5pc IMPACT SCREW EXTRACTOR SET
This Kincrome Impact Driver Bit set contains 5 high-quality 80mm extractor impact bits and are designed for use with 5/16" drive manual impact drivers.
They have a reverse-spiral pattern which is designed to bite into rounded fasteners and allow the manual impact driver to successfully remove them.
Note - you may need to drill out the fastener for the extractor to fit and work correctly.
