The 10-piece Stripped Screw Extractor Set, 61980, from Lisle Corp. features 10 sizes of extractors that fit Torx and Torx Plus sizes T-10 to T-55; internal hex sizes 7/64″ to 3/8″ and 3mm to 10mm.
They will also work on other internal drive screw heads. The six-lobed spiral bits are designed to remove rounded or stripped fasteners with internal drive heads.
Instructions:
To remove broken bolts, drill a pilot hole for the appropriate size extractor. Choose the extractor that fits snugly in the fastener. Turn counter-clockwise to remove the fastener. It may be necessary in some applications to drive the extractor into the fastener with a hammer for maximum torque.
