Industrial BT50-SMA 25.4-105 Tool Holder Chuck

Alps Tool BT50-SMA25.4-105 is a BT50-taper shell end mill arbor designed to hold SMA-series shell milling cutters with a 25.4 mm (1 inch) shank and an overall length of 105 mm. Built for BT50 spindle tooling, this arbor provides a compact, rigid interface for shell cutters used in larger-diameter milling operations. The SMA25.4-105 designation identifies the shank size (25.4 mm) and the overall length (105 mm) of the arbor, making it suitable for machines configured for SMA end mills. Use it to mount shell cutters in applications such as face milling, slotting, or contour milling on aluminum and steel workpieces, where a secure shell-mill mounting is required. It is designed to be compatible with SMA end mills and BT50 spindles, delivering consistent runout and clamping stability when properly installed and torqued according to the machine’s guidance. Always confirm compatibility with your specific spindle, end-mill diameter, and holder interface before use, and observe all safety procedures during installation and operation.
