IMPORTANT: We do not recommend using a corded heavy duty drill with these hole cutters nor are they needed. With no sidewall friction to overcome even the largest diameter hole cutters can be used with a cordless drill. These new highly efficient hole cutters require a different approach to maximize their life. They should be used with a 18v cordless drill with the screw setting when available. It will not slow down the cutting operation. With a 3-speed range cordless drill the middle setting works the best for all sizes.
