Tools and Hardware Reviews of Irwin 30520 5 Piece Left Hand Cobalt 5/64-Inch to 19/64-Inch Cobalt Twist Drill Bit Assortment

Customer Review: must have
Summary: 5 Stars

Reverse drill bits are a must to have when extracting broken bolts. These drill bits come with the 11119 extractor/reverse drill bit set. You will break these, even though they're cobalt. It's nice to have spares on hand. 53535 is the extractor set, to have spare extractors.
