Three-flute VHM Spiral End Mill for Aluminium and Plastics with Upward Chip Evacuation – Clean Bottom Edge

Index: SR01.04.012.060.04R

Industrial three-flute spiral end mill made from solid carbide (VHM) with positive geometry (upward chip evacuation). The arrangement of three cutting edges (Z3) ensures higher rigidity of the body and the ability to operate at significantly higher feed rates compared to two-flute tools. The right-hand spiral efficiently evacuates the chips upwards, guaranteeing a clean and tear-free bottom edge. Designed for highly efficient cutting, welding and edge trimming in aluminium, plastics and composites on CNC machining centres and overhead milling machines. The finishing geometry of the cutting edges combined with polished flutes prevents the accumulation of chips on the tool body. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Structural Advantages and Technical Properties:

• Three-flute Z3 (positive) design: Three cutting edges allow for a significant increase in feed speed while maintaining smooth cutting and high finish quality.
• Positive geometry (upward chip evacuation): The right-hand spiral lifts the chips upwards, effectively preventing fraying and tearing on the underside of the workpiece.
• Polished flutes: The mirror-like surface of the spiral reduces friction and counteracts chip welding to the tool body.
• Finishing blade geometry: Precision finishing of the cutting edges ensures a smooth surface after machining.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid guarantees a long tool life and dimensional accuracy.
• 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 balance in class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high speeds.

Intended Use and Scope of Application:

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

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