The quick-change and adjustment functions allow for flexible adjustment of the cutting angle, enabling precise tire groove cutting. This tool's quick-change design saves time and improves work efficiency, making it ideal for professional tire customization and repair work. Main unit dimensions: 230×100×102 mm (9 inches × 3.94 inches × 4 inches); Handle dimensions: 200×38 mm (7.8 inches × 1.5 inches); Compatible blade sizes: 2-10 mm. The robust and durable construction ensures stable performance during extended use without overheating. The sophisticated floating cutter head design prevents the blade mechanism from contacting the tire surface, thus reducing the impact of tire dirt on electrical efficiency. This helps extend tool life and maintains cutting accuracy even in harsh environments. Tire engraving machines can engrave patterns 2-10 mm wide and 5-7 mm deep on tire surfaces. Equipped with a blade heating system, the machine can engrave "U" and "V" shaped patterns, enabling various tire customizations such as letters or tread patterns.
