Single-Edge Spiral Milling Cutter VHM for PLEXI with Upward Chip Ejection – Clean Bottom Edge and Efficient Chip Removal

Index: ST28.02.006.060.03R

Industrial single-edge spiral milling cutter made from solid hard metal (VHM) with positive geometry (upward chip ejection). The tool is equipped with a small helix angle, effectively preventing lifting and vibrations of the processed material. It performs excellently in precise cutting, splicing, and edge trimming of thin materials with a thickness of 1 mm to 8 mm on CNC machines and vertical spindle mills. The finishing geometry with a single blade (Z1) combined with a polished chip flute prevents clogging and melting of the material. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system and ensuring machining stability.

Construction Advantages and Technical Properties:

• Dedicated to thin materials (1–8 mm): Reduced spiral eliminates upward pulling forces, preventing the lifting of flimsy sheets.
• Single-Blade Z1 (positive) Design: The single cutting edge allows for efficient chip removal, minimizing friction and the risk of overheating the material.
• Polished Chip Flute: The mirror surface of the spiral prevents chips from adhering and re-welding to the tool body.
• Finishing Edge Geometry: Precisely sharpened edge guarantees perfect edge quality without fraying.
• Low Shank Roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic Balancing in Class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high speeds.

Intended Use and Application Scope:

The tool is designed for cutting, splicing, and edge trimming operations on thin plastic sheets in CNC machining centres.

Used in the processing of materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites like CORIAN® and HPL.
