Using the DeWalt DWA54058 drill bit is easy. First, make sure your dust extractor is properly set up and working. Then, connect the bit directly to the DeWalt Airlock System on the dust extractor. Once it's securely attached, you can start drilling. This bit is designed to fit any SDS max hammer and works with all major brands. When drilling, the diamond grit will help the bit last longer, even in tough applications. Remember, this bit is part of DeWalt's cordless anchoring solution, so it's great for installing adhesive anchors quickly. As for maintenance, after each use, clean the bit to remove any dust or debris. Store it in a dry place to prevent rust. Also, always follow OSHA safety guidelines when using power tools. This bit is OSHA Table 1 compliant, which means it helps reduce your exposure to dust, but it's still important to take proper safety precautions.
