Parlec N40-75EM2 End Mill Tool Holder

The Parlec N40-75EM2 functions as a specialized tooling component engineered to interface standard end mills with the spindle nose of computerized numerical control machinery. Classified as an End Mill Tool Holder, this assembly provides a secure gripping mechanism specifically calibrated to accommodate a ¾-inch internal diameter for tool shaft installation. Its construction prioritizes concentricity and load transfer, supporting the radial forces encountered during vertical milling applications where lateral stability is required. The designated projection measurement of 2¼ inches defines the extension distance from the spindle flange to the tooling tip, directly influencing the depth of cut reachable without interference from the work fixture. Operators utilizing this specific part number require consistent access to precise axial positioning for deep cavity milling operations or profile finishing in medium-to-hard alloy materials. By specifying both the internal diameter and the overall length of the projection, the manufacturer defines the specific reach envelope and compatibility requirements for the intended machining cycle.
