Inquiry (采购产品): Small Hole EDM/Drilling I have a line of tungsten carbide rings and bracelets that I need to have holes drilled for diamond and gold application. When we find a process that works, we will potentially have thousands of these holes to produce. I'll send a drawing and attach pictures of the product when you contact me via email.
