印度采购需求：金属钻头、木材钻头、石工钻头、孔锯、丝锥和板牙、锯片

I'm looking for a range of power tools suitable for both professional and DIY use. Ideally, the tools should cover various categories such as drills, saws, and sanders, ensuring versatility and efficiency for different projects. I'd like to understand the specifications, available features, and functionalities of each tool, along with their performance capabilities. Additionally, it would be great to know about the materials used in their construction and any safety features that are incorporated. I'm also interested in bulk pricing, lead times for delivery, and the warranty options you offer. If you have any catalogs or detailed product sheets, please send them over, as I'm eager to explore the options before making a decision.
