How to use left handed drill bits? Left-handed drill bits are a useful tool for anyone who needs to remove broken bolts or screws from a material. They offer several advantages over traditional drill bits, such as their ability to remove broken fasteners without causing further damage to the material.
However, using left-handed drill bits can be tricky if you are unfamiliar with them. In this outline, we will provide step-by-step instructions on using left-handed drill bits effectively. By following these guidelines, you can make the most of this useful tool and easily remove broken bolts and screws.
How to Use Left Left Handed Drill Bits – Gather the materials.
To use left-handed drill bits effectively, you will need the following materials:
- Left-handed drill bits in the appropriate sizes for the job
- A power drill or cordless drill
- Pliers or other tools for extracting the fastener once it starts to loosen
- Safety goggles or glasses to protect your eyes from debris while drilling
- Gloves to protect your hands from sharp edges or debris
- Lubricating oil, such as penetrating oil, to help loosen rusted or seized fasteners (optional)
Before starting, ensure that you have all the necessary materials and that they are in good condition. Inspect the drill bits and the drill for any signs of wear or damage, and replace them if necessary. Additionally, ensure that you are working in a well-ventilated area and have adequate lighting to see what you are doing.
Importance of using left-handed drill bits
Left-handed drill bits are important for several reasons:
- They offer a unique advantage in removing broken bolts and screws without causing further damage to the material. When used correctly, they can extract the broken fastener while also creating a hole that can be used for a new fastener.
- Left-handed drill bits can help prevent the need for more drastic measures, such as drilling out the entire bolt or screw, which can be time-consuming and costly.
- They can save you time and effort compared to other methods of bolt and screw removal, especially when dealing with rusted or seized fasteners.
- They are a valuable addition to any toolbox, whether you are a DIY enthusiast or a professional mechanic, as they provide a reliable way to deal with broken bolts and screws.
How to Use Left Handed Drill Bits – Step by Step Guide
Step 1: Choose the right drill bit size
Before starting, make sure to choose the correct size left-handed drill bit for the job.
You can determine the size by measuring the bolt or screw to be removed.
It’s essential to use the right size to avoid damaging the material or making the extraction process more difficult.
Step 2: Attach the drill bit to the drill
Insert the left-handed drill bit into the drill chuck and tighten it securely.
Ensure that the drill bit is centered and not wobbling.
Use the manufacturer’s instructions for attaching and tightening the bit.
Step 3: Set the drill to reverse mode
Set the drill to reverse or counterclockwise mode.
Left-handed drill bits are designed to rotate in the opposite direction of standard drill bits.
This counterclockwise rotation helps to grip and loosen the broken fastener.
Step 4: Align the drill bit with the broken or stripped fastener
Place the drill bit on the center of the broken or stripped fastener.
Hold the drill steady and perpendicular to the surface of the material.
Ensure that the drill bit is aligned correctly to avoid damaging the material or the drill bit.
Step 5: Apply pressure and begin drilling
Apply steady pressure and start drilling slowly.
Keep the drill perpendicular to the surface of the material.
Be careful not to apply too much pressure or force, as this can break the drill bit or damage the material.
Step 6: Stop drilling once the fastener starts to loosen
Continue drilling until the fastener starts to loosen.
This can happen suddenly, so be prepared to stop drilling as soon as it does.
If the fastener does not loosen after several attempts, stop drilling and try a different approach.
Step 7: Remove the fastener using pliers or other tools as necessary
Once the fastener starts to loosen, remove it using pliers, a screw extractor, or other appropriate tools.
If the fastener does not come out easily, try gently rocking it back and forth to loosen it further.
Be careful not to damage the material or the threads of the fastener.
In summary, using left-handed drill bits requires careful attention to detail and proper technique. By following these steps, you can effectively use left-handed drill bits to remove broken or stripped fasteners without causing further damage to the material.
FAQs
Can left-handed drill bits be used with a regular drill?
Yes, left-handed drill bits can be used with a regular drill or cordless drill. It’s important to make sure that the drill is set to reverse or counterclockwise mode before using left-handed drill bits.
What size left-handed drill bit do I need?
The size of the left-handed drill bit you need will depend on the size of the bolt or screw you are trying to remove. Measure the diameter of the fastener and choose a drill bit that is slightly smaller than the diameter to avoid damaging the threads.
How do I know if I’m using the right amount of pressure when drilling?
You should apply steady pressure when drilling, being careful not to use too much force. If the drill starts to bog down or the material starts to smoke, you may be using too much pressure. Ease up on the pressure and let the drill bit do the work.
Can left-handed drill bits be used on any material?
Left-handed drill bits can be used on a variety of materials, including metal, plastic, and wood. However, you should choose the appropriate type of drill bit for the material you are working with.
What should I do if the left-handed drill bit breaks during use?
If the drill bit breaks during use, stop drilling immediately and remove any remaining pieces of the drill bit from the material. Inspect the drill bit for signs of damage or wear, and replace it if necessary.
How do I extract the fastener once it starts to loosen?
Once the fastener starts to loosen, use pliers or other appropriate tools to remove it. If the fastener is still stuck, you can try gently rocking it back and forth to loosen it further.
Final Words
Using left-handed drill bits can be a game-changer when it comes to removing broken or stripped fasteners. By following a simple step-by-step process, you can easily remove even the most stubborn fasteners without causing damage to the material. Choosing the right drill bit size, attaching the drill bit to the drill, setting the drill to reverse mode, aligning the drill bit, applying pressure, and stopping once the fastener starts to loosen are all crucial steps in this process. With proper use and care, left-handed drill bits can be a valuable addition to any toolbox.
