Two-flute spiral cutter VHM for aluminium and plastics with upward chip eject – clean bottom edge

Index: SQ01.12.042.090.12R

Industrial two-flute spiral cutter made from monolithic cemented carbide (VHM) with positive geometry (upward chip eject). The arrangement of two cutting edges (Z2) ensures higher tool rigidity, vibration reduction, and the ability to use higher feeds while maintaining stability. The right-hand spiral effectively lifts chips upwards, guaranteeing cleanliness and the absence of tearing on the bottom edge of the processed material. Designed for precise cutting as well as jointing and edge smoothing in aluminium, plastics, and composite materials on CNC machining centres and overhead milling machines. The finishing geometry combined with polished chip grooves prevents the accumulation of chips on the tool body. The ground shank in class H6 accuracy eliminates radial runout, protecting the machine spindle.

Structural advantages and technical properties:

• Two-flute design Z2 (positive): Two cutting edges increase the rigidity of the cutter and allow for higher feed speeds while maintaining smooth operation in the material.
• Positive geometry (upward chip eject): The right-hand spiral directs chips upwards, preventing fraying and tearing on the underside of the processed plate.
• Polished chip grooves: The mirror surface of the spiral reduces friction, effectively preventing chips from sticking and welding to the tool body.
• Finishing blade geometry: Precisely ground cutting edges ensure a smooth finish on the machined surfaces.
• Monolithic cemented carbide (VHM): The rigid and wear-resistant structure of the monolith reduces vibrations and allows for 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 in accordance with ISO standards ensures vibration-free operation at very high speeds.

Purpose and range of application:

The tool is designed for cutting operations as well as jointing and edge smoothing 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.
