Employing an advanced microcomputer temperature control system, it achieves precise temperature regulation, low power consumption, and excellent heat dissipation. Suitable for various tire groove machining applications, it ensures accurate results every time. This product is easy to use, designed for quick and precise cutting by anyone. The blade can be easily positioned and repositioned to the appropriate depth, resulting in a consistent grooving effect. The blade heating system enables smooth rubber cuts and maintains a precise and consistent cutting depth. Suitable for engraving patterns with widths from 3 to 20 mm and depths from 7 to 16 mm, including U-shaped, V-shaped, and straight-line patterns. The unique suspended head design prevents the blade retaining mechanism from contacting the tire surface, thereby reducing the negative impact of tire dirt on electrical efficiency and extending tool life.
