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

Index: SR01.20.060.120.20R

Industrial three-flute spiral end mill made from solid carbide (VHM) with positive geometry (upward chip evacuation). The arrangement of three cutting edges (Z3) provides higher rigidity of the body and allows for significantly higher feed rates compared to two-flute tools. The right-hand spiral effectively evacuates chips upwards, ensuring a clean and tear-free bottom edge. Designed for highly efficient cutting as well as edge grooving and trimming in aluminium, plastics, and composites on CNC machining centres and overhead spindle milling machines. The finishing geometry of the edges combined with polished chip 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 Design Z3 (Positive): Three cutting edges allow for a significant increase in feed speed while maintaining smooth cutting and high-quality finishing.
• Positive Geometry (Upward Chip Evacuation): The right-hand spiral lifts the chips upwards, effectively preventing tearing and chipping 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: Precision finishing of the cutting edges ensures a smooth surface after machining.
• 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 to Class G2.5: Balancing in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Intended Use and Scope of Application:

The tool is intended for cutting operations as well as grooving and trimming edges in aluminium, plastics, and composite materials on CNC machining centres.

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