The development of double-edged milling cutter tips has closely followed the evolution of CNC machining and woodworking advertising industries, gradually upgrading from traditional manual tools to modern precision carving tools. Early processing relied solely on carbon steel straight-edged chisels, which had simple structures, lacked spiral chip evacuation grooves, and exhibited poor wear and heat resistance. Low-speed processing often resulted in clogging and edge chipping, meeting only basic wood carving and rough machining needs with extremely low precision and efficiency. With the widespread adoption of high-speed steel materials and the emergence of first-generation CNC equipment, standardized straight-slot double-edged chisels were officially introduced. The shank and taper achieved unified specifications, making them compatible with early engraving machines and milling equipment, becoming industry-standard tools. However, issues such as poor chip evacuation and subpar finishing effects persisted. After the 1990s, breakthroughs in carbide metallurgy and tool grinding technology led to core innovations in cutting tools, upgrading them to modern double-edged milling cutter tips featuring double-spiral chip pocket structures and monolithic tungsten steel forging. The new tools addressed problems like clogging and edge blurring, while also supporting both rough material shaping and fine relief carving, as well as small-scale lettering processes.

    To this day, the tool has continued to optimize its material and craftsmanship, becoming a mainstream precision tool in woodworking and advertising engraving due to its advantages of high wear resistance, excellent adaptability, and multi-functional use.
