Router bit for composites Roughing D6 I15 L60 S6 RH

Multi-edge spiral end mill VHM for composites – rosette head (CNR) and machining without delamination

Index: CNR.06.015.060.06R

Industrial roughing end mill made from solid sintered carbide (VHM) with a rosette-type head (CNR) and neutral cutter geometry (chip ejection to the sides). The head 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 layout breaks up the material, preventing delamination of composites and pulling of glass and carbon fibres. The neutral cutting direction does not generate axial forces (either pushing or lifting), ensuring a high standard of edge finish on both sides of the plate. Designed for efficient scribing, grooving and bonding on CNC machining centres. The ground shank in class H6 secures the spindle against vibrations and prevents radial runout.

Design advantages and technical properties:

• Rosette head geometry (CNR): The dedicated head layout reduces resistance during axial immersion, allowing stable entry into the material.
• Multi-edge roughing layout: Dense tooth design finely crushes chips, preventing layer separation and fraying of edges.
• Neutral chip ejection to the sides: The absence of pressure and lifting of the part guarantees stable cutting and a clean two-sided profile.
• Monolith of sintered carbide (VHM): High hardness and wear resistance ensure a longer lifespan 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 intended for rough cutting operations, entering the material along the Z-axis, scribing and bonding in composites and plywood on CNC machines.

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