CRAFTSMAN 315 113861 Operator Manual

There are several possibilities. I am assuming that by "hang up" you mean that the motor still runs, but the arbor, chuck, and bit all stall. I also assume that you are running the bit up and down to clear out the wood shavings from the bit out of the hole, you are using the correct amount of downward force, and that the bit is sharp. I would first check to see that there is proper tension on the drive belt. You can add a belt spray designed to increase friction for better running. I would also gear down the drill press even more to increase torque (I know you say you are running at the correct speed, but try a reduced speed). Another method is to use an auger bit or a forstner bit without pilot holes. If you are using a spade bit, you might try no pilot hole, and drill at a faster speed. I have a junk 10" drill press and have no trouble drilling 1" holes in oak.
