Ball nose spiral router bit for aluminum & plastics VHM Z3 D12 I25 L70 S12 RH Finishing positive

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

Index: SQ31.12.025.070.12R

Industrial two-flute spiral end mill made from solid carbide (VHM) with a ball-nose geometry and upward chip extraction (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 surfaces in 3D without leaving sharp edges. The right-hand spiral effectively lifts the chips upwards, preventing accumulation in the cutting zone. Designed for finishing work, cutting, and jointing in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished flutes prevents chip adhesion to the body. The ground shank in H6 accuracy class eliminates radial run-out, protecting the machine's drive system.

Design advantages and technical properties:

• Ball-nose geometry: Full radius on the tool tips allows for precise 3D modelling, milling of spatial surfaces, and smooth transitions in inner radii.
• Two-flute Z2 design (positive): Two cutting edges increase the rigidity of the mill and allow for efficient work with smooth guidance in the material.
• Positive geometry (upward chip extraction): Right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches by chips.
• Polished flutes: Mirror finish of the spiral reduces friction and effectively prevents chip adhesion to the body.
• Solid carbide (VHM): Rigid and wear-resistant structure of the solid carbide reduces vibrations and guarantees dimensional stability during precision detailing.
• Low shank roughness (Ra ≤ 0.3 µm): Ground shank surface prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing in G2.5 class: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

Tool intended for 3D finishing, sculpting, engraving, cutting, and jointing in aluminium and plastics on CNC machining centres.

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