Single-edge spiral milling cutter VHM for aluminium with upward chip removal – clean bottom edge and efficient chip removal

Index: SP01.48.794.635.48R

Industrial single-edge spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting, welding, and edge alignment in aluminium, composite materials, and plastics on CNC machining centres and overhead milling machines. The finishing geometry with a single edge (Z1) combined with a polished chip groove effectively prevents sticking and build-up of material on the cutting edge. The right-hand spiral instantaneously removes chips upwards, protecting the cutting zone from overheating and ensuring a clean, finished edge surface. The ground shank in accuracy class H6 eliminates radial run-out, protecting the machine's drive system and ensuring a high level of machining stability.

Design advantages and technical properties:

• Single-edge design Z1 (positive): The single cutting edge provides a large chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished chip groove: The mirror finish of the spiral surface prevents sticking and welding of aluminium chips to the cutter body.
• Finishing edge geometry: The precisely ground edge allows for a clean surface finish without the need for additional finishing machining.
• 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 surface of the shank prevents slipping in the tool holder and protects the spindle cone 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 intended for cutting, welding, and edge alignment operations in aluminium and composites on CNC machining centres.

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