Two-Flute Spiral Milling Cutter VHM Ball Nose for Aluminium and Plastics with Up-cut – for Sculpting and 3D Machining

Index: SQ31.16.381.889.16R

Industrial two-flute spiral milling cutter made from solid carbide (VHM) with ball nose geometry and upward chip removal (positive). The configuration of two cutting edges (Z2) with a full radius on the ends allows for precise shape milling, sculpting, engraving, and machining of curved surfaces in 3D without leaving sharp edges. The right-hand spiral effectively lifts the chips upwards, preventing their accumulation in the cutting zone. Dedicated to finishing, cutting, and joining work on aluminium, plastics, and composite materials on CNC machining centres and overhead spindle milling machines. The finishing geometry combined with polished flutes prevents chip adherence to the cutter body. Ground shank with accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Structural advantages and technical properties:

• Ball nose geometry: Full radius on the tool ends enables precise 3D modelling, milling of spatial surfaces, and smooth transitions in internal radii.
• Two-flute Z2 construction (positive): Two cutting edges increase the rigidity of the cutter and allow for efficient work with smooth guidance in the material.
• Positive geometry (upward chip removal): Right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches by chips.
• Polished flutes: The mirror-like surface of the spiral reduces friction and effectively counteracts chip adherence to the body.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid reduces vibrations and guarantees dimensional stability in precision details.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank secures against slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

The tool is intended for 3D finishing machining, sculpting, engraving, cutting, and joining in aluminium and plastics on CNC machining centres.

Used for machining materials such as: aluminium, plastics, and composites like CORIAN® and HPL.
