- Direct high-speed roughing to finishing for heat-treated materials below 58°, reducing tool changes and improving machine tool processing efficiency. This enables a smoother transition from roughing to finishing without frequent tooling swaps. - New fine-grained tungsten steel base material with high wear resistance and strength, specially designed for high-hardness and high-speed cutting applications. Built to withstand demanding cutting conditions while maintaining performance. - 4 mm shank fits most CNC machines, engraving machines, and high-speed machines, providing broad compatibility for a range of equipment. - Large core diameter design, while maintaining sufficient chip space, to enhance tool rigidity and overall stability during cutting operations. This improves precision and tool life in demanding milling tasks. Key attributes - Function: High-speed milling with efficient progression from roughing to finishing on hard materials. - Compatibility: 4 mm shank compatible with most CNC, engraving, and high-speed machines. - Size: 4 mm shank; designed for high rigidity with a large core diameter. - Material: Fine-grained tungsten steel core for improved wear resistance and strength. - Performance: Optimized for high-hardness materials and high-speed cutting scenarios. Use scenarios - Scenario 1: High-speed milling of heat-treated steels below 58°, performing both roughing and finishing in a single setup to reduce tool changes and increase production efficiency. - Scenario 2: Die and mold components requiring milling of hard alloys, where high wear resistance and cutting rigidity improve tool life and accuracy. - Scenario 3: Engraving and precise milling on small parts using standard CNC, engraving, or high-speed machines that accept a 4 mm shank, benefiting from strong rigidity and compatibility.
