Router bit for composites Roughing D6 I30 L70 S6 RH

Multi-edge spiral end mill VHM composite roughing – rosette face (CNR) and delamination-free machining

Index: CNR.06.030.070.06R

Industrial roughing mill made from solid carbide (VHM) with a rosette type face (CNR) and neutral cutting geometry (chip ejection to the sides). The front construction facilitates axial entry into the material along the Z-axis, reducing cutting resistance and eliminating the risk of structural damage upon entry. The multi-edge cutting system crushes the material, preventing the delamination of composites and the pulling out of glass and carbon fibres. The neutral cutting direction does not generate axial forces (either compressive or lifting), ensuring a high standard of edge finish on both sides of the plate. Designed for efficient cutting, grooving, and jointing on CNC machining centres. Ground H6 shank secures the spindle against vibrations and prevents radial runout.

Design advantages and technical properties:

• Rosette face geometry (CNR): The dedicated face design reduces resistance during axial plunging, enabling stable entry into the material.
• Multi-edge roughing system: Dense teeth finely crush chips, preventing layer separation and edge fraying.
• Neutral chip ejection to the sides: Absence of pressure and lifting on the workpiece guarantees stable cutting and a clean profile on both sides.
• Solid 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 taper from wear.
• Dynamic balancing G2.5: Compliance with ISO standards enables safe and vibration-free operation at very high speeds.

Intended use and area of application:

The tool is intended 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 reinforced plastics (GFRP), CORIAN® composite panels, HPL laminates, and plywood.
