Feature: 1. BRUSHLESS MOTOR AND POWERFUL TRACTION: Brushless efficiency is high and powerful because it generates less heat, noise, and vibration, resulting in a better user experience and longer machine lifespan. The rotational speed can arrive 18000rpm, and the threading speed is 40M/min. 2. 50FT TEP WIRE: This wire is made of TEP materials on the market and has a flexible steel tip that can smoothly pass through all types of pipes and conduits. The unique TEP material makes it more difficult to wear. Therefore, it is not prone to aging and getting stuck in the catheter. The length of the TEP line is 50 feet, which is sufficient to accommodate most threaded tasks. 3. UNIQUE GUIDE WHEEL: The wire is clamped by 6 steel guide wheels, and the force for winding and loosening the wire is greater than that of ordinary fish belts. In addition, wheels can control the speed of wires to avoid jamming and slipping. It can pass through up to six 90 ° right angle pipes. 4. LARGE CAPACITY BATTERY: The 21V 2500mAh lithium battery is a high capacity power supply that can provide long lasting operation time for electric threading machines. When fully charged, it can provide 3 to 4 hours of running time. 5. VARIABLE SPEED: The speed of the electric threading machine is adjustable to adapt to the task at hand. Achieve higher accuracy and efficiency in work.
