印度采购需求：数控刀具，高速钢钻头

I'm looking to gather more detailed information regarding your offerings of tapper shank drills. Specifically, I'm interested in understanding the available sizes, the materials used in production, and any coatings that are applied. Additionally, if you could provide insights into the manufacturing processes you utilize, it would be greatly appreciated. Moreover, I'd like to know about your pricing structures, including any bulk purchase discounts or lead times for large orders. If you have product catalogs or specifications that can be shared, that would also be helpful in making a more informed decision. Looking forward to your prompt response!
