When grinding a twist drill bit, two main angles are created: the point angle and the lip clearance angle. The point angle is the angle formed at the tip of the drill bit and is typically around 118 degrees for general purpose drilling. The lip clearance angle is the angle formed between the cutting edge of the drill bit and the workpiece, which helps to prevent the drill bit from binding and overheating during drilling. These angles are crucial for ensuring the drill bit cuts efficiently and accurately. **

To remove a broken twist drill bit stuck in a drill, you can try using a pair of needle-nose pliers to grip the broken bit and gently twist it out.

Remember to wear safety goggles and work slowly and carefully to avoid damaging the drill or injuring yourself. **
