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

Index: SQ31.16.035.090.16R

Industrial two-flute spiral end mill made of solid carbide (VHM) with a ball nose geometry and upward chip removal (positive). The arrangement of two cutting edges (Z2) with a full radius at the tips allows for precise contour milling, carving, engraving, and machining of curved surfaces in 3D 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 in aluminium, plastics, and composite materials on CNC machining centres and overhead spindle mills. The finishing geometry combined with polished chip flutes prevents the body from getting clogged with chips. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Ball nose geometry: The full radius at the tool's cutting edges 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 mill and allow for efficient work with smooth guidance in the material.
• Positive geometry (upward chip removal): The right-hand spiral lifts the chips upwards, protecting the lower machined surface from scratches caused by chips.
• Polished chip 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 carbide reduces vibrations and ensures 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 in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Purpose and scope of application:

The tool is intended for 3D finishing, carving, 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.
