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

Index: SQ02.08.022.105.08R

Industrial two-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip discharge) and a body taper (undercut/neck). The configuration of two cutting edges (Z2) ensures high rigidity and stability during operation, allowing for increased feed speeds without the risk of vibrations. The applied undercut eliminates the risk of tool collision with the material during deep milling, facilitates the free discharge of chips, and reduces friction, protecting the workpiece from overheating. The right-hand spiral efficiently discharges the chips upwards, guaranteeing a clean, smooth, and tear-free lower edge. Designed for precision cutting, jointing, and edge trimming in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and overhead milling machines. Ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Structural advantages and technical properties:

• Optimised design with undercut (neck): The body taper eliminates the risk of tool collision with the material during deep milling, facilitates the free discharge of chips, and reduces friction, protecting the workpiece from overheating.
• Two-flute Z2 (positive) design: Two cutting edges provide greater machining efficiency and allow for higher feed speeds while maintaining cutting smoothness.
• Positive geometry (upward chip discharge): The right-hand spiral lifts the chips upwards, effectively preventing fraying and tearing on the underside of the machined plate.
• Polished chip grooves: The mirror surface of the spiral reduces friction and prevents chip welding with the tool body.
• Finishing blade geometry: Precise finishing of the cutting edges ensures the quality and smoothness of the machined surface.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid guarantees long tool life and dimensional accuracy.
• Low roughness of the shank (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

The tool is intended for cutting, jointing, and edge trimming operations in aluminium, profiles, and plastics on CNC machining centres.

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