Normally, a big old 1/2-inch drill motor would be the weapon of choice for turning a 4-inch hole saw (the only tool you may not have handy, but it's not essential, either-it just makes a neater hole). As it turned out, a cordless drill motor set on a relatively high torque setting (not the drill setting) made the holesaw stop when it inevitably grabbed every now and then, rather than flinging us out of the bed.
