We’ve all been there before: You’re pushing through a project, making good progress and picking up steam when you strip a screw or snap a bolt. Few things can bring your work to a standstill quite like this can. If you don’t have the right tools to remove the broken fastener, you’re really up the creek.
Fortunately, there are a few secret weapons you can make use of in these scenarios. You can start with the left handed drill bit. Today, we’ll take a closer look at this indispensable tool and show you some of the best left-handed drill bit sets on the market.
Let’s jump right into it, shall we? Here are our top five left-handed drill bit sets.
EAZYPOWER 82380 5-Piece Bit Set
If you’re looking for an affordable, no-frills bit set to help you extract broken fasteners, this 5-piece kit from EAZYPOWER is worth a closer look.
This bit set includes five common sizes, 1/8″, 3/16″, 1/4″, 5/16″, and 3/8″, which is a good assortment for drilling out smaller fasteners. These jobber sized bits contain M2 high-speed steel and have a 135-degree split-point. That means they’ll be able to drill into most fastener materials with little effort.
While this set is a solid option, it does lack the larger bit sizes. The larger bit sizes can be useful for drilling out larger fasteners. The bits also aren’t coated. This means there’s a chance you’ll run into a material that these bits just aren’t strong enough to drill into.
- Includes several popular sizes
- Bits aren’t coated
- Doesn’t include bits larger than ⅜”

Maybe I’m just a tool nerd, but I find left handed drill bits to be kind of fascinating. Here’s what makes these drill bits unique:
Left-handed drill bits, also called reverse drill bits are identical to the standard twist bits you’re used to seeing, with one key difference. Unlike a regular twist drill bit, which has flutes which twist up and around the bit in a clockwise direction, left-handed bits twist up in a counter-clockwise motion, which is opposite from traditional bits.
Left-handed bits are threaded in reverse, and when they’re used in a drill that’s in reverse, the bit will bite into the fastener as you drill into it. Since fasteners are also right-handed, once the bit bites into it, the torque from the drill should allow you to remove the broken bolt or screw and continue with your project.
One positive about shopping for drill bits compared to other tools; there’s a heck of a lot less to worry about. There’s nothing proprietary from company to company, and there aren’t too many features to concern yourself with. That said, you’ll want to keep a couple of points in mind to ensure the bits you’re buying will stand the test of time.
There are several different materials used to make drill bits. You’ll want to consider this carefully as certain bits are better suited for drilling into a particular substrate.
HSS bits are the most popular and inexpensive bits on the market. They’re made from steel, and they can make quick work of most materials, including wood, plastic, and softer metals. While these bits are perfectly suited for basic drilling, they don’t stand up to drilling into fasteners as well as other materials.
A step up from regular HSS, black oxide coated bits are more able to resist corrosion, and they’re more durable than uncoated HSS. This material is still less than ideal for drilling out fasteners, but it’s a step in the right direction.
When coated with titanium, HSS bits are substantially stronger, and they stay sharp longer than non-coated or black oxide coated bits. This material is a stronger choice for left-handed bits.
Is exceptionally strong, and it dissipates heat very quickly, making it a strong choice for drilling into extremely hard substrates, such as fasteners. Cobalt is an ideal material for left-handed drill bits, but it can also be expensive.
One of the newest and coolest materials for drill bits is niobium. These specialty bits have a coating of an extremely hard and durable metal which is designed to make quick work of drilling through difficult materials, like steel. These bits are becoming popular with metalworkers like locksmiths and gunsmiths, but the jury is still out on whether or not they’re better for extraction than cobalt.
The tip of the drill bit is an essential factor which helps dictate which type of work it’s best suited for.
With standard twist bits, there’s a variety of different tips available. Some are sharper, some are blunt, and some are specialty tips designed for boring into different materials.
With left-handed bits, there’s less to worry about. Bits with tips somewhere around a 135-degree angle are ideal for drilling into harder materials. They’re the most popular and useful style of tip when it comes to left-handed bits.
Each of the left-handed bit sets we’ve covered above is a solid choice to add to your toolbox. They’ll prove indispensable when the time comes where you need to remove a busted screw or bolt.
There can only be one winner, and our top pick as the best left-handed drill bit is the Irwin 35-piece kit. This kit includes everything you’ll ever need. Including a broad selection of different extractor bits. If this kit is more comprehensive than you need, you can save some money by opting for the Drill Hog 13-piece set. It is also an excellent choice.
