One-blade spiral cutter VHM for aluminium with upward chip removal – clean bottom edge and efficient chip evacuation

Index: SP01.32.635.635.32R

Industrial one-blade spiral cutter made of solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting, as well as welding and edge levelling in aluminium, composite materials, and plastics on CNC machining centres and overhead spindle milling machines. The finishing geometry with a single blade (Z1) combined with a polished chip groove effectively prevents chip welding and material buildup on the cutting edge. Right-hand spiral swiftly evacuates chips upwards, protecting the cutting zone from overheating and guaranteeing a clean, finished edge surface. The precision-ground shank in class H6 eliminates radial runout, protecting the machine drive system and ensuring a high level of machining stability.

Design advantages and technical properties:

• One-blade design Z1 (positive): The single cutting edge provides a large chip space, enabling immediate chip evacuation and reducing cutting resistance.
• Polished chip groove: The mirror-finished surface of the spiral prevents the welding of aluminium chips to the cutter body.
• Finishing blade geometry: The precisely sharpened edge allows for a clean surface 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 taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high rotational speeds.

Purpose and range of applications:

The tool is intended for cutting, welding, and edge levelling operations in aluminium and composites on CNC machining centres.

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