Left hand drill bits can be a game changer for anyone who works with metal or deals with broken bolts. They turn in the opposite direction from regular bits, making them perfect for removing stubborn screws and fasteners. The best left hand drill bits make these tricky jobs much easier and help avoid further damage.
If you often find yourself fixing or rebuilding things, having a reliable set is a smart move. Choosing quality bits means you get cleaner holes, less frustration, and more time saved in the workshop. Here’s what sets the top options apart and why they matter for your next project.
Valyriantool Cobalt Left Hand Drill Set
For those searching for the Best Left Hand Drill Bits, this set works well for DIYers and mechanics who need to remove broken bolts and screws cleanly.
This set is a group of left hand drill bits made from M35 cobalt steel. It is designed to help you back out broken screws and bolts without damaging the workpiece. The range of sizes means you can match the bit to the job, and the self-centering tip helps keep drilling straight.
In practice, the bits grip well and start easily, even on tough metals like stainless steel. Swapping sizes is simple thanks to the clear markings on the case. There is less slipping and the process feels steady, saving time and reducing frustration.
Everyday Use: What To Expect
- Plastic case keeps bits sorted and easy to find
- Works well on common metals found in household repairs
- Bit tips stay sharp through repeated use
- Removes broken bolts without extra tools
- Some bits are thin and need a gentle hand to avoid snapping
- Imperial sizes only—no metric included
Steady Results For Tough Jobs
This set is best for anyone who often works with metal or needs to remove broken fasteners during repairs. It is a good choice if you want to avoid using extractors and prefer a single step. The included case helps keep everything organized, so you do not waste time searching for the right size.
If you only drill wood or plastics, or need metric sizes, you will want to skip this. The thinner bits do require careful handling, especially on hardened materials, to avoid breakage. A practical tip: start slow and let the bit do the work to avoid snapping.
The cobalt steel build offers confidence that these will last with regular use. Even if you are new to left hand bits, the clear markings and reliable grip make it an easy set to use without stress.
Valyriantool Left Hand Drill Bit Set
The Best Left Hand Drill Bits for anyone needing a reliable way to remove broken bolts or screws in tight spaces.
This set includes five left hand drill bits designed for removing broken bolts, screws, and stubs. The reverse twist helps loosen stuck fasteners while drilling, reducing frustration compared to standard bits. The stubby design allows you to reach into tight or awkward places where longer bits would not fit.
In practice, the bits feel solid and precise. The self-centering tip means you spend less time trying to keep the bit steady. It makes tricky jobs more manageable, even if you have little experience with extraction work.
Everyday Use: What Stands Out
- Quickly backs out left-threaded bolts and screws.
- Works well on hardened metals like steel and cast iron.
- Short length fits easily into tight engine bays or corners.
- Easy to identify each size in the storage box.

When These Bits Make Sense
If you regularly deal with stubborn, broken fasteners or work on cars and machinery, this set fits well. The bits are also practical for anyone who needs a compact drill bit that can handle tough metals without slipping.
Those who rarely encounter seized screws or only work with soft wood might find the specialty design unnecessary. The short length may not be ideal if you need to drill deep holes.
- Best for: Mechanics, DIYers, metalworkers
- Not for: Deep drilling, basic household jobs
Solid Pick For Tough Removals
This set is a steady choice for people who often struggle with broken bolts or screws, especially in cramped spots. If you value having the right tool for metal extractions, it fits the bill. Beginners should take their time with the self-centering tips; a steady hand helps.
For those who only need standard drilling or rarely run into seized hardware, a regular bit set is simpler. But if you need reliable left hand drill bits that last, this set is likely to meet your needs. The storage box keeps things organized, so you can grab the right size when it counts.
If you’re unsure, try the smallest size first on a scrap piece to get a feel for the reverse action. Most users will find these bits trustworthy for their intended purpose.

If you plan to use these for standard drilling, you should look elsewhere. These are specialized for extraction tasks. Keep the case handy—having the full set organized makes jobs smoother and less stressful.
How To Choose The Right Left Hand Drill Bit Set For Your Needs
Start by thinking about what you’ll be drilling into most often. If you only need to remove broken bolts now and then, a smaller set can be enough. For frequent repairs or different metals, consider a full range of sizes. Notice the bit material—cobalt and niobium each have strengths. Check if the set includes a storage case for easy organization. Shorter “stubby” bits are helpful in tight spots. Most people miss this: left hand bits work best with reversible drills and slow speeds.
The 30-second Checklist For Left Hand Drill Bit Buyers
- Will you be drilling into hard metals like stainless or cast iron?
- Do you need to extract broken screws or bolts?
- Is your drill reversible?
- Do you have enough space for full-length bits, or need stubby ones?
- Do you prefer bits stored in a labeled case?
- Will you use these often, or just for emergencies?
Common Regrets And How To Avoid Them
Regret #1: Choosing the wrong size set. Some users buy large sets but only use a few sizes. Fix: Match your set size to your most common tasks.
Regret #2: Using the wrong drill speed or direction. Left hand bits need to turn counterclockwise at low speed. Fix: Always double-check your drill’s settings before starting.
Regret #3: Expecting one set to last forever. Hard metals and heavy use will wear bits down. Fix: Replace individual bits as needed and store them carefully to extend their life.
