What Est Tools does
EST Tools (恒锋工具股份有限公司, legal name Hengfeng Tools Co., Ltd.) is a Chinese public manufacturer of precision cutting and measuring tools, founded in 1990 and headquartered in Haiyan, Zhejiang. The company is listed on the Shenzhen Stock Exchange ChiNext board under stock code 300488 following a July 2015 IPO that raised 213 million yuan. It operates 800+ employees across three domestic production bases (Haiyan headquarters, Hengfeng Road facility, Wenling Shangyou factory) and two wholly-owned overseas subsidiaries in Michigan, USA (2016) and Salzburg, Austria (2024).
EST Tools offers eight core product families — round broaches, form broaches, cold forming tools, precision measuring tools (gauges), gear cutting tools, milling tools, drilling tools, and taps — organized around three functional categories (spline, gear, thread processing) and three tooling forms (high-speed steel, carbide, indexable). It cites 22 core technologies including five-axis precision control, PVD coating, helical broaching, cold forming, and digital twin design, and holds 32 invention patents and 71 utility model patents. It also operates a CNAS-accredited spline measurement laboratory and is the only Chinese manufacturer (fifth globally) capable of producing planetary internal ring gear helical broaches.
Revenue is generated through one-time sales of precision cutting and measuring tools and high-end production services (precision resharpening, processing technology services, CNAS-certified inspection, custom design, and synchronous new product development). The company sells primarily through direct enterprise B2B sales targeting automotive (SAIC, Deyang Xinrui, Zhuzhou Gear Factory), aerospace (C919 program), power generation (Harbin Turbine), rail transit, and construction machinery customers. Pricing is custom-quoted rather than list-priced. In January 2024 the company issued a 620 million yuan convertible bond to add 1.5 million pieces of high-end precision cutting tool capacity, and in 2025 acquired the tap production line of Guangzhou Conprofe Technology to extend its taps product family.
