An absolutely fantastic supplier. I would highly recommend Shenzhen Dehuai Technology Co. Ltd to anybody that requires precision-made cutting tools. I issued a very basic drawing to their salesperson, Emma, who organised engineering drawings to international standards and facilitated the bespoke manufacture of an helical cutting block to remarkable precision. I am overwhelmed by their attention to detail and service, and their prices are extremely reasonable. I am thoroughly satisfied with every aspect of the service I have received from Shenzhen Dehuai Technology Co. Ltd and I will be using their services again in the future.
