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

Index: SP01.06.022.060.06R

Industrial single-flute spiral end mill made from solid carbide (VHM) with a positive geometry (upward chip extraction). Designed for efficient and precise cutting, as well as edge welding and levelling in aluminium, composite materials, and plastics on CNC machining centres and overhead spindle mills. The finishing geometry with one cutting edge (Z1) combined with a polished chip flute effectively prevents chip welding and material buildup on the cutting edge. The right-hand helical flute quickly removes the 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 drive system and ensuring a high level of machining stability.

Construction advantages and technical properties:

• Single-flute design Z1 (positive): The single cutting edge provides a large chip space, enabling immediate chip evacuation and reducing cutting resistance.
• Polished chip flute: The mirror finish of the spiral surface prevents chips of aluminium from sticking and welding to the tool body.
• Finishing cutting geometry: The precisely ground edge allows for achieving a clean surface without the need for additional finishing machining.
• Monolithic 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 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.

Application and scope of use:

The tool is intended for cutting operations as well as edge welding and levelling in aluminium and composites on CNC machining centres.

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