With our extensive selection of left-handed drill bits, you can be sure to find the right tool for the job.

Understanding Left-Handed Drill Bits

If you’re in the market for drill bits, you might have come across left-handed drill bits. Unlike conventional drill bits that rotate clockwise, left-handed drill bits rotate counterclockwise. In this section, we’ll take a closer look at the design, mechanics, materials, coatings, sizing, and types of left-handed drill bits.

Design and Mechanics

Left-handed drill bits are designed to rotate counterclockwise, which makes them ideal for drilling out broken bolts, screws, and studs. As the bit rotates, it tends to grip the broken fastener and turn it counterclockwise as well, loosening it from the surrounding material. Left-handed drill bits are available in both 135-degree split point and 118-degree conventional point designs.

Materials and Coatings

Left-handed drill bits are typically made from high-speed steel (HSS), which is a type of tool steel that can withstand high temperatures and maintain its hardness even at high speeds. Some left-handed drill bits also feature a titanium coating, which increases their hardness and extends their lifespan. Titanium nitride (TiN) coatings are also available, which provide even greater wear resistance and durability.

Sizing and Types

Left-handed drill bits come in a range of sizes and types to suit different drilling applications. Jobber length left-handed drill bits are the most common type and are suitable for general-purpose drilling. Aircraft extension left-handed drill bits are longer and are designed for drilling in hard-to-reach areas. Reduced shank left-handed drill bits have a smaller shank diameter than the cutting diameter, making them ideal for use in a drill press or other machine with a smaller chuck.

Practical Applications

Left-handed drill bits have a variety of practical applications. Here are two of the most common:

Removing Broken Bolts and Screws

One of the primary applications of left-handed drill bits is in the extraction of broken or stripped screws and bolts. When attempting to remove a stuck or seized fastener, using a left-handed drill bit can often save time and effort compared to other extraction methods. The counterclockwise rotation of the left-handed drill bit combined with the drilling action helps to loosen and extract the stuck or broken piece without causing additional damage.

To use a left-handed drill bit for this purpose, drill a small pilot hole in the center of the broken bolt or screw. Then, insert the left-handed drill bit into the pilot hole and begin drilling in reverse. As the drill bit turns counterclockwise, it will begin to grip the bolt or screw and loosen it from the threads. If the bolt or screw is not completely removed, use a screw or bolt extractor to finish the job.

Reversible Drill Compatibility

Another practical application of left-handed drill bits is their compatibility with reversible drills. Reversible drills have a switch that allows the user to change the direction of the drill bit’s rotation. This feature is particularly useful when using left-handed drill bits because it allows the user to drill in reverse, which is necessary for removing broken bolts and screws.

To use a left-handed drill bit with a reversible drill, first, ensure that the drill is set to reverse. Then, insert the left-handed drill bit into the chuck and tighten it securely. Begin drilling in reverse, and the drill bit will begin to grip the bolt or screw and loosen it from the threads.

Selecting the Right Drill Bit Set

When it comes to selecting the right drill bit set, there are a few factors to consider. Whether you’re a DIY enthusiast or a professional, having the right set of drill bits is essential for any job. Here are some things to keep in mind when selecting a left-hand drill bit set.

Factors to Consider

  1. Material: Consider the material you’ll be drilling into. Different materials require different types of drill bits. For example, if you’re drilling into metal, you’ll need a set of drill bits that are designed for metal.
  2. Size: Make sure to choose a set of drill bits that includes the sizes you need. It’s better to have a set with a variety of sizes so you can tackle any job that comes your way.
  3. Quality: Look for a set of drill bits that are made from high-quality materials. A set that is made from high-speed steel or cobalt will last longer and perform better than a set made from lower-quality materials.
  4. Price: Consider your budget when selecting a drill bit set. While it’s important to invest in a high-quality set, you don’t want to overspend.

Top Brands and Products

When it comes to left-hand drill bit sets, there are a few top brands and products to consider. One of the best options is the Drill Hog 13 Pc Niobium Left Hand Drill Bit Set. This set is made from high-speed steel and features a unique niobium coating that makes the bits last longer and perform better.

In conclusion, selecting the right drill bit set is essential for any job. Consider the material, size, quality, and price when making your selection.

Usage and Maintenance Tips

Proper Technique for Efficacy

When using left-handed drill bits, it is important to follow proper technique for maximum efficacy. First, ensure that you have selected the correct bit size for the hole you wish to drill. Then, set up your drill to reverse mode and position the drill bit at the center of the screw or bolt you want to remove. Apply gentle pressure and start drilling slowly to avoid slipping. The left-handed bit will attempt to grip and turn the screw or bolt in reverse.

It is important to monitor the drilling process closely. If the bit fails to loosen the bolt, you may need to use vise grip pliers to extract it. In some cases, the left-handed drill bit may fail to loosen the bolt, but it is still a useful tool to have in your toolkit.

Caring for Your Drill Bits

To ensure your left-handed drill bits last as long as possible, it is important to take proper care of them. After each use, clean the bit thoroughly to remove any debris or metal shavings. This will help prevent damage to the bit and ensure it remains sharp for future use.

It is also important to store your drill bits properly. Keep them in a dry, cool place to prevent rust and other damage. Additionally, be sure to use the proper torque and angle when drilling to prevent damage to the bit and ensure maximum efficacy.

Purchasing and Customer Service

Where to Buy
