High-efficiency thread trimmer features an integrated suction port and cutting head, trimming excess threads to within 1 mm for a flawless finish, while severed threads are automatically drawn into a 30-liter waste bin, saving time and effort. Powered by a brushless blower motor with 450W rated output, adjustable speed from 3,000 to 28,000 RPM, and suction up to 10 kPa, all while operating below 65 dB for a quiet work environment. Precision cutting mechanism trims threads without damaging fabric or compromising seams, improving production efficiency and reducing costs by delivering impeccable results. Innovative square-profile design offers 35% more thread-collection capacity than conventional models, with an ergonomic handle and display screen for easy speed adjustments. Safety protection: if filter clogs or is misinstalled, a negative-pressure relief valve automatically opens to prevent motor and circuit board damage from overload or overheating.
