Router bit for composites Roughing D10 I35 L80 S10 RH

Multi-edge spiral milling cutter VHM for composites – rosette front (CNR) and machining without delamination

Index: CNR.10.035.080.10R

Industrial roughing cutter made from solid carbide (VHM) with a rosette-type front (CNR) and neutral cutting edge geometry (chip removal to the sides). The front design facilitates axial entry into the material along the Z-axis, reducing cutting resistance and eliminating the risk of damaging the structure upon entry. The multi-edge cutting arrangement breaks down the material, preventing delamination of composites and pulling out of glass and carbon fibres. The neutral cutting direction does not generate axial forces (neither pushing nor lifting), ensuring a high standard of edge finishing on both sides of the plate. Dedicated to efficient cutting, grooving, and jointing on CNC machining centres. The ground shank in class H6 protects the spindle from vibrations and prevents radial run-out.

Design advantages and technical properties:

• Rosette front geometry (CNR): The dedicated front arrangement reduces resistance during axial plunging, allowing stable entry into the material.
• Roughing multi-edge arrangement: Dense tooth geometry finely breaks chips, preventing layers from separating and edge fraying.
• Neutral chip removal to the sides: The absence of pressure and lifting of the workpiece guarantees stable machining and a clean profile on both sides.
• Solid carbide (VHM): High hardness and wear resistance ensure longer tool life when machining abrasive materials.
• Low shank roughness (Ra ≤ 0.3 µm): Precisely ground shank prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing G2.5: Compliance with ISO standards enables safe and vibration-free operation at very high speeds.

Intended use and application range:

The tool is designed for rough cutting operations, axial entry into the material along the Z-axis, cutting, and jointing in composites and plywood on CNC machines.

Used for machining materials such as: carbon fibre reinforced plastics (CFRP), glass fibre (GFRP), CORIAN® composite boards, HPL laminates, and plywood.
