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

Index: SP01.95.254.635.95R

Industrial single-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal). Designed for efficient and precise cutting, as well as edge welding and aligning in aluminium, composite materials and plastics on CNC machining centres and vertical milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished fluting effectively prevents adhesion and material build-up on the cutting edge. The right-hand spiral rapidly evacuates the chips upwards, protecting the cutting zone from overheating and guaranteeing a clean, finished edge surface. The ground shank in 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-flute Z1 (positive) design: The single cutting edge provides a large chip space, allowing for immediate chip evacuation and reducing cutting resistance.
• Polished fluting: The mirror finish of the spiral surface prevents adhesion and welding of aluminium chips to the body of the mill.
• Finishing edge geometry: The precisely ground edge allows for a clean surface finish without the need for additional finishing operations.
• Monolithic 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 shank surface prevents slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high spindle speeds.

Intended use and application range:

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

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