3.1 Assess the Situation
Begin by evaluating the situation and determining the complexity of the broken drill bit piece. Take note of the depth to which the bit has penetrated the material. Such an assessment will help you choose the appropriate methods and tools for removal.

3.2 Gather the Necessary Tools
Before commencing the removal process, ensure you have all the required tools at your disposal. Proper preparation not only saves time but also helps you work with ease and precision. Put on your safety gear, including safety glasses, face shield, and gloves, to protect yourself throughout the process.

3.3 Breaking and Drilling Off
In some cases, the broken drill bit may be extending out of the surface. To remove it easily, use needle-nose pliers to break off any protruding parts. If the bit is fully embedded in the material, you will need to create a hole adjacent to it using a drill press or handheld drill. This hole will serve as a guide for subsequent drilling processes.

3.4 Extracting the Broken Drill Bit
To extract the remaining piece, select a carbide burr or end mill that matches the hole’s diameter and align it with the broken drill bit. Secure the piece in a vice grip to maintain stability. Apply gentle pressure and start drilling, ensuring not to exert excessive force to avoid damaging the surrounding material. Employ periodic lubrication to prevent overheating and enhance the drilling process.

3.5 Cleaning and Finishing
Once the broken drill bit fragment has been successfully removed, clean the area thoroughly. With a deburring tool or file, smooth any rough edges left behind from the process. Inspect the machinery and surrounding material for damage caused during removal. Address any issues immediately to maintain optimal performance and safety in future drilling endeavors.
