Bought to replace a cheap ACE bit set I bought over 10 years ago. Wanted more choices than the 8-bit ACE in a set that fits on a tool belt. I've been using my ACE bits on a project all morning and remembered my new "Titan" bits. Got the exact same bit as the one I've been using for the past two hours. I went about 1/2 way up the tree and the bat broke in half. I put the ACE bit back in and drilled for another hour with no problems. Walked in and immediately requested a refund for this item. Maybe if you live in an apartment, is it bearable?
