Remove broken and damaged screws and bolts in two easy steps. Each of the four dualended
bits in this set feature a burnishing tip to prepare the screw or bolt for removal
and a threaded tip to grip and extract them when powered with a 3/8" drill. Removes
many types of screws up to 4" in length including hex, Phillips, torx and square drive
and bolts up to 3/8". Each of the four bits are different widths to handle a different
range of screw and bolt sizes.
