Double-check measurements to ensure accuracy. 3. **Secure the Stone**: If possible, clamp the stone to prevent movement. For larger, immovable stones, ensure the area is stable and won't shift during drilling. 4. **Use Safety Gear**: Wear safety goggles, gloves, and a dust mask to protect against stone dust and debris. 5. **Drill at a Low Speed**: Start drilling at a low speed to create a small pilot hole. This helps prevent the bit from slipping and ensures precision. 6. **Apply Steady Pressure**: Maintain consistent pressure on the drill. Avoid forcing the drill, as this can cause the bit to overheat or break. 7. **Cool the Drill Bit**: Periodically withdraw the bit to cool it down and remove debris. For harder stones, use water to cool the bit and reduce dust. 8. **Increase Speed Gradually**: Once the pilot hole is established, increase the drill speed slightly. Continue applying steady pressure. 9. **Monitor Progress**: Regularly check the depth and angle of the hole to ensure it meets your requirements. 10. **Finish and Clean**: Once the desired depth is reached, remove the drill bit carefully. Clean the hole and surrounding area of any dust or debris. 11. **Inspect the Hole**: Ensure the hole is clean and free of cracks or chips. If necessary, smooth the edges with sandpaper or a file.

To prevent drill bits from slipping on smooth surfaces, follow these steps: 1. **Center Punch**: Use a center punch to create a small indentation at the drilling point. This provides a guide for the drill bit and prevents it from wandering. 2. **Masking Tape**: Apply a piece of masking tape or painter's tape over the drilling area. The tape increases friction and helps stabilize the drill bit. 3. **Pilot Hole**: Start with a smaller drill bit to create a pilot hole. This initial hole guides the larger bit and reduces the chance of slipping. 4. **Low Speed**: Use a low drill speed when starting the hole. High speeds can cause the bit to skate across the surface. 5. **Proper Bit**: Ensure you are using the correct type of drill bit for the material. For example, use carbide-tipped bits for tiles and glass. 6. **Lubrication**: For metal surfaces, apply a lubricant like cutting oil to reduce friction and heat, which can cause slipping. 7. **Firm Grip**: Hold the drill firmly and apply steady, even pressure. Avoid excessive force, which can lead to slipping. 8. **Drill Guide**: Use a drill guide or jig to keep the drill bit aligned and stable, especially for precision work. 9. **Clamping**: Secure the workpiece with clamps to prevent movement during drilling. 10. **Check Equipment**: Ensure the drill bit is sharp and properly secured in the chuck.
