Three-flute VHM spiral end mill for aluminium and plastics with upward chip evacuation – clean bottom edge

Index: SR01.12.032.090.12R

Industrial three-flute spiral end mill made from solid carbide (VHM) with positive geometry (upward chip evacuation). The three cutting edges (Z3) design ensures higher body stiffness and allows for significantly higher feeds compared to two-flute tools. The right-hand spiral efficiently lifts the chips upwards, guaranteeing a clean and tear-free bottom edge. Designed for highly efficient cutting as well as edge welding and flattening in aluminium, plastics, and composites on CNC machining centres and vertical milling machines. The finishing edge geometry combined with polished chip flutes prevents the body from being clogged with chips. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Design advantages and technical features:

• Three-flute Z3 (positive) design: Three cutting edges allow for a significant increase in feed speed while maintaining smooth cutting and high surface finish quality.
• Positive geometry (upward chip flow): The right-hand spiral lifts the chips upwards, effectively preventing tearing and fraying on the underside of the workpiece.
• Polished chip flutes: The mirror-like surface of the spiral reduces friction and prevents chips from welding to the tool body.
• Finishing edge geometry: Precise finishing of the cutting edges ensures a smooth surface after processing.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid carbide guarantees long tool life and dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the holder 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.

Purpose and application range:

The tool is designed for cutting, edge welding, and flattening operations in aluminium, plastics, and composite materials on CNC machining centres.

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