These bits used to last a while. Now they don't even cut a hole. I used a 1-3/8" drill bit and before the hole was cut the drill bit broke off. Someone at the factory didn't tighten the set screw properly and it rounded the drill bit. Now the hole saw just spins on the bit .A complete waste of money.
