【Ultra High Hardness】 The 45HRC material of these turning tools possesses a higher hardness, enabling stable cutting due to its excellent toughness and crack resistance. Black oxide, smooth surface on every turning tool holder, distinguished by tool holder style and shank size. 【Durability and Sharpness】 Carbide blades are tin-plated to ensure long life and sharpness, withstanding higher temperatures compared to ordinary steel tools. It can reduce tool grinding costs and improve cutting efficiency. 【High Performance】 The high-performance lathe tool set offers high grip, impact resistance, and strong, clear speed advantages, capable of cutting larger edges and performing machining operations. Good toughness and hardness, long service life. Good low-temperature impact resistance, enhancing the surface gloss of the cutting pieces. 【Easy to Use】 Quick and easy clamping and replacement mode, requiring only a wrench to complete blade and washer replacement. Profile bars for roughing and finishing, drilling tools for steel processing and light turning. 【Application Scenarios】 For machining steel parts and stainless steel, multi-layer coated CNC turning inserts, cutting tools for turning tool holders. Typically used for threading, turning, grooving, drilling, facing, external grooving, etc., Manufacturer: Techfection
