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

Index: ST28.04.022.060.06R

Industrial single-edged spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal). The tool is equipped with a small angle of inclination of the helical line, effectively preventing lifting and vibrations of the machined material. It works excellently for precise cutting and edge bonding and trimming of thin materials with thicknesses from 1 mm to 8 mm on CNC machines and milling machines. The finishing geometry with a single edge (Z1) combined with a polished chip flute prevents sticking and melting of the material. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system and ensuring stability during machining.

Structural advantages and technical properties:

• Dedicated to thin materials (1–8 mm): The reduced spiral eliminates upward pulling forces, preventing the lifting of flimsy sheets.
• Single-edged Z1 construction (positive): The single cutting edge allows for efficient chip removal, minimizing friction and the risk of overheating the material.
• Polished chip flute: The mirror-like surface of the spiral prevents sticking and secondary welding of chips to the tool body.
• Finishing geometry of the blade: The precisely sharpened edge guarantees perfect edge quality without fraying.
• Low grip roughness (Ra ≤ 0.3 µm): The ground surface of the shank protects against slipping in the holder and shields the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Purpose and application range:

The tool is intended for cutting operations as well as edge bonding and trimming in thin plastic sheets on CNC machining centres.

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