ชุดดอกถอนเกลียวซ้ายเยอรมัน HUNTER TUBUS Pipe Screw Extractor Set

Extractors have a tapered, spiral flute; use them to remove broken screws, bolts, studs, pipe, and other threaded parts. Simply drill a hole in the broken part, insert the extractor, and turn it with a standard wrench or a tap wrench, unless noted. The broken part will back out without damaging the threads.
