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

Index: SP01.04.012.060.06R

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

Structural advantages and technical properties:

• Single-edged design Z1 (positive): The single cutting edge provides a large chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished flute: The mirror finish of the spiral surface prevents chip adherence and welding of aluminium chips to the body of the mill.
• Finishing geometry of the blade: Precisely ground edge enables achieving a clean surface without the need for additional finishing operations.
• Solid carbide (VHM): The rigid VHM construction dampens vibrations and provides long tool life when working with non-ferrous metals.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool 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 rotational speeds.

Intended use and application range:

The tool is designed for cutting operations as well as seam welding and edge straightening in aluminium and composites on CNC machining centres.

Used in the machining of materials such as: aluminium, ALUCOBOND® sheets, ALUCOBOND® A2, plastics, and composites like CORIAN® and HPL.
