Three-flute VHM spiral cutter for aluminium and plastics with upward chip discharge – high performance for rough machining

Index: SR33.25.035.080.20R

Industrial three-flute spiral cutter made from a solid carbide blank with rough machining geometry and upward chip discharge. Dedicated to demanding cutting operations and efficient removal of large material excess in aluminium, plastics, and composites. The specially profiled cutting edge grinds the material into smaller pieces, which reduces cutting resistance, prevents clogging of channels, and reduces spindle load. The arrangement of three cutting edges combined with a right-hand helical design ensures higher tool rigidity and efficiently removes chips from the underside of the material. The ground shank with H6 accuracy class eliminates radial runout, protecting the machine drive system.

Structural advantages and technical properties:

• Rough machining geometry with chip breaker: The profiled teeth crush the chip into smaller parts, reducing cutting resistance and preventing material jamming.
• Three-flute Z3 design: Three cutting edges allow for increased feed rates while maintaining smooth operation and high body rigidity.
• Positive geometry: The right-hand spiral lifts the chip upwards, protecting the lower edge of the workpiece from damage.
• Polished chip flutes: The mirror surface of the spiral reduces friction and prevents material from sticking to the tool body.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid ensures durability when working with large excesses.
• Low grip 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 class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high speeds.

Intended use and application range:

The tool is intended for rough cutting, splitting, and welding operations in aluminium, plastics, and composite materials on CNC machining centres.

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