HRC55 Ball Nose Carbide End Mill, 3-12mm Shank 2-Flute CNC Router Bits R0.5-R6 Spiral Milling Tool For Alloy Steel Stainless Steel Cast Iron(R3x12x75x6D)

Material : Carbide The Ball Nose Milling Cutter has a spherical tip and the cutting edge is distributed along a spherical surface, a design that enables it to make point contact with the surface of the workpiece. When machining free-form surfaces, mould cavities or 3D contours, the tool can accurately reproduce complex geometries with a combination of axial and radial feed movements. The spherical tip disperses the cutting forces through multiple points of contact, significantly reducing machining vibrations and surface roughness. The cutting process is stable and enables highly accurate surface quality to be achieved in small steps. The milling cutters are mostly made of cemented carbide and complemented by high-performance coatings. This combination ensures the tool's wear resistance in high-speed and hard cutting, and improves cutting efficiency by optimising the chipformer design. Suitable for: complex surface machining, mould making, multi-axis machining, hard material machining, high-precision surface treatment.
