When machining ultra-high hardness materials at the HRC65 level, the roughing stage often determines overall machining efficiency and tool cost control. These materials exhibit high cutting resistance, rapid tool wear, and high sensitivity to vibration, which place higher demands on the tool’s structure, material properties, and stability. Under such conditions, ordinary roughing milling cutters struggle

In stainless steel part machining, selecting the right bull nose milling cutter has a direct impact on machining efficiency, surface quality, and overall production stability. Compared with traditional square shoulder milling cutters, bull nose milling cutters distribute cutting forces more evenly during edge machining and radius transitions. This reduces tool chipping, minimizes vibration, and significantly

HRC65 corner radius end mills are widely used in high-hardness tool steel machining due to their rounded edge design, which effectively distributes cutting forces and improves tool life and machining stability. Compared to traditional flat-bottom end mills, corner radius end mills reduce the risk of chipping while providing higher precision and better surface quality when

In mold and die manufacturing, the choice of cutting tools directly affects processing efficiency, cavity accuracy, and subsequent polishing costs. Among these tools, ball nose milling cutters have become indispensable due to their stable performance when machining complex curved surfaces and deep cavities. Whether working on plastic molds, die-casting molds, or precision stamping molds, there

In precision machining of hardened steel, tool performance directly impacts machining stability, surface finish, and overall production efficiency. When workpiece hardness reaches or exceeds HRC60, conventional tools often fail to meet the demands for long-term continuous machining in terms of wear resistance, edge strength, and thermal stability. This makes the HRC65 ball nose end mill
