excellent for drilling high bulk materials such as damp masonry work, brick, cement, tile, slate and cinder block.
