D16mm R1.0 Corner Radius Solid Carbide End Mill 4 Flute ENWA CNC Milling Cutter for Steel and Cast Iron Steel Mold CNC Milling

The ENWA CARBIDE END MILLS D16R13590*4F is a high-performance solid carbide corner radius end mill for CNC machining centers. Built with premium solid tungsten carbide blank, optimized flute profile and 4-flute structure, this cutter boasts outstanding rigidity, wear resistance and chip evacuation capability. It maintains stable cutting performance during continuous and mild interrupted roughing and semi-finish milling of steel, cast iron and common structural metals, ideal for batch production of mechanical parts, molds and automotive components.

Reasonably designed flute grooves accelerate chip removal and heat dissipation, ensuring sustained machining accuracy and extended service life during long-term mass processing.

• High-strength solid carbide substrate provides excellent rigidity and anti-chipping performance to withstand medium cutting loads.
• 4-flute design balances machining efficiency and chip space, suitable for side milling, slotting and contour profiling.
• R1.0 corner radius design effectively avoids sharp edge wear and workpiece corner chipping, prolonging tool life and improving part quality.
• Precision ground cutting edges reduce cutting resistance and deliver superior surface finish after machining.
• Integrated straight shank with high concentricity ensures firm clamping and stable operation on standard tool holders.
• Standard dimensions D16R13590 meet the demands of conventional milling and medium-depth machining.

• Carbon steel
• Alloy steel
• Pre-hardened steel
• Grey cast iron
• General structural steel

• Side rough & semi-finish milling
• Contour and cavity machining
