Feature: 1. BRUSHLESS MOTOR: Adopts brushless motor, with high efficiency, low heat generation, low noise, and vibration, extending the service life of the machine, the rotation speed is up to 18000rpm and the threading speed is 40m/min. 2. 50FT TEP WIRE: The wire is made of excellent TEP material, with good wear resistance, with a flexible steel tip, which can smoothly pass through all types of pipes and conduits, not prone to aging or getting stuck in the conduit. 3. 6 GUIDE WHEELS: The wire is clamped by 6 steel guide wheels, the force for winding and loosening is greater than regular fish tape, the wheels can control the wire speed to avoid jamming and slipping, can pass through up to 6 right angle pipes. 4. VARIABLE SPEED: The electric pipe threading machine has a variable speed function, allowing users to adjust the machine speed to adapt to the task at hand, achieving higher accuracy and efficiency in work. 5. APPLICABLE INTERFACE: Powered by lithium batteries (not included), suitable for BL1830B‑2 BL1850‑2 BL1850B‑2 BL1840B BL1820B BL1860B‑2 BL1830 BL1840 BL1850 BL1860 BL1815 BL1430 BL1450 BL1440 and other battery interfaces.
