JR history:

In 1992,Henan Runfa Superhard Abrasives Factory was founded in Shangqiu City of Henan Province, which is already a famous brand amid China's superhard materials industry.

In 2005, Guangzhou JR Diamond Tools Co., LTD. was established in Guangzhou City. We moved our factory to Guangdong province. Our brand "JR" comes from Chinese "JinRui". "Jin'' refers to the diamond in Chinese and "Rui" refers to something sharp, together "JR" holds the connotation of not only our impregnable and precise products but also the consistent and professional service.

In 2016, due to the market strategy, we adjusted our products. We started specializing in resin bond, vitrified bond and electroplated diamond&CBN grinding wheels, which widely used in metal manufacturing industry, such as precision grinding of tungsten carbide, HSS tools. Also our diamond microdermabrasion tips are kind of mature.

In the end of 2019, the company name was changed from ". Guangzhou JR Diamond Tools Co., LTD ". to "JR(Guangdong) New Material Incorporated Company.".
