    Paddle Bits, Individual

    Paddle bits, also called spade bits, have a wide, flat blade. They are commonly used by tradesmen such as electricians and plumbers for drilling holes through studs in walls for running wiring or pipes (auger bits and hole saws are also used for this), but they also have a place in the woodshop for drilling on fine woodworking projects.
    An extension kit is available for the extreme jobs. It includes a 12″ extension shaft, and a bent-hex tool to securely tighten the retaining screws when the paddle bit is installed. (See image.)
