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

Index: SP01.03.012.060.06HR

Industrial single-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting, welding, and edge trimming of aluminium, composite materials, and plastics on CNC machining centres and vertical milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished chip groove effectively prevents chip adhesion and material buildup on the cutting edge. The right-handed spiral flute quickly removes chips upwards, protecting the cutting area from overheating and ensuring 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-flute Z1 (positive) design: The single cutting edge provides a large chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished chip groove: The mirror-finished surface of the spiral prevents chip adhesion and welding of aluminium chips to the body of the mill.
• Finishing geometry of the cutting edge: Precisely sharpened edge allows for achieving a clean surface without the need for additional finishing machining.
• Solid carbide (VHM): The rigid structure of VHM dampens vibrations and ensures long tool life when working with non-ferrous metals.
• Low roughness of the shank (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 to class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high rotational speeds.

Intended use and application range:

The tool is designed for cutting as well as welding and trimming edges 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.
