WKK45C是一款PVD涂层硬质合金材质等级，专为铸铁（ISO K类）的钻削加工而设计。该牌号采用红色涂层，不仅直观标识其适用于铸铁材料，也作为磨损指示标记，具有较高的工艺可靠性。
核心定位
WKK45C是针对铸铁钻削开发的专用材质，其核心优势在于多层PVD涂层结构与基体的组合，在应对铸铁加工中的高负荷和高温工况时具有相应表现。该牌号特别适用于ISO K类材料（灰口铸铁、球墨铸铁、蠕墨铸铁）的钻削加工，可应用于汽车、通用机械等行业的大批量生产场景。
涂层技术
涂层类型：多层PVD复合涂层，由耐磨层和支撑层交替构成
涂层体系：TiAlN + TiSiAlCrN + TiSiN多层复合结构（部分规格）
涂层特点：涂层厚度大于标准单层涂层，隔热效果较为突出，有助于降低切削热对基体的影响
硬度/韧性平衡：耐磨层与支撑层的优化组合，硬度与韧性的匹配适用于ISO K材料加工
磨损识别：红色涂层在磨损时可通过颜色变化观察刀具状态，便于判断刀具寿命终点
