• Broad Compatibility：Designed for seamless integration with CNC milling machines, drill presses, and benchtop drilling systems, this face end mill set supports versatile operations across industrial workshops. Its 50mm cutting diameter and 4-flute design enable efficient material removal while maintaining stability in horizontal boring mills and fixture applications. Precision machinists and workshop technicians will appreciate the universal fit for various machine tool setups.
• Precision Milling Performance：Featuring APMT1604 carbide inserts with 0.005mm accuracy, this 4-flute cutter delivers exceptional surface finishes in alloy steel machining. The optimized blade configuration reduces chatter during high-speed operations on milling machines, making it ideal for creating flat surfaces and squaring workpiece edges. Technical professionals can trust its HRC55-58 hardness for consistent performance across multiple projects.
• Versatile Step Surface Machining：Engineered with reduced downward force design, the 400R cutter excels at creating precise step surfaces and machining thin materials without distortion. The 22mm arbor hole ensures secure mounting for repetitive manufacturing tasks in automotive part production or industrial component fabrication. Ideal for operators requiring reliable retention during extended cutting sessions.
• Extended Tool Longevity：The hardened 40CR alloy steel construction combined with replaceable carbide inserts maximizes cutting tool lifespan. Each insert's multi- design allows indexable rotation, providing cost-effective solutions for high-volume machining environments. Maintenance crews will value the included storage boxes for organized insert management.
• Stable Cutting System：Complete with FMB22 shank extension and 20mm tool holder interface, this kit ensures vibration- operation across compatible machinery. The balanced cutter body design enhances operational safety in vertical milling applications while the ergonomic wrench simplifies insert replacement procedures for efficient workshop workflows.
