Three-flute VHM spiral end mill for aluminium and plastics with upward chip ejection – high performance roughing

Index: SR33.08.032.070.08R

Industrial three-flute spiral end mill made from monolithic carbide with a roughing geometry and upward chip ejection. Designed for demanding cutting operations and efficient removal of large material excesses in aluminium, plastics, and composites. The specially profiled cutting edge crushes the material into smaller pieces, which reduces cutting resistance, prevents clogging of channels, and decreases spindle load. The arrangement of three cutting edges combined with a right-handed helical design provides higher tool rigidity and efficiently removes chips from the underside of the material. The ground shank in class H6 accuracy 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 pieces, reducing cutting resistance and preventing entrapment of the material.
• Three-flute Z3 design: Three cutting edges allow for increased feed rate while maintaining smooth operation and high body rigidity.
• Positive geometry: Right-handed spiral lifts the chips 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.
• Monolithic carbide (VHM): The rigid and wear-resistant structure of the monolith guarantees 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 taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards ensures vibration-free operation at very high rotations.

Intended use and application range:

The tool is designed 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 composites like CORIAN® and HPL.
