29pc Left-Hand Spiral Performance Series

Built for broken hardware.

The Ultimate 29pc Left Hand Drill Bit Set is purpose-built for drilling and removing snapped bolts, seized fasteners, and work-hardened studs. Left-hand rotation applies reverse torque while cutting, allowing fasteners to back out during drilling instead of driving themselves tighter. In many cases, extraction happens before a screw extractor is even needed.

Each bit is ground from premium high-speed steel with precision-controlled points, flutes, and body clearance to maintain accuracy, stability, and cutting efficiency under load. The black and gold finish reduces friction and heat, extending tool life in demanding metalworking and repair environments.

Sizes range from 1/16″ through 1/2″ in 1/32″ increments, giving you full coverage without gaps. Whether you’re drilling pilot holes, backing out broken bolts, or prepping for extraction, this set keeps you moving.

The bits are stored in a waterproof, heavy-duty polymer case built to survive jobsite abuse, service trucks, and toolboxes without cracking or warping.

This is not a disposable import set.
This is a professional left hand drill bit solution—made in the USA and built for repeat use.
