High Hardness Bull Nose Carbide End Mill Corner Rounding Cutter 4-16mm Diameter with 0.2-2.0mm Radius
High hardness bull nose carbide end mill with corner rounding capability, designed for precision machining of various materials including cast iron, stainless steel, carbon steel, hardened steel, graphite, composites, and acrylic.
- Large core diameter design enhances rigidity and shock resistance, reducing breakage and extending service life
- Passivation technology removes tool adhesion particles and passivates blades for easier high-hardness material processing
- Triangle large groove with new arc blade and double edge belt enables machining on inclined surfaces without reducing cutting parameters
- Fast chip removal design reduces tool wear and improves cutting efficiency
- Precise chamfering contour prevents product bruising and maximizes blade performance
- Double edge belt effectively removes burrs for smooth hole surfaces with small tolerance range
