Single-edged spiral cutter VHM for PLEXI with downward chip evacuation – ideal upper edge

Index: ST51.03.006.060.06R

Industrial single-edged spiral cutter made of solid carbide (VHM) with negative geometry (downward chip evacuation). Designed for precise cutting, edge bonding and alignment, grooving, and trenching in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The left-hand helical flutes grip the workpiece to the table and evacuate chips downwards, making it ideal for machining small parts and flexible sheets of material. Special finishing geometry with a single edge (Z1) combined with a polished flute effectively prevents adhesion and melting of the material, ensuring a perfectly finished upper surface edge. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Construction advantages and technical properties:

• Single-edged design Z1 (negative): The single cutting edge efficiently evacuates chips downwards, stabilising the material on the working table.
• Polished flute: The mirror-like surface of the flute counteracts material adhesion and secondary welding of chips to the body.
• Finishing cutter geometry: Precisely ground edge ensures perfect edge quality without fraying and damage on the upper surface.
• Solid carbide (VHM): High structural rigidity of VHM eliminates vibrations and allows for dimensional stability.
• Low shank roughness (Ra ≤ 0.3 µm): Ground surface of the shank protects the holder and spindle taper from wear and prevents slippage.
• Dynamic balancing class G2.5: Balancing compliant with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

The tool is intended for cutting, edge bonding and alignment, grooving, and trenching operations in plastics on CNC machining centres.

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