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

Index: SQ02.12.025.120.12R

Industrial two-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal) and body necking (undercut/shank). The arrangement of two cutting edges (Z2) ensures high rigidity and stability during operation, allowing for increased feed rates without the risk of vibrations. The undercut eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating. The right-hand helical geometry efficiently directs chips upwards, guaranteeing a clean, smooth, and tear-free bottom edge. Also suitable for precise cutting and edge jointing and finishing in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and overhead milling machines. The ground shank in accuracy class H6 eliminates radial run-out, protecting the machine drive system.

Construction advantages and technical properties:

• Optimised design with undercut (shank): The necking of the body eliminates the risk of tool collision with the material during deep milling, facilitates free chip removal, and reduces friction, protecting the workpiece from overheating.
• Two-flute Z2 design (positive): Two cutting edges provide higher processing efficiency and allow for operation at higher feed rates while maintaining smooth cutting.
• Positive geometry (upward chip removal): The right-hand spiral lifts chips upwards, effectively preventing tearing and fraying on the underside of the workpiece.
• Polished chip flutes: The mirror finish of the spiral reduces friction and prevents chips from welding to the tool body.
• Finishing edge geometry: Precise finishing of the cutting edges ensures quality and smoothness of the machined surface.
• Monolithic carbide (VHM): The rigid and wear-resistant structure of the monolith 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 in 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 designed for cutting operations and edge jointing and finishing in aluminium, profiles, and plastics on CNC machining centres.

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