Spiral router bit for aluminum & plastics VHM Z1 D12 I42 L90 S12 RH Finishing positive

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

Index: SP01.12.042.090.12R

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

Construction advantages and technical properties:

• Single-flute Z1 (positive) design: The single cutting edge provides a large chip space, allowing for immediate evacuation of chips and reducing cutting resistance.
• Polished chip flute: The mirror finish of the spiral surface prevents the sticking and welding of aluminium chips to the cutter body.
• Finishing blade geometry: Precisely ground edge allows for achieving a clean surface without the need for additional finishing operations.
• Solid carbide (VHM): Stiff 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 shank surface protects against slipping in the tool holder and safeguards the spindle taper from wear.
• Dynamic balancing in G2.5 class: 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 truing operations in aluminium and composites on CNC machining centres.

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