BT30-ER11-70 CNC tool holder for high-precision milling (0.005mm) with wrench

Discover our high-precision CNC tool holder, model BT30-ER11-70, designed for exceptional performance and increased durability. Made from 20CrMnTi and carbon steel, this tool holder undergoes case hardening and tempering, resulting in a high surface hardness (>HRC56°) and remarkable resistance to wear and fatigue. Its design incorporates a one-piece construction for both the inner and outer body, ensuring high concentricity and optimal stability during operation. The grinding of the inner bore makes it perfectly suited for high-precision machine tools, significantly extending its service life compared to ordinary tool holders. With a clamping range of 1 to 7 mm and a guaranteed accuracy of ≤0.005 mm, it offers absolute reliability. It supports speeds up to 10,000 rpm, enabling fast and efficient operation. The usable shank length is approximately 70 mm, and its rough surface is ≥0.8 mm. Your order includes: 1 tool holder, 1 wrench, and 1 storage case for easy protection and storage.
