PROBLEM TO BE SOLVED: To easily remove a bit cut into a workpiece. SOLUTION: In an impact tool attachment 1, a front attachment portion 3 to which other bit is insertedly attached is disposed at a front section of a body shaft 2, and a rear attachment portion 4 attachable to an anvil of an impact wrench is disposed at a rear section of the body shaft 2. The front attachment portion 3 has the same structure as an attachment portion of a bit disposed at the front end of an electric hammer or a hammer drill, and the rear end of a bit inserted into an insertion hole 8 is connectable by a ball and a projection 11. Similarly to the rear end of a socket attached to the anvil of the impact wrench, the rear attachment portion 4 includes an anti-disconnect mechanism comprised of a through-hole 15, a pin 16, a recessed groove 17, and an O-ring 18.
