Single-edged spiral cutter VHM for PLEXI with upward chip removal

Index: ST01.12.035.080.12R

Industrial single-edged spiral cutter made from solid carbide (VHM) with positive geometry (upward chip removal). Designed for precise cutting, joining, and edge trimming in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The finishing geometry with a single blade (Z1) combined with a polished flute effectively prevents sticking and melting of the work material. The right-hand helical fluting efficiently removes chips upwards, protecting the cutting zone from overheating and providing a smooth edge without the need for additional polishing. The ground shank in class H6 eliminates radial runout, protecting the machine's drive system.

Structural advantages and technical properties:

• Single-edged Z1 (positive) design: The single cutting edge allows for rapid removal of a large amount of material, minimizing friction and the risk of overheating the material.
• Polished flute: The mirror-like surface of the spiral prevents sticking and secondary welding of chips to the tool body.
• Finishing blade geometry: Precisely sharpened edge ensures cleanliness and smoothness of the edge after cutting.
• Solid carbide (VHM): The rigid structure of VHM reduces vibrations and maintains dimensional precision.
• 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 to class G2.5: Balancing compliant with ISO standards guarantees vibration-free operation at very high rotational speeds.

Intended use and application range:

The tool is intended for cutting operations as well as joining and trimming edges in plastics on CNC machining centres.

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