Rotary Slip and Adjustable Torque Driver, 2-15 cNm, 1/4'' Hex

The Tohnichi RTD15CN-L Rotary Slip Adjustable Torque Screwdriver is a precision torque tool engineered for accurate, repeatable fastening in low-torque assembly, inspection, electronics, laboratory, and precision manufacturing applications. With an adjustable torque range of 2–15 cN·m and fine 0.1 cN·m increments, it delivers exceptional control for delicate fastening tasks where consistency is critical.

The RTD15CN-L features Tohnichi's proven rotary slip mechanism, which emits a distinct tactile and audible click when the preset torque is reached. Once the target torque has been achieved, the internal clutch automatically slips, preventing additional torque from being applied and significantly reducing the risk of over-tightening, stripped threads, or damaged components.

Torque adjustments are quick and simple using the external graduated scale. Users can rotate the screwdriver body to the desired setting and secure it with the integrated black locking ring, helping maintain consistent torque throughout production or service operations. The hexagonal body design prevents the tool from rolling off work surfaces while improving handling and workplace safety.

Designed for professional environments, the RTD15CN-L incorporates Tohnichi's durable toggle clutch torque detection mechanism for long service life and dependable repeatability. The driver accepts standard 1/4" hex drive bits (sold separately), making it compatible with a wide variety of fastening applications.

Each screwdriver is supplied with a Tohnichi Factory Certificate of Calibration from Japan for quality assurance. Optional ISO/IEC 17025 accredited calibration certificates are also available for organizations requiring traceable calibration documentation. The RTD15CN-L complies with ISO 6789 Type II Class D calibration procedures and is suitable for worldwide industrial use, including European manufacturing environments.

Whether used in electronics manufacturing, medical device assembly, aerospace components, precision instruments, or quality control operations, the Tohnichi RTD15CN-L delivers the accuracy, durability, and repeatability professionals expect from one of the world's leading torque tool manufacturers.
