Featuring a 4F wavy cutting edge geometry, the tool effectively breaks chips into small segments, ensuring smooth chip evacuation. This design minimizes cutting resistance, suppresses vibration, and delivers a high material removal rate. The HRC65-grade substrate exhibits exceptional toughness, offering superior resistance to chipping and wear, making it suitable for a wide range of high-hardness materials. It comes standard with a Nano-AlTiN coating capable of withstanding temperatures exceeding 900°C, thereby significantly extending tool life. The robust core-thickness design ensures high rigidity, resisting bending and vibration to ensure stable machining; this facilitates efficient roughing while simultaneously reducing overall production costs, effectively meeting the demands of machining complex, high-hardness workpieces.
