Drilling through stainless steel can be challenging, and it’s not uncommon for drill bits to break during the process. Some common causes of drill bits breaking in stainless steel include:
- Using the wrong type of drill bit
- Using a dull or worn-out drill bit
- Exerting excessive pressure or force while drilling.
- Drilling at too high of a speed
- Not using enough lubrication during the drilling process
- Using a drill bit that is either too small or too large for the task.
Understanding what causes drill bits to break in stainless steel can help you avoid this problem in the future and ensure a successful project.
To remove a broken drill bit from stainless steel, you’ll need the following tools:
- Safety goggles
- Leather gloves
- Needle-nose pliers
- Left-handed drill bit
- Lubricant (such as oil or WD-40)
- Centre punch

Before removing the broken drill bit, taking the necessary safety precautions is essential. Ensure you wear your safety goggles and leather gloves, and remove any loose clothing or jewellery that could get caught in the drill.
Next, clean the area around the broken drill bit with a cloth and alcohol. This will remove any dirt or debris that could interfere with the process.
It’s also essential to identify the type of stainless steel you’re working with, as this can affect the method you use to remove the broken drill bit. Austenitic stainless steel, for example, is more challenging to drill through and may require a more specialized approach.
Take note of the type of stainless steel you’re working with before proceeding with the removal process.
Several steps can be used to remove a broken drill bit from stainless steel.
The first step in removing a broken drill bit from stainless steel is to identify the location of the broken bit. Use a flashlight or magnifying glass to locate the broken piece.
Once you’ve identified the broken drill bit, secure the stainless steel piece in a vice or clamp to keep it from moving during removal.
Apply lubricant (such as WD-40) to the broken drill bit. This will help lubricate the area around the bit and reduce friction during removal.
Using a drill bit of the same size as the broken bit, drill a hole directly into the centre of the broken bit. Apply moderate pressure and slow speed to avoid overheating and breaking the new bit.
Once the hole has been drilled into the broken bit, use an extractor or pliers to remove the broken piece carefully. If the fractured bit is stuck, tap it gently with a hammer to loosen it, and then try to remove it again.
If the broken drill bit cannot be removed using the above steps, you can try a few alternative methods.
If the previous methods fail or if you prefer to use alternative methods, there are a few other options to consider.
Welding is a technique to fuse metal parts together by melting the base metal and adding filler material. In the case of a broken drill bit, welding can melt the surrounding metal and fuse the fractured piece to a new drill bit. This method requires advanced welding skills and specialized equipment.
A Dremel is a handheld rotary tool that can be used for various tasks, including removing a broken drill bit.
The process involves using a cutting wheel or a grinding bit to carefully cut away the surrounding metal and expose the broken bit. Once exposed, the bit can be removed using pliers or another suitable tool.
A centre punch is a tool used to create a slight indentation or hole in a piece of metal. It can also be used to remove a broken drill bit.
The process involves using the centre punch to create a small hole in the center of the broken bit. This will create a space for the bit to move around, making removing it easier.
Sometimes, a hammer and chisel can remove a broken drill bit. This method involves carefully chiselling away at the surrounding metal until the fractured bit is exposed. Once exposed, the bit canved using pliers or another suitable tool.
It’s important to note that these alternative methods may not be as effective or safe as the previously mentioned methods, so use caution and proceed with care.
