Three-flute VHM spiral end mill for aluminium and plastics with upward chip removal – clean bottom edge

Index: SR01.16.055.110.16R

Industrial three-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip removal). The three cutting edge arrangement (Z3) ensures higher body rigidity and allows for significantly higher feed rates compared to two-flute tools. The right-hand screw line efficiently removes chips upwards, guaranteeing a clean and tear-free bottom edge. Designed for highly efficient cutting, as well as edge chamfering and alignment in aluminium, plastics, and composites on CNC machining centres and overhead milling machines. The finishing cutting edge geometry combined with polished chip grooves prevents chips from sticking to the tool body. The ground shank in H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Construction advantages and technical properties:

• Three-flute Z3 construction (positive): Three cutting edges allow for a significant increase in feed speed while maintaining smooth cutting and high surface finish quality.
• Positive geometry (upward chip removal): The right-hand spiral lifts chips upwards, effectively preventing fraying and tearing on the underside of the workpiece.
• Polished chip grooves: The mirror-like surface of the spiral reduces friction and prevents chips from welding to the tool body.
• Finishing edge geometry: Precise finishing of the cutting edges ensures a smooth surface after machining.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid material guarantees long tool life and dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in G2.5 class: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

This tool is intended for cutting, as well as edge chamfering and alignment in aluminium, plastics, and composite materials on CNC machining centres.

Used for machining materials such as aluminium, plastics, and composites like CORIAN® and HPL.
