Screw Extractors

(Showing 9 of 9)

Screw extractors from Mechanidrive are designed to remove broken bolts, studs, socket screws and fittings. The utilize an aggressive left hand spiral flute for extra gripping power while piercing the extraction object. These spiral flutes are engineered to self-embed themselves deep into the metal object as the tool rotates. The basic physics of extractor screws increases resistance as it rotates faster and as its grip increases ultimately grasping enough of the object to simply remove it as its backed out of the material. They are identified by sizes # 1 through # 9 for specific drill cut diameters and their respective ID is etched onto the surface of each bit.
