EMR/EMRW Series Round Nose Milling Cutter Shanks

Our round nose milling cutter shank (including popular EMR/EMRW series) delivers exceptional value for precision machining: engineered with a precision-ground round nose, it ensures smooth complex contour machining (Ra ≤ 0.8μm) for mold, automotive, and aerospace parts, while our CNC round nose milling cutter shank maintains ≤0.005mm concentricity for stable high-speed operation. Crafted from heat-treated 40CrNiMoA alloy steel with a thickened body, it offers 3000N anti-deformation rigidity and vibration damping, reducing chatter at up to 8000rpm and extending tool life by 50% for tough materials like alloy steel and titanium. Designed for universal compatibility, it fits most CNC machineswith CAT40/BT40 tapers, enables 30-second tool changes, and works seamlessly with aluminum to stainless steel. Each shank features TiAlN/TiCN multi-layer coating (HV ≥ 3000) for corrosion/wear resistance, lowering replacement costs, and we offer tailored solutions—extended lengths (100-200mm) for mold makers, quality-certified (ISO 9001, DIN 6535) options for aerospace, and custom modifications—to meet industry-specific needs.
