This precision tool holder motor shaft is designed for ER collet tool holders used in engraving machines and CNC applications. Made from high-quality 42CrMnTi steel, it ensures strong durability and high precision with an accuracy of 0.001 mm. The tail hole is slightly smaller than the nominal size to allow thermal expansion during high-frequency heating assembly, ensuring a secure and stable fit for the spindle. Ideal for precise machining where accurate alignment and reliable holding are critical.
