Long straight collet holder for CNC milling, 17mm extension rod with wrench (C10ER11M100L 100mm)

Discover our high-precision collet chuck, designed to meet the demands of the most rigorous machining operations. Made of 40Cr steel, this chuck offers excellent vibration absorption, exceptional concentricity, and high stability during machining. Its one-piece design ensures high concentricity between the inside and outside. Precise manufacturing control guarantees stable performance and optimal concentricity for flawless results. Ideal for high-precision machine tools, this collet chuck has undergone internal bore grinding, significantly extending its service life compared to ordinary chucks. Thanks to a case hardening and tempering process, its hardness reaches 45-46 HRC. This manufacturing process enhances the fatigue resistance of the interface, ensuring increased durability and robustness. It offers a convenient clamping range of 1 to 7 mm (0.04 to 0.28 inches). Its stable structure ensures excellent performance and a long service life. The head diameter is approximately 16 mm (0.63 inches) and the shank diameter is approximately 10 mm (0.39 inches). It is compatible with ER11 type collets and has an M thread. Your order includes: 1 x Collet Holder (Chuck) 1 x Wrench
