Left-hand drill bits can be confusing if you are not familiar with them. Left-handed drill bits are designed for use in left-handed people. They are also called reverse helix drill bits.
To remove a broken fastener, use a center punch to mark the buckle. Using a left-hand drill bit and a drill in reverse gear, drill into the pin.
Drill it to a depth of 2/3 the length of the fastener. If you could not remove the pin previously, you can now use the hole to insert other extractors.
This article will show you how to use left-hand drill bits.

What are Left-Hand Drill Bits?
Left-hand drill bits are used to drill into materials that are not easily accessible with a right-hand drill. They are typically smaller in size and are used for preparing into small spaces, such as through wood or plastic.
Left-hand drill bits are specifically designed to drill left-handed screws, bolts, and other fasteners. They have a reversed-thread design that allows them to be used with a left-handed drill bit chuck. Left-hand drill bits are often slightly more significant than their right-hand counterparts, making them easier to handle.
Types of Left-Hand Drill Bits
There are three main types of left-hand drill bits:
1.The split point: The split point is the most common type of left-hand drill bit. It is designed for drilling in metal and has a split point that allows the bit to start drilling without needing a center punch.
2.The parabolic flute: The parabolic flute is designed for drilling in wood. It has a curved shape that helps remove chips and debris from the hole as you drill.
3.The black oxide: The black oxide is designed for drilling in plastic and other soft materials. It has a black oxide coating that helps to protect the bit. Left-hand drill bits come with a black oxide coating that helps to protect the bit. The coating prevents rust and corrosion, making the bit last longer.
How To Use Left Hand Drill Bits Step By Step
Step 1: Choose the Right Bit
There are many different types of left-hand drill bits, so it is essential to choose the right one for the job.
Left-hand drill bits are designed for drilling in left-handed orientations. If you’re not sure which left-hand drill bit to use, it’s essential to choose the right one for the job.
Left-hand drill bits come in various shapes and sizes, so it’s essential to find the one that will fit the hole you’re trying to drill.
Step 2: Pre-Drill a Hole
If you’re using a regular bit to drill a hole in something, it’s essential to pre-drill the hole first. This will make the bit go in more quickly and prevent the drill from getting stuck. You’ll need to use a left-hand drill bit to pre-drill a spot.
Step 3: Drill the Hole
When using a left-hand drill bit, it is essential not to apply too much pressure. If the bit is applied too much pressure, it may damage it.
Step 4: Clean Up the Hole
If you’re drilling a hole in a piece of wood and it’s not going very well, it might be time to clean up the hole with a file or sandpaper.
First, use the drill bit to make a small hole in the wood. Then, use the file or sandpaper to smooth out the hole until it’s almost perfect.
When Should You Use Left-Handed Drill Bits?
Left-handed drill bits are used when you need to drill in tight spaces or when your hands are too small. You can also use them on a right-handed drill by turning it Rather than rotating in the direction of the hands of a clock, rotating in the opposite direction.
Left-handed drill bits are most commonly used for drilling holes in wood, plastic, and metal. The bits spin clockwise, which means they will move the material to the left when drilling. This way, the material does not get stuck on the inside of the hole, and it is easier to remove it from the hole afterward.
You can use left-handed drill bits with any power tool or hand tool that accepts a standard size bit. They offer more control than right-handed drill bits as they push against your palm instead of your fingers.

How Should a Screw Extractor Be Used?
To use a screw extractor, first, follow the above steps. Assuming you were unable to extract the bolt, you will now use a screw extractor as follows:
- Insert the screw extractor into the drilled hole.
- Screw the extractor into the bolt.
- If the extractor doesn’t bite the bolt, try a larger one.
- Once the extractor has the bolt, slowly unscrew it.
When using a screw extractor, keep in mind not to break it inside the bolt. Metal screw extractors are challenging to drill out.
Use it manually instead of a slow drill to avoid breaking your extractor.
