Ball nose spiral router bit for aluminum & plastics VHM Z2 D3 I10 L60 S6 RH Finishing positive

Bimetallic spiral end mill VHM ball nose for aluminium and plastics with upward chip removal – for 3D sculpting and machining

Index: SQ31.03.010.060.06R

Industrial bimetallic spiral end mill made from solid carbide (VHM) with a ball nose geometry and upward chip removal (positive). The arrangement of two cutting edges (Z2) with a full radius on the faces allows for precise contour milling, sculpting, engraving, and machining of curved surfaces in 3D without leaving sharp edges. The right-hand helical flute effectively lifts the chips upwards, preventing accumulation in the cutting zone. Designed for finishing work, cutting, and welding in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished chip flutes prevents material from sticking to the body. The ground shank in class H6 accuracy eliminates radial runout, protecting the machine’s drive system.

Construction advantages and technical properties:

• Ball nose geometry: Full radius on the tool's faces enables precise 3D modelling, milling of spatial surfaces, and smooth transitions in internal radii.
• Bimetallic Z2 construction (positive): Two cutting edges increase the stiffness of the mill and allow for efficient work with smooth leading in the material.
• Positive geometry (upward chip removal): Right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches caused by chips.
• Polished chip flutes: Mirror surface of the spirals reduces friction and effectively prevents chip adhesion to the body.
• Solid carbide (VHM): Rigid and wear-resistant monolith structure reduces vibration and guarantees dimensional stability in precision details.
• Low surface roughness of the shank (Ra ≤ 0.3 µm): Ground surface of the shank prevents 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 scope:

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

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