Each step of the bit has a different diameter, allowing the user to drill multiple sizes of holes with just one tool. **Q: What is the difference between a step drill bit and a regular drill bit?** A: A regular drill bit has a fixed diameter and can only drill holes of that size, while a step drill bit has multiple steps with increasing diameters, allowing it to drill multiple sizes of holes with one tool. **Q: What is the proper way to use a step drill bit?** A: The proper way to use a step drill bit is to start with the smallest step and gradually work your way up to the desired hole size. It is important to use the correct speed and pressure when drilling to avoid overheating the bit. **Q: Can step drill bits be used with a hand drill or only with a drill press?** A: KSEIBI Step drill bits can be used with both a hand drill and a drill press or even the impact screwdriver. However, using a drill press can provide greater control and precision when drilling, particularly with thicker materials. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect *by M***D on 16 March 2024* Worked exactly as advertised.
