The Critical Torque Ultimate Bundle is basically 3 tattoo machines for the price of 1. It features three Critical Torque motor bolts – the 3.5mm stroke (green housing), 4.2mm stroke (black housing), and 5.0mm stroke (grey housing), so you can use a variety of techniques including lining, packing, and shading. The upgraded V3 battery offers up to 15 hours runtime depending on the voltage used and features a 1.5″ colour display. The machine is built with a powerful, custom, German brushless motor and features industry-first precision strike technology which provides a firmer and more consistent needle hit. The innovative stabilising system and the vibration dampening solution provides more control and reduces hand fatigue allowing you to tattoo more comfortably during longer sessions.
