Drill bit geometry has several characteristics: The spiral (or rate of twist) in the drill bit controls the rate of chip removal. A fast spiral (high twist rate or "compact flute") drill bit is used in high feed rate applications under low spindle speeds, where removal of a large volume of chips is required.
These tungsten carbide tipped bits are used on hammer drills (on hammer mode) for drilling into bricks, concrete, and stone. Some professional quality masonry drill bits will also feature a hexagonal shank (instead of a cylindrical shank) to stop the bits from slipping in the chuck when the drill is experiencing substantial loads, and also a percussion ground carbide tip.
