Two-flute VHM spiral end mill with undercut for aluminium and plastics with upward chip removal – clean lower edge

Index: SQ02.08.020.080.08R

Industrial two-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal) and a neck (undercut). The two cutting edges (Z2) provide high rigidity and stability during operation, allowing for increased feed rates without the risk of vibration. The undercut design eliminates the risk of tool collisions with the material during deep milling, facilitates easy chip removal, and reduces friction, protecting the workpiece from overheating. The right-hand helix efficiently removes chips upwards, ensuring a clean, smooth, and tear-free lower edge. Designed for precise cutting, jointing, and edge finishing in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and overhead milling machines. The ground shank is precision-class H6, eliminating radial runout, protecting the machine's drive system.

Key construction features and technical properties:

• Optimised undercut design: The neck design eliminates the risk of tool collisions with the material during deep milling, facilitates easy chip removal, and reduces friction, protecting the workpiece from overheating.
• Two-flute Z2 (positive) design: Two cutting edges provide greater machining efficiency and allow for operation at higher feed rates while maintaining smooth cutting.
• Positive geometry (upward chip removal): The right-hand helix lifts the chips upwards, effectively preventing tearing and chipping on the underside of the machined panel.
• Polished flute grooves: The mirror-like surface of the spiral reduces friction and prevents chip welding to the tool body.
• Finishing cutting edge geometry: Precise finishing of the cutting edges ensures quality and smoothness of the machined surface.
• 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 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.

Intended use and application range:

Tool intended for cutting operations as well as jointing and edge finishing in aluminium, profiles, and plastics on CNC machining centres.

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