Application
Functions For Center Drill:
1. Multi-size Drilling: One step drill can create holes of multiple diameters, reducing the need to frequently change drill bits.
2. Efficient Processing: The unique stepped design enables quick and burr-free drilling, enhancing work efficiency.
3. Precision Positioning: The stepped structure helps with precise positioning and stable drilling, reducing hole diameter errors.
4. Versatility: Suitable for electrical installations, metal processing, DIY projects, and more, especially effective for drilling thin sheet materials.
Usage For Center Drill:
1. Installation: Mount the step drill onto a power drill or drill press, ensuring the bit is securely fixed.
2. Positioning: Align the drill bit with the spot where you want to drill, starting with light pressure.
3. Drilling: Gradually increase the pressure. As the bit goes deeper, the hole diameter will increase step by step until reaching the desired size. Each step represents a different hole diameter.
4. Deburring: Continue to drill lightly to ensure the hole edges are smooth and burr-free.
Precautions For Center Drill:
1. Material Selection: Ensure the material being drilled is suitable for a step drill. Extra thick or hard materials may require special handling or a different drill bit.
2. Speed Control: Adjust the drill speed according to the material. Metal typically requires a lower speed, while wood and plastic can be drilled at higher speeds.
3. Cooling: When drilling metal, it is recommended to use cooling fluid or lubricant to prevent the bit from overheating and getting damaged.
4. Safety Protection: Wear protective eyewear and gloves to prevent injury from flying debris and hot metal.
5. Stable Operation: Ensure the workpiece is securely fixed to prevent it from slipping or moving during drilling, which could cause the bit to break or the hole to be inaccurately sized.
