Single-edge spiral milling cutter VHM for PLEXI with downward chip removal – ideal upper edge

Index: ST51.04.008.060.06R

Industrial single-edge spiral cutter made from solid carbide (VHM) with negative geometry (downward chip removal). Designed for precise cutting, bonding, and edge trimming, grooving, and slotting in plexiglass, plastics, and composites on CNC machines and vertical spindle milling machines. The left-handed screw line presses the workpiece against the table and directs the chips downwards, which is particularly effective for machining small parts and thin sheets of material. The special finishing geometry with a single blade (Z1) combined with a polished chip groove effectively prevents material sticking and melting, ensuring a perfectly finished edge on the upper surface. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Single-edge design Z1 (negative): The single cutting blade effectively directs the chips downwards, stabilising the material on the working table.
• Polished chip groove: The mirror-like surface of the spiral counteracts sticking and secondary welding of chips with the body.
• Finishing blade geometry: The precisely sharpened edge ensures perfect edge quality without fraying or damage to 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): The ground surface of the shank protects the holder and spindle cone from wear and prevents slipping.
• Dynamic balancing class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high speeds.

Intended use and applications:

Tool designed for cutting, bonding, and edge trimming, grooving, and slotting in plastics on CNC machining centres.

Used in the processing of materials such as: PLEXI (acrylic), plastics, ALUCOBOND® panels, ALUCOBOND® A2, and composites like CORIAN® and HPL.
