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

Index: ST01.08.022.060.08R

Industrial single-edged spiral cutter made of solid carbide (VHM) with positive geometry (upward chip removal). Designed for precise cutting, edging, and aligning edges in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The finishing geometry with one cutting edge (Z1) combined with a polished flute effectively prevents the workpiece material from sticking and melting. The right-hand screw design efficiently removes chips upwards, protecting the cutting zone from overheating and ensuring a smooth edge without the need for additional polishing. The ground shank in accuracy class H6 eliminates radial run-out, protecting the machine's drive system.

Design advantages and technical properties:

• Single-edge design Z1 (positive): The single cutting edge enables quick removal of large amounts of material, minimising friction and the risk of overheating the plastic.
• Polished flute: The mirror-like surface of the spiral prevents the adherence and secondary welding of chips to the tool body.
• Finishing geometry of the blade: Precisely ground edge ensures cleanliness and smoothness of the cut edge.
• Solid carbide (VHM): The rigid VHM construction reduces vibrations and maintains dimensional accuracy.
• Low roughness of the shank (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high rotational speeds.

Intended use and application range:

The tool is designed for cutting, edging, and aligning edges in plastics on CNC machining centres.

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