Router bit for composites Roughing D3 I10 L60 S6 RH

Multi-edge spiral end mill VHM for composite materials – rosette head (CNR) and delamination-free machining

Index: CNR.03.010.060.06R

Industrial roughing mill made of solid carbide (VHM) with a rosette type head (CNR) and neutral geometry of the cutting edges (chip ejection to the sides). The design of the head 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 chips, preventing the delamination of composites and the pulling of glass and carbon fibres. The neutral cutting direction does not generate axial forces (either pushing or lifting), ensuring a high quality finish on both sides of the plate. Dedicated to efficient grooving, notching, and joining 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 design reduces resistance when plunging axially, allowing for stable entry into the material.
• Roughing multi-edge system: Dense teeth finely crush the chips, preventing the layers from separating and the edges from fraying.
• Neutral chip ejection to the sides: The absence of pressure and lifting of the workpiece guarantees stable machining and a clean profile on both sides.
• Solid carbide (VHM): High hardness and wear resistance ensure longer tool life when machining abrasive materials.
• Low surface roughness of the shank (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 range of applications:

The tool is designed for rough cutting operations, axial entry into the material along the Z axis, grooving, and joining in composites and plywood on CNC machines.

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