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

Index: SR01.06.022.060.06R

Industrial three-flute spiral end mill made from solid carbide (VHM) with positive geometry (upward chip removal). The arrangement of three cutting edges (Z3) ensures higher rigidity of the body and the ability to work with significantly higher feed rates compared to two-flute tools. The right-hand spiral effectively removes chips upwards, guaranteeing a clean and tear-free bottom edge. Designed for highly efficient cutting, grooving, and edge routing in aluminium, plastics, and composites on CNC machining centres and overhead milling machines. The finishing geometry of the cutting edges combined with polished chip flutes prevents chip build-up on the tool body. The ground shank in class H6 accuracy eliminates radial run-out, 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 finishes.
• Positive geometry (upward chip removal): The right-hand spiral lifts the chips upwards, effectively preventing tearing and fraying on the underside of the machined plate.
• Polished chip flutes: The mirror-like surface of the spiral reduces friction and prevents chip welding onto the tool body.
• Finishing geometry of the cutting edge: 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 grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.

Application and range of use:

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

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