Compact in size, powerful in performance!

RAD has originally designed the SDM (Small Diameter Multiplier) gearboxes for the aerospace industry where tool access is limited and quality and precision standards are high. Because of the compact design, the SDM gearboxes provides a solution for applications where tool access to the bolt is restricted and where high torque is needed.

The SDM’s low weight combined with the motorized drive makes work light and easy, no more pulling on manual torque wrenches. Thanks to RAD’s highly advanced torque multiplier technology, these wrenches continue to perform reliably for many years.
