In the month of Oct. 2017, King Kong Drills Limited received one email with inquiry about 3500pcs tapered button bits with diameters from 32mm, 34mm. 36mm. And 38mm. At the beginning she told us she needed best quality and most of important was she wanted us to offer her the bits with YK05 carbides and 45CrNi3MnV. Everyone knows that steel material and tungsten carbide is expensive and the price must be expensive than other cause we need to make sure what we are selling is what we are promising. After first step conversation by email and phone calls communication, The price we offered her was a little higher than she was expecting, however she would rather gave us a chance to test some of our samples then we would discuss the final buying prices again. Two months passed after we prepared the samples but unluckily we did not successfully delivered the samples we had prepared. But it was not our fault, it was Ms Elena told us she and her partner would come to visit our cooperated factory in December. That was a good news for both us, we believed that she would choose us and buy from us as long as she visited us and was seriously to place an order with us. As time flied by, we had delivered 6000pcs tapered bits to Peru as his partner Mr Eduardo told me they would be our biggest buyer in Peru and also in South America on day. Now we are waiting for more good news from Ms Elena and her partner. Cause we believe in our quality and we have faith in our bits quality and we always believe that only best of best quality with reasonable price can lead the market and have a fruitful business for long time.
