Multi-blade spiral cutter VHM for composites with downward chip removal – clean top edge and delamination protection

Index: CVS.03.010.060.06R

Industrial multi-blade spiral cutter made from a solid piece of sintered carbide (VHM) with negative geometry (downward chip removal). The specialist multi-edge design is intended for machining composite materials, eliminating the risk of structure delamination and pulling out glass and carbon fibres. The left-hand spiral fluting directs the cutting forces and chip downwards, which presses the workpiece against the table and guarantees a clean, tear-free top edge. Designed for precise cutting, bonding, grooving, and milling of composites on CNC machining centres and overhead spindle milling machines. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the machine's drive system.

Structural advantages and technical properties:

• Multi-blade geometry for composites: The multi-edge cutting system cleanly shears the material structure, effectively preventing delamination and pulling out glass and carbon fibres.
• Negative geometry (downward chip removal): The left-hand chip fluting directs the chips downwards and presses the workpiece against the base, ensuring a clean finish on the upper edge of the detail.
• Sintered carbide (VHM) monolith: The rigid and abrasion-resistant structure of the monolith ensures high tool longevity when machining highly abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing to 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, bonding, grooving, and milling operations on composite materials at CNC machining centres.

Used in the machining of materials such as carbon fibre reinforced plastics (CFRP), glass fibre reinforced plastics (GFRP), as well as CORIAN® and HPL composites.
