Key features

  • •Premium M2 HSS Construction for Durable CNC Milling:crafted from high-grade M2 High-Speed Steel—ideal for industrial cutting tools and machinist tools. It withstands intense heat and friction during CNC milling, maintaining a sharp edge longer than standard options. This durability reduces long-term tooling costs, making it a cost-effective choice for metalworking, mold making, and rough milling tasks.
  • •Design for Versatile Metal Cutting: M2 HSS with rigid construction to resist chipping—perfect as a tool bit for mill and milling cutter for metal. It excels at machining non-ferrous metals (aluminum, copper, zinc alloys) and ferrous materials like medium-carbon steels (45# steel), ordinary alloy structural steels (20Cr, 40MnB), annealed stainless steels (304, 316), and free-cutting steels (Y15).
  • •Efficient Chip Evacuation for Smooth Rough Milling Results: The 3-flute design of our square end mill bit balances the chip clearance of 2-flute tools (preventing clogging in deep slots) and the smooth finish of 4-flute options—critical for CNC milling and metal cutting tools. This allows faster feed rates without sacrificing quality, ensuring clean cuts even during rough milling of metals like aluminum or 45# steel, reducing post-processing time.
