Single-flute VHM spiral end mill for PLEXI with downward chip removal – ideal upper edge

Index: ST51.03.006.060.06RE

Industrial single-flute spiral end mill made from solid sintered carbide (VHM) with negative geometry (downward chip removal). Designed for precise cutting, edging, and machining edges, grooves, and slots in plexiglass, plastics, and composites on CNC machines and overhead milling machines. The left-handed screw line presses the workpiece against the table and removes the chips downwards, making it ideal for machining small parts and flexible sheets of material. The specially designed finishing geometry with a single cutting edge (Z1) combined with a polished chip flute effectively prevents material sticking and melting, ensuring a perfectly finished upper surface edge. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Construction advantages and technical properties:

• Single cutter design Z1 (negative): The single cutting edge efficiently removes chips downward, stabilising the material on the working table.
• Polished chip flute: The mirror-like surface of the spiral prevents chips from sticking and welding back to the body.
• Finishing cutter geometry: Precisely ground edge ensures perfect edge quality without fraying and damage on the upper surface.
• Solid sintered carbide (VHM): High structural rigidity of VHM eliminates vibrations and maintains dimensional stability.
• Low grip roughness (Ra ≤ 0.3 µm): The ground shank surface protects the holder and spindle cone from wear and prevents slipping.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

The tool is designed for cutting, edging, and machining edges, as well as grooving and slotting in plastics on CNC machining centres.

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