Single-flute spiral end mill VHM for aluminium with upward chip evacuation – clean bottom edge and efficient chip removal

Index: SP01.13.381.889.13R

Industrial single-flute spiral end mill made from solid carbide (VHM) with positive geometry (upward chip evacuation). Designed for efficient and precise cutting as well as edge welding and levelling in aluminium, composite materials, and plastics on CNC machining centres and overhead milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished chip flute effectively prevents material from sticking and building up on the cutting edge. The right-hand screw line quickly directs the chips upwards, protecting the cutting area from overheating and ensuring a clean, finished edge surface. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system and ensuring a high level of machining stability.

Construction advantages and technical properties:

• Single-flute design Z1 (positive): The single cutting edge provides a large chip space, allowing for immediate evacuation of chips and reducing cutting resistance.
• Polished chip flute: The mirror-finished surface of the spiral prevents chips of aluminium from sticking and welding to the body of the mill.
• Finishing geometry of the edge: The precisely ground edge allows for obtaining a clean surface without the need for additional finishing operations.
• Solid carbide (VHM): The rigid VHM construction dampens vibrations and ensures a long tool life when working with non-ferrous metals.
• Low roughness of the shank (Ra ≤ 0.3 µm): The ground surface of the shank protects against slipping in the tool holder and safeguards the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high rotational speeds.

Intended use and range of applications:

The tool is intended for cutting operations as well as edge welding and levelling 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.
