Showa-Dapra BT50-BSA62-195 BT50 Tool Holder Chuck

Showa-Dapra BT50-BSA62-195 is an angled boring bar (A-type) designed for BT50 spindle tooling, pairing a BT50 shank with a 195 mm overall length to fit standard BT50 toolholders on CNC milling centers. The model indicates a nominal 62 mm bore-diameter configuration, with distributor data noting a 62–90 mm workpiece bore range, enabling large-diameter hole boring in setups that require off-axis reach. Some listings specify an aluminum (AL) shank and list a weight around 6.1 kg, with catalog data showing D 62 and L 195 as key dimensions for this BT50-BSA62-195 configuration. This tooling combo provides rigid support during cutting and helps minimize deflection on longer reaches, making it suitable for precision boring tasks on BT50-capable machines in metalworking environments where large holes must be machined to tight tolerances. The BT50-BSA62-195 is commonly used in applications requiring off-axis boring geometry to access large-diameter holes in workpieces such as automotive components or other metal parts, where reliable repeatability and compatibility with BT50 spindles are essential for consistent production results.
