Screw Extractor & Cobalt Left Hand Drill Set

Description

Break a bolt? Back it out fast.

This 10-piece set includes 5 left-handed cobalt drill bits and 5 multi-fluted alloy steel screw extractors, giving you the tools to remove broken bolts, studs, and screws cleanly—without damaging threads.

The reverse-flute cobalt drill bits bite hard in reverse. Most of the time, just chuck the bit, run the drill in reverse, and the broken fastener walks out on its own. No extractor needed.

When you do need an extractor, this set has 5 precision-machined multi-flute extractors that drive deep and lock in. Just drill the hole (correct bit size is marked inside the steel case), insert the extractor, and turn it out with a tap wrench. The spiral design grips like a corkscrew and backs the broken fastener out fast.
