印度采购需求：Din338 高速钢钻头、金属高速钢钻头、麻花高速钢钻头、钴麻花钻头、高速钢钴麻花钻头、金属高速钢钻头套装

I'm interested in placing an order for auger drill bits. Specifically, I would like to procure three different sizes in bulk: 1000 pieces of the first size, 1000 pieces of the second size, and 500 pieces of the third size. If available, I prefer the screw tips to be carbide coated for enhanced durability. Could you please provide a detailed quotation, including pricing, lead time, and payment terms? It would be great if you could send this information directly to my email. Looking forward to your prompt response!
