Single-blade spiral mill VHM for aluminium with upward chip ejection – clean bottom edge and efficient chip removal

Index: SP01.08.022.060.08HR

Industrial single-blade spiral mill made of solid carbide (VHM) with positive geometry (upward chip ejection). Designed for efficient and precise cutting as well as welding and edge trimming in aluminium, composite materials, and plastics on CNC machining centres and gantry milling machines. The finishing geometry with a single blade (Z1) combined with a polished chip flute effectively prevents sticking and accumulation of material on the cutting edge. The right-hand screw line quickly 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 runout, protecting the machine's drive system and ensuring a high level of machining stability.

Design advantages and technical properties:

• Single-blade design Z1 (positive): A single cutting edge provides a large chip space, enabling immediate chip evacuation and reducing cutting resistance.
• Polished chip flute: The mirror-finished surface of the spiral prevents sticking and welding of aluminium chips to the tool body.
• Finishing blade geometry: Precisely ground edge allows obtaining a clean surface without the need for additional finishing processing.
• Monolith of cemented carbide (VHM): The rigid VHM construction dampens vibrations and ensures long tool life when working with non-ferrous metals.
• Low grip roughness (Ra ≤ 0.3 µm): Ground shank surface 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 range of use:

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

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