High-frequency brushless motor, high power, much more powerful than chain saw and the body saw blade properties red brick wall test results 3 minutes 2 meters. Chain saw takes 15-20 minutes. Adjustable Cutting Depth:Features an electric free adjustment mechanism, allowing for precise cutting depths from 30mm to 60mm. Body protection system: There is a gyroscope on the handle. If the saw blade kicks back (caused by excessive cutting speed or encountering a hard object, the saw blade slides upward due to inertia, and the handle is pressed down), it will be judged as rebo Brushless Technology:Utilizes brushless technology, providing a longer lifespan and increased efficiency for the wall cutting saw. The whole machine uses a circular saw blade with a thickness of about 3mm, which belongs to the nature of a cutting blade. It has high cutting efficiency and can cut a wide variety of materials, such as, Manufacturer: WAFOHSR
