Spiral router bit for aluminum & plastics VHM Z1 D6,35 I25,4 L63,5 S6,35 RH Finishing positive

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

Index: SP01.64.254.635.64R

Industrial single-edged spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting, as well as jointing and edge finishing in aluminium, composite materials, and plastics on CNC machining centres and machining mills. The finishing geometry with a single edge (Z1) combined with a polished fluting effectively prevents welding and material build-up on the cutting edge. The right-hand spiral quickly 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.

Design advantages and technical properties:

• Single-edge Z1 design (positive): The single cutting edge provides ample chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished fluting: The mirror finish of the spiral surface prevents welding and sticking of aluminium chips to the cutter body.
• Finishing blade geometry: Precisely ground edge allows for a clean surface without the need for additional finishing operations.
• Solid carbide (VHM): The rigid VHM structure 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 prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in G2.5 class: Balancing according to ISO standards ensures vibration-free operation at very high rotational speeds.

Intended use and application range:

The tool is intended for cutting operations, as well as jointing and edge finishing 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.
