Damaged Screw Extractor Kit, 22 Pieces Broken Bolt Stripped Extractor, HSS Magnetic Extension Bit Bolt Remover Set with 10 Sizes Drills and Extractor for Broken Screw, Bolt Stripped Remover

waste of money even after taking every possible preparation step ready to extract the bolt the bits would break, either gentle or giving some impact

Having drilled out the hole and put the extractor bit in, applying a bit of turning force on it caused the bit itself to shear off, leaving itself now filling the hole ID just drilled. So now i have a screw and an extractor bit to try and remove.Pretty shoddy.

Used the first bit too thread the screw, as instructed. When using the 2nd, as instructed, it almost immediately snapped.
