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

Index: SQ01.20.045.090.20R

Industrial two-flute spiral end mill made of solid carbide (VHM) with positive geometry (upward chip ejection). The arrangement of two cutting edges (Z2) ensures higher tool rigidity, reduced vibration, and the possibility of using higher feed rates while maintaining stability. The right-hand spiral effectively lifts the chips upwards, guaranteeing cleanliness and preventing tear-outs on the bottom edge of the workpiece. Dedicated to precise cutting, welding, and edge trimming in aluminium, plastics, and composite materials on CNC machining centres and vertical milling machines. The finishing geometry combined with polished chip grooves prevents chip adhesion to the body. The ground shank with H6 accuracy class eliminates radial run-out, protecting the machine spindle.

Construction advantages and technical properties:

• Two-flute Z2 (positive) design: Two cutting edges increase the rigidity of the mill and allow for increased feed speed with very smooth guidance in the material.
• Positive geometry (upward chip ejection): The right-hand spiral directs the chips upwards, preventing fraying and tear-outs on the underside of the machined plate.
• Polished chip grooves: The mirror-like surface of the spiral reduces friction, effectively preventing chips from sticking and welding to the body.
• Finishing blade geometry: Precisely ground cutting edges ensure a smooth finish on the machined surfaces.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid carbide reduces vibrations and helps maintain dimensional precision.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees vibration-free operation at very high speeds.

Application and usage range:

The tool is intended for cutting operations as well as welding and edge trimming in aluminium, plastics, and composites on CNC machining centres.

Used in the machining of materials such as: aluminium, plastics, and composites like CORIAN® and HPL.
