Three-flute VHM spiral mill for aluminium and plastics with upward chip removal – high efficiency rough machining

Index: SR33.20.032.080.20R

Industrial three-flute spiral mill made from sintered carbide with roughing geometry and upward chip removal. 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 decreasing spindle load. The arrangement of the three cutting edges combined with the right-hand screw helix ensures higher tool rigidity and effectively removes chips from the bottom of 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 chip into small elements, reducing cutting resistance and preventing the clogging of machined material.
• Three-flute Z3 construction: Three cutting edges allow for increased feed speed while maintaining smooth operation and high rigidity of the body.
• Positive geometry: The right-hand spiral lifts the chips upwards, protecting the underside of the machined material from damage.
• Polished chip grooves: The mirrored surface of the spiral reduces friction and prevents chips from sticking to the tool body.
• Sintered carbide monolith (VHM): The rigid and wear-resistant structure of the monolith guarantees 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 in accordance with ISO standards ensures vibration-free operation at very high speeds.

Purpose and range of application:

The tool is designed for rough cutting, shaping, 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.
