You might be thinking about these questions: Why do we need the finest left-hand drill bits? What are they good for? Well, here’s the answer. Most bits turn clockwise towards the right. However, left-handed bits turn counterclockwise to the left. These bits were created back in the days when power drills did not have reverse functions. It was much easier to use a left-handed tool than to manually reverse it.
Left-handed bits can still be used to remove bolts and other fasteners from holes that have become damaged. You can usually loosen the broken screw by drilling into it with a left-handed bit.
We’ve collected some left hand drill bits to save you time when doing repairs or installing something. These special bits can be constructed from different materials such as high speed steel and come in different sizes, depending on what you need.

Buyer’s Guide for The Best Left Hand Drill Bits
Fortunately, you have a lot fewer things to worry about when you are shopping for drill bit than other tools. There aren’t many things to worry about, and nothing is proprietary between companies. To ensure that the pieces you buy will last, there are a few things you should keep in mind.
Materials of Drill Bits
Different pairs of drill bits can be made from many different materials. This is something you should consider as some bits are better suited to drilling into particular substrates.
High-speed steel bits are some of the most common and affordable bits on the market. These bits are made of steel and can quickly cut through most materials, including wood, plastic, and softer metals. These bits can be used for basic drilling, but they are not strong enough to drill into fasteners or other materials.
Black Oxide Coated HSS
Black oxide-coated bits offer a step up to regular HSS and are more resistant to corrosion than uncoated HSS. Although this material is not ideal for drilling fasteners, it’s a good step in the right direction.
HSS Titanium Coated
HSS bits can be coated with titanium to make them stronger and last longer than black oxide or non-coated bits. This material is an excellent choice for left-handed bits.
Cobalt is extremely strong and dissipates heat quickly. This makes it an attractive choice for drilling into very hard substrates like fasteners. Cobalt can be used to make the drill bit, but it can be costly.
Most of the left-hand drill sets we have listed here have sizes between 1/16 and 1/2 inches. You can also find smaller kits with sizes as small as 1/4-inch. It’s up to your needs and what you use for your projects. For those who are only looking to do a few minor repairs, the smaller kits of 5-piece and 13-piece may be more appropriate than the larger 29-piece versions. This is because they’re better suited for people working on large-scale industrial projects.
These left-hand drill bit picks have a split-tip or some design that helps to reduce chipping. This could be useful for working with wood or other materials that might make a mess. Some bit-end designs allow for easy penetration.
A case that organizes the bits correctly would be helpful. Although stackable containers can make the container smaller, they are more difficult to grasp and move than single-layer ones.
Metal drill bit cases are more durable than plastic ones, and there’s less chance of them breaking or cracking. For easy identification, labels with the sizes written in bold fonts (or black) are a good idea. However, it is possible to read sizes of drill bits easily if they are engraved, as engravings are not erased.
How to Use Left-hand Drill Bits for Removing Broken Bolts?
Although it is difficult to remove a bolt or screw that broke, certain tools can be helpful. The finest tool is left-handed drill bits. This bit should be used in a drill with the reverse gear.
A right-handed drill bit can be helpful to drill out the broken bolt if it is not going through the material. You can use a left-handed drill if the hole isn’t visible.
Left-handed drill bits can be used in the opposite direction to normal bits. If the drill bit bites into the material, there is a possibility that the drill will pull out the damaged portion.
Start by making sure the bolt is flat. If it isn’t, you must file or grind it.
Next, carefully drill the center punch of the bolt with a center drill.
You can now insert the left-hand drill into the chuck and drill the hole in reverse.
The reversible drill bit will remove the screw from the hole if it bites. You can also use an easy-out or screw extractor if the bolt is not removed.
The tip of the drill bits is an important factor that determines which type of work it’s most suited to. This is the part of the drill bits that come in contact with the surface of a metal or wood.
There are many tips to choose from when using standard twist bits. Some tips are available, including some that are sharper than others, some less blunt, and some specially designed to bore into different materials. If you want precision, choose a sharp tip.
Left-handed bits are easier to use and less stressful. For drilling into harder materials, bits with tips at a 135-degree angle are ideal. These are the most useful and popular tips for left-handed bits.
Each of these left-handed bit sets is a great addition to your toolbox along with cutting tools. These bits will come in handy when you have to remove a broken bolt or screws.
