Two-flute spiral end mill VHM ball nose for aluminium and plastics with upward chip ejection – for sculpting and 3D processing

Index: SQ31.48.159.635.48R

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

Construction advantages and technical properties:

• Ball nose geometry: Full radius at the tool ends enables precise 3D modelling, milling of spatial surfaces, and smooth transitions in internal radii.
• Two-flute Z2 design (positive): Two cutting edges increase the stiffness of the end mill and allow for efficient work with smooth guiding in the material.
• Positive geometry (upward chip ejection): Right-hand spiral lifts chips upwards, protecting the lower machined surface from scratches by chips.
• Polished chip flutes: Mirror-like surface of the spiral reduces friction and effectively prevents chips from sticking to the tool body.
• Solid carbide (VHM): Rigid and wear-resistant monolithic structure reduces vibrations and guarantees dimensional stability with precision details.
• Low shank roughness (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 according to ISO standards guarantees vibration-free operation at very high speeds.

Intended use and range of application:

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

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