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

Index: ST28.03.012.060.06R

Industrial single-flute spiral cutter made from solid sintered carbide (VHM) with positive geometry (upward chip ejection). The tool is equipped with a small helix angle, effectively preventing lifting and vibrations of the machined material. It performs excellently for precision cutting as well as for edge jointing and aligning thin materials ranging from 1 mm to 8 mm thick on CNC machines and router milling machines. The finishing geometry with a single blade (Z1) combined with the polished chip flute prevents sticking and melting of the chips. The ground shank in H6 accuracy class eliminates radial runout, protecting the machine's drive system and ensuring stability during machining.

Design 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 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 surface of the spiral prevents sticking and secondary welding of the chips to the tool body.
• Finishing blade 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 range of application:

The tool is designed for cutting operations, as well as for edge jointing and aligning in thin sheets of plastic on CNC machining centres.

Used for machining materials such as: PLEXI (acrylic), plastics, ALUCOBOND® sheets, ALUCOBOND® A2, and composites such as CORIAN® and HPL.
