Single-flute spiral end mill VHM for aluminium with upward chip removal – clean bottom edge and efficient chip evacuation

Index: SP01.08.022.070.08R

Industrial single-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting as well as welding and edge truing in aluminium, composite materials, and plastics on CNC machining centres and high-speed milling machines. The finishing geometry with a single edge (Z1) combined with a polished chip flute effectively prevents material from sticking and accumulating on the cutting edge. The right-hand spiral design quickly evacuates chips upwards, protecting the cutting zone from overheating and ensuring a clean, finished edge surface. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine’s drive system and guaranteeing a high level of machining stability.

Design advantages and technical properties:

• Single-flute design Z1 (positive): The single cutting edge provides a large chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished chip flute: The mirror finish of the spiral surface prevents aluminium chips from sticking and welding to the body of the mill.
• Finishing edge geometry: Precisely ground edge allows for a clean surface finish without the need for additional finishing operations.
• Solid carbide (VHM): The rigid VHM construction dampens vibrations and ensures a long tool life when working with non-ferrous metals.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing compliant with ISO standards guarantees vibration-free operation at very high rotational speeds.

Intended use and application range:

The tool is designed for cutting, welding, and edge truing operations in aluminium and composites on CNC machining centres.

Used for machining materials such as: aluminium, ALUCOBOND® panels, ALUCOBOND® A2, plastics, and composites such as CORIAN® and HPL.
