    With Ball Detent

    Flip these bits around for a fresh tip or to drive a different size Phillips screw. Phillips bits align easily with fasteners and deliver more torque than slotted bits.
    Also known as insert bits, these snap into hand drivers.
    Steel—Best for dry environments, since moisture will cause these bits to rust.
    Ball-Detent Bit Holder—Bits with a ball detent are less likely to slip out of the holder than ones without. However, they don't slide in and out of the holder as easily.

    Drill, countersink, and drive screws without switching three separate bits in and out of your power tool. With a single hand, flip between drilling countersunk holes and driving screws. The countersinking drill and screwdriver bit are secured with set screws, so you can switch them out for any bits with a 1/4” hex shank.
    The countersinking drill has an 82° angle, allowing inch-sized flat- and oval-head screws to sit flush with the surface.
