San-ei Kousan Co., Ltd. has been engaged in trading operations since 2005 to meet customer demands and has contributed to cost reduction for customers with overseas products. Since August 2015, our customers have begun to fully adopt Chinese-made diamond wheels, resulting in significant cost savings. It took about three years to establish quality, but we are now able to provide stable and high-quality products. Therefore, starting in 2016, we decided to begin sales activities for diamond wheels not only to our existing customers but also to new customers. We kindly ask companies that use diamond wheels to reach out to us and evaluate our diamond wheels.
