Router bit for composites Roughing D16 I45 L100 S16 RH

Multi-edge spiral end mill VHM composite roughing cutter – rosette front (CNR) and machining without delamination

Index: CNR.16.045.100.16R

Industrial roughing end mill made from solid cemented carbide (VHM) with a rosette-type front (CNR) and neutral blade 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 delamination of composites and pulling out 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. Dedicated to efficient cutting, grooving, and bonding on CNC machining centres. The ground shank in H6 class protects the spindle from vibrations and prevents radial run-out.

Design advantages and technical properties:

• Rosette front geometry (CNR): The dedicated front design reduces resistance during axial immersion, allowing stable entry into the material.
• Multi-edge roughing system: The dense tooth design finely crushes chips, preventing layer separation and edge fraying.
• 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.
• Monolithic cemented carbide (VHM): High hardness and wear resistance ensure a longer service life 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 allows for safe and vibration-free operation at very high speeds.

Purpose and scope of application:

The tool is intended for rough cutting operations, entry into the material along the Z-axis, cutting and bonding 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.
