Bimal Tool Spiral Cutter VHM Ball Nose for Aluminium and Plastics with Upward Chip Ejection – for 3D Carving and Machining

Index: SQ31.64.254.635.64R

Industrial bimal tool spiral cutter made from solid carbide (VHM) with a ball nose geometry and positive upward chip ejection. The arrangement of two cutting edges (Z2) with a full radius on the ends enables precise contour milling, carving, engraving, and machining of curved surfaces in 3D without leaving sharp steps. The right-handed screw line effectively lifts the chips upwards, preventing accumulation in the cutting zone. Dedicated to finishing, cutting, and joining in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished flutes prevents chip build-up on the body. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine’s drive system.

Design Advantages and Technical Features:

• Balt Nose Geometry: Full radius on the tool ends allows for precise 3D modelling, machining of spatial surfaces, and smooth transitions into internal radii.
• Dual Blade Design Z2 (positive): Two cutting edges increase the rigidity of the cutter and allow for efficient work with smooth guidance in the material.
• Positive Geometry (upward ejection): The right-handed spiral lifts the chips upwards, protecting the lower machined surface from scratches caused by chips.
• Polished Flutes: The mirror-like surface of the spiral reduces friction and effectively prevents chips from sticking to the body.
• Solid Carbide (VHM): The rigid and wear-resistant structure of the solid reduces vibrations and guarantees dimensional stability with precise details.
• Low Shank Roughness (Ra ≤ 0.3 µm): The ground surface of the shank secures against 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 3D machining, carving, engraving, cutting, and joining in aluminium and plastics on CNC machining centres.

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