Wiha TorqueVario-S Bit Set, 59 Piece, In/lbs Handles (28589)

Most torque work goes wrong at the low end, where one oversized driver gets pressed into service for a spec it was never calibrated to hit. The 59 Piece TorqueVario-S Bit Set solves that with three dedicated handles covering 15-80 in/oz, 5-10 in/lbs, and 10-50 in/lbs — each repeatable, each documented, each sized to the job in front of you. Tools marked with a serial number ship with a calibration certificate, giving you verified accuracy for compliance, auditing, and quality assurance requirements. The enclosed mechanism design seals internal components against contamination, making these drivers well suited to production-controlled and cleanroom-adjacent environments. Accuracy is certified to 5,000 cycles, and the set meets ASME B107.14m, EN ISO 6789, and BS EN 26789. German engineering runs through every component. Blades are forged from premium tool steel and precisely heat-treated for years of service life. The SoftFinish ergonomic handle puts maximum surface area in your palm for controlled force and less fatigue through long assembly runs. The set arrives in a storage case with Hex, Torx, Phillips, Slotted, and Pozi bits and sockets, ready for immediate deployment on the line or in the field.
