The Malco Tools Screw Extractor Kit offers left-handed cobalt drill bits and straight-fluted extractors to make screw and bolt extraction faster, easier and safer, according to the company. Left-handed cobalt drill bits create a pilot hole for the extractor and also loosen, or even remove, corroded, stripped-out, or headless threaded fasteners with the momentum of the left-turning bit. Straight-fluted extractors with a hollow-ground, hardened edge provide extra bite in the pilot hole and can be torqued in either direction to loosen a frozen screw or bolt. For use with screw or bolt diameters of 1/4" to 5/8", this 10-pc kit contains five straight-fluted, alloy steel extractors and five matched left-handed cobalt drill bits.
