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

Index: ST28.64.127.635.64R

Industrial single-flute spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal). The tool features a small helix angle, which effectively prevents lifting and vibrations of the processed material. It is ideal for precise cutting, edge joining and levelling of thin materials with a thickness from 1 mm to 8 mm on CNC machines and vertical milling machines. The finishing geometry with a single cutting edge (Z1) combined with a polished chip flute prevents sticking and melting of the chips. The ground shank with H6 accuracy eliminates radial runout, protecting the machine's drive system and ensuring machining stability.

Structural advantages and technical properties:

• Dedicated to thin materials (1–8 mm): Reduced spiral eliminates upward pulling forces, preventing the lifting of flexible sheets.
• Single-flute design Z1 (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 re-welding of the chips to the tool body.
• Finishing geometry of the blade: Precisely ground 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 G2.5 class: Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.

Purpose and scope of application:

The tool is designed for cutting, edge joining, and levelling edges in thin plastic sheets on CNC machining centres.

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