美国采购需求：高速钢金属钻头、麻花钻头、钴钻头、钛钻头、六角柄钻头、短钻头

I'm looking to place a bulk order for two different sizes of bits and would also like to explore the possibility of having a custom bit designed specifically for our needs. It would be great if you could provide some detailed quotes for these products. Could you let me know the pricing, available quantities, and any minimum order requirements? If you have any additional options or recommendations for custom designs, I'd love to hear those as well. Looking forward to your prompt response!
