Router bit for composites Roughing D8 I35 L80 S8 RH

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

Index: CNR.08.035.080.08R

Industrial roughing cutter made of sintered carbide (VHM) with a rosette type face (CNR) and neutral cutting edge geometry (chip removal to the sides). The face design facilitates axial entry into the material along the Z-axis, reducing cutting resistance and eliminating the risk of structure damage upon entry. The multi-edge cutting system breaks up the material, preventing delamination of composites and the pulling of glass and carbon fibres. The neutral cutting direction does not create axial forces (either pressing or lifting), ensuring a high standard of edge finishing on both sides of the plate. Dedicated to efficient cutting, grooving, and bonding on CNC machining centres. The ground shank in class H6 protects the spindle from vibrations and prevents radial runout.

Design advantages and technical properties:

• Rosette face geometry (CNR): The dedicated face configuration reduces resistance during axial immersion, allowing for stable entry into the material.
• Multi-edge roughing system: The dense tooth pattern finely crushes chips, preventing layer separation and edge fraying.
• Neutral chip removal to the sides: The absence of pressure and lifting of the workpiece ensures stable cutting and a clean profile on both sides.
• Sintered carbide (VHM): High hardness and wear resistance ensure a longer lifespan 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 allows for safe and vibration-free operation at very high speeds.

Purpose and range of application:

The tool is intended for rough cutting operations, Z-axis entry into the material, cutting, and bonding in composites and plywood on CNC machines.

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