Ball nose spiral router bit for aluminum & plastics VHM Z2 D5 I12 L60 S5 RH Finishing positive

Bimetallic spiral cutter VHM ball-nosed for aluminium and plastics with upward chip discharge – for sculpting and 3D machining

Index: SQ31.05.012.060.05R

Industrial bimetallic spiral cutter made of solid carbide (VHM) with ball-nose geometry (Round Nose) and upward chip discharge (positive). The arrangement of two cutting edges (Z2) with a full radius at the ends enables precise contour milling, sculpting, engraving, and machining of curved 3D surfaces without leaving sharp steps. The right-hand screw line effectively lifts the chips upwards, preventing their accumulation in the cutting area. Dedicated to finishing work, cutting, and bonding in aluminium, plastics, and composite materials on CNC machining centres and overhead spindle milling machines. The finishing geometry combined with polished flutes prevents chip adhesion to the cutter body. Ground shank in precision class H6 eliminates radial runout, protecting the machine drive system.

Design advantages and technical properties:

• Ball-nose geometry (Round Nose): Full radius at the tool ends allows for precise 3D modelling, milling of spatial surfaces, and smooth transitions into internal radii.
• Bimetallic Z2 design (positive): Two cutting edges increase the rigidity of the cutter and allow for efficient operation with smooth guidance within the material.
• Positive geometry (upward chip discharge): Right-hand spiral lifts chips upwards, protecting the machined lower surface from scratches by the chips.
• Polished flutes: The mirror surface of the spiral reduces friction and effectively prevents chip adherence to the body.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid carbide reduces vibrations and guarantees dimensional stability during precise detailing.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing compliant with ISO standards ensures vibration-free operation at very high speeds.

Intended use and application range:

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

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