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 to source high-quality carbide drills for our upcoming projects. We're particularly interested in various sizes and specifications to meet different drilling requirements. Please provide details on your product range, including any relevant tech specs and pricing info. Additionally, it would be great to know about your lead times and whether you have options for bulk orders. If there are any certifications or quality standards your products meet, please include that info as well. I'm eager to explore potential collaboration opportunities with your factory.
