Router bit for composites Roughing D4 I22 L60 S6 RH

Multi-edge VHM spiral milling cutter composite roughing tool – rosette head (CNR) and delamination-free machining

Index: CNR.04.022.060.06R

Industrial roughing cutter made of solid carbide (VHM) with a rosette-type head (CNR) and neutral cutting edge geometry (chip ejection 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 system crushes the material, preventing delamination of composites and pulling out glass and carbon fibers. The neutral cutting direction does not generate axial forces (either pressing or lifting), ensuring a high standard of edge finish on both sides of the plate. Dedicated for efficient slicing, grooving, and jointing on CNC machining centres. The ground shank in H6 class protects the spindle from vibrations and prevents radial runout.

Design advantages and technical properties:

• Rosette head geometry (CNR): The dedicated front design lowers resistance during axial lowering, allowing for stable entry into the material.
• Multi-edge roughing system: Dense teeth finely crush chips, preventing separation of layers and fraying of edges.
• Neutral chip ejection to the sides: The absence of pressure and lifting of the workpiece guarantees stable cutting and a clean profile on both sides.
• Solid carbide (VHM): High hardness and wear resistance ensure longer tool life when machining abrasive materials.
• Low roughness of the shank (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, slicing, and jointing 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 boards, HPL laminates, and plywood.
