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

Index: ST51.04.008.060.04R

Industrial single-edged spiral milling cutter made of solid carbide (VHM) with a negative geometry (downward chip removal). Designed for precise cutting, edging, and aligning edges, grooving, and grooving in plexiglass, plastics, and composites on CNC machines and vertical milling machines. The left-hand screw line presses the workpiece to the table and removes the chips downwards, which is ideal for machining small parts and flexible plastic sheets. The special finishing geometry with one blade (Z1) combined with a polished chip flute effectively prevents material sticking and melting, ensuring a perfectly finished edge on the upper surface. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Single-edged Z1 design (negative): The single cutting blade efficiently removes chips downwards, stabilising the material on the operational table.
• Polished chip flute: The mirror surface of the spiral counteracts sticking and secondary welding of chips to the body.
• Finishing blade geometry: Precisely sharpened edge ensures perfect edge quality without fraying and damage on the upper surface.
• Solid carbide (VHM): High structural rigidity of VHM eliminates vibrations and maintains 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 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 intended for cutting, edging, and aligning edges, grooving, and grooving in plastics on CNC machining centres.

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