High Efficiency: With an all-copper motor with 4000W load power, 6500RPM no-load speed, and a sharp diamond blade, it allows you to complete grooving jobs easily and efficiently. Dust-free Grooving: This product can be connected to a pump and a vacuum cleaner (not included) and both can be used at the same time to reduce dust during grooving, reduce environmental pollution, and safeguard the health of the operator. The front guard also helps to reduce dust splashing. Precise Control: You can adjust the grooving depth ( 0-1.18 inches) by adjusting the base plate and adjust the grooving width (0-1.18 inches) by changing the number of saw blades to meet the needs of different specifications of wire pipe laying, the consistency and accuracy of the grooving size. Thoughtful Design: The movable headshell design allows this product to slot 360° without a dead angle, allowing you to work once and reduce the need to change tools. You can install different saw blades to cut different materials. User Friendly: The ergonomic handle, auxiliary handle, and lightweight body are non-slip and easy to grasp, reducing hand fatigue for you. The power lock button allows the machine to work for long periods of time without having to be switched on and off repeatedly, allowing you to concentrate on grooving., Manufacturer: QAXRZCUCD
