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

Index: SQ31.13.254.826.13R

Industrial two-flute 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 tips allows for precise contour milling, sculpting, engraving, and machining of curved 3D surfaces without leaving sharp edges. The right-hand spiral effectively lifts the chips upwards, preventing their accumulation in the cutting zone. Designed for finishing, cutting, and welding works in aluminium, plastics, and composite materials on CNC machining centres and overhead spindle milling machines. The finishing geometry combined with polished chip grooves prevents the chip from sticking to the body of the tool. The ground shank in tolerance class H6 eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

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

Application and usage range:

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

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