Three-flute VHM spiral cutter for aluminium and plastics with upward chip ejection – high roughing machining efficiency

Index: SR33.06.022.060.06R

Industrial three-flute spiral cutter made from solid carbide with roughing geometry and upward chip ejection. Designed for demanding grooving operations and efficient removal of large excess material in aluminium, plastics, and composites. The specially profiled cutting edge breaks the material into smaller pieces, reducing cutting resistance, preventing clogging of channels, and reducing spindle load. The arrangement of three cutting edges combined with a right-hand screw line ensures higher tool rigidity and effectively removes chips from below the material. The ground shank in accuracy class H6 eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Roughing geometry with chip breaker: The profiled teeth break the chip into small elements, reducing cutting resistance and preventing material jamming.
• Three-flute Z3 construction: Three cutting edges allow for increased feed rates while maintaining smooth operation and high rigidity of the body.
• Positive geometry: The right-hand spiral lifts the chips upwards, protecting the lower edge of the workpiece from damage.
• Polished chip grooves: The mirror-finish surface of the spiral reduces friction and prevents material from sticking to the tool body.
• Sintered carbide monolith (VHM): The rigid and wear-resistant structure of the monolith ensures durability when working with large excesses.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

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

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