Usage Recommendations
For best results, use the kit with an angle grinder or a cordless drill with an SDS or hexagonal adapter. The diamond drills are ideal for cutting through dense materials such as granite and concrete, while the beveled bits allow for clean edges when shaping holes. The finger bit is useful for enlarging or smoothing existing holes. Always apply lubrication during dry drilling using the built-in ceramic coating to reduce friction. When working on wet surfaces, ensure proper water flow to prevent overheating.
Limitations and Notes
The kit is only designed for flat drilling modes. Impact or hammer modes are not supported and may damage the tool. Use the kit on materials such as stone, masonry, or ceramic tiles, but avoid high-pressure applications. The 102mm drill is best suited for thick substrates and should be used with caution due to its size.
