Three-flute VHM spiral end mill for aluminium and plastics with upward chip evacuation – high performance rough machining

Index: SR33.20.060.120.20R

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

Design advantages and technical properties:

• Roughing geometry with chip breaker: The profiled teeth break the chips into small pieces, reducing cutting resistance and preventing the workpiece from 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 chips upward, protecting the lower edge of the work material from damage.
• Polished chip grooves: The mirror-finish surface of the spiral reduces friction and prevents the chips from sticking to the tool body.
• Solid carbide (VHM): The rigid and wear-resistant structure of the solid material ensures durability when working with large allowances.
• 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 compliant with ISO standards guarantees vibration-free operation at very high speeds.

Intended use and application range:

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

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