If you frequently deal with stuck bolts, this set could be your go-to solution for hassle-free extractions.


  • Simplifies removal of broken fasteners
  • High surface hardness aids in penetrating tough materials
  • Left-hand design pairs well with screw extractors


  • Struggles with extremely hard materials like cast iron

The titanium nitride coating also appears to hold up well, giving these bits a tough exterior that withstands much of what we throw at them. However, we did notice that there may be better matches for denser materials like cast iron, which is worth considering depending on the task.

Adding to the practicality is the well-thought-out metal index case.

  • There may be a learning curve for those new to left-threaded bits

Having had our fair share of encounters with immovable bolts and screws, we've come to appreciate the reliable performance of Drill Hog's set. The resilience of the HI-Molybdenum M7 steel became clear after repeated use, showing no signs of wear or damage.

Drill Hog Lefty Bit Set

Drill Hog Left Handed Drill Bits

We recommend this set for anyone looking to remove broken bolts efficiently with durable drill bits.


  • Removes broken right-hand bolts effectively
  • High heat resistance increases longevity
  • No need for a pilot hole simplifies the process


  • Limited to only five sizes
  • May not be suitable for all materials
  • Higher price point than standard bits

Having recently had the opportunity to use these left-handed Drill Hog bits, they truly deliver on their promise. Their construction from Niobium Nb41 steel suggested impressive durability and lived up to that expectation during use. We effortlessly removed several broken studs from a tractor, and these bits bit into the metal without a hitch, negating the need for any pilot holes.

We were initially skeptical about not needing a starter bit, but these bits' performance could have been better. We didn't need extra steps to extract stuck bolts; we just set our drill in reverse, as instructed, and the bits grabbed and twisted out the stubborn bolts like a charm. This feature saved us significant time and hassle, especially when working with troublesome farm equipment.

Their heat-resistant quality also stood out. Despite the friction and heat generated from the removal process, the bits maintained their edge and showed no sign of premature wear. However, It's essential to mention that while the set includes a proper range of sizes from 1/8" to 3/8", this may not cover every potential task, especially if you're dealing with various bolt sizes. Also, their heavy-duty nature comes at a higher cost than more common drill bits, which might be a consideration for those on a strict budget. Despite the price, the durability and the lifetime warranty offer peace of mind and justify the investment.
