Sumake’s Current Control Screwdriver, SCT-20i, is a specialized tool designed to provide torque and angle control of a fastener during insertion tasks. This tool is useful in applications where a specific torque and angle are critical for proper assembly, such as in manufacturing or electronics assembly.

The Current Torque Control feature enables users to regulate the tool’s torque during operation by adjusting its current draw. This ensures optimal tightening without the risk of over-torquing or under-torquing.

Additionally, the Angle Control function allows the tool to automatically shut off once a specified angle of rotation is reached after achieving a predetermined torque range. This feature enhances efficiency and ensures consistent results, particularly in tasks requiring precise angle adjustments for proper assembly.
