55° Tapered Ball Nose End Mill - 2-Flute Coated Tungsten Carbide Tapered Router Bit for Mold Steel & Hardened Alloys
55° Tapered Ball Nose Design
Precision-engineered taper angle (55°) ensures smooth transitions in complex contours and deep cavities, ideal for 3D mold machining, die sinking.
Ball nose tip enables intricate spherical groove carving and fine surface finishing on hardened steels up to HRC 55.
Advanced TiSiN Coating
TiSiN coating enhances hardness and reduces friction, extending tool life 3x in high-temperature environments like machining mold steel and stainless steel.
2-Flute Spiral Geometry
Dual-flute design with 30° spiral angle optimizes chip evacuation, reducing heat buildup and preventing workpiece deformation during high-speed CNC milling.
Ultra-Fine Tungsten Carbide Core
Made from German-grade submicron tungsten carbide, offering exceptional rigidity and wear resistance for prolonged heavy-duty use on hardened alloys.
Versatile Applications
Suitable for vertical and side milling of mold cavities, automotive dies, and titanium alloy components, achieving surface roughness ≤Ra 0.8μm.
The 55° Tapered Ball Nose End Mill is engineered for precision machining of hardened mold steels (HRC55) and exotic alloys. Its tapered design minimizes tool deflection in deep-pocket milling, while the ball nose tip delivers flawless 3D contours for automotive molds, medical implants, and aerospace parts.
The TiSiN coating acts as a thermal barrier, enabling dry or wet machining at speeds up to 18,000 RPM without compromising edge sharpness. Combined with the 30° spiral flutes, chips are evacuated efficiently, reducing recutting and prolonging tool life. This end mill excels in both roughing and finishing phases, eliminating the need for frequent tool changes.
