Tohnichi 1.5RTD Adjustable Torque Screwdriver (0.2-1.5kgf.cm) - Precision Tool for Electronics Repair, Watchmaking & Small Appliance Maintenance

I just purchased three (3) Tohnichi RTD-series torque screwdrivers (2-10, 6-22, 10-40) and am thrilled with the build quality and attention to detail. I almost purchased inferior products for nearly the same price and am glad I read about Tohnichi here on Amazon. The gold anodizing is stunning (US/English models), the markings are laser-sharp, and the mechanical fit and finish is top notch. Bits fit snugly in the hex socket and there is a firm, audible snap once you hit the specified torque setting. What's more, each unit included a certificate of calibration, showing the target min/max values (specified within 3%), as well as the actual torque measurement over five (5) different measurements. All were probably closer to 1-2% accuracy, giving me confidence in the durability and precision of this instrument. It's the kind of product that is so well built, you just want to fine something to fasten together to get a sense of how torque screwdrivers can be used to ensure consistent quality in your products or assemblies. You will not be disappointed to purchase one or more of these units. They command a premium price, but worth every penny, even compared to reputable German brands, that have a wider tolerance (6%) for nearly the same money. Well done, Tohnichi.
