Single-flute spiral end mill VHM for aluminium and plastics with upward chip removal – clean bottom edge and efficient chip evacuation

Index: SP02.06.022.080.08R

Industrial single-flute spiral end mill made from solid sintered carbide (VHM) with positive geometry and undercut (upward chip removal). The undercut body design facilitates penetration into the material, reduces overall friction surface, and ensures optimal chip flow, which eliminates the risk of tool clogging during deep machining. The tool has a helix angle of 30° and a polished chip flute, guaranteeing edge finishing. Dedicated to efficient cutting, grooving, and edging in aluminium, ALU/PVC profiles, plastics, and composites on CNC machining centres and overhead spindle mills. The use of a special grade of carbide extends tool life, while the ability to apply protective coatings reduces friction and improves work efficiency. The ground shank in H6 accuracy class eliminates radial runout, protecting the machine's drive system.

Design advantages and technical properties:

• Single-flute Z1 design with undercut (positive): Special undercut body facilitates entry into the material along the Z-axis, reduces tool heating, and decreases cutting resistance during deep passes.
• Helix angle of 30° and polished flute: Precise 30° helix angle combined with polished flute surface eliminates chip welding and promotes smooth upward chip evacuation.
• Special grade of carbide (VHM): Enhanced wear resistance provides long tool life during machining of non-ferrous metals and plastics.
• Option for protective coatings: Design adapted for the application of protective coatings that reduce temperature in the cutting zone.
• Low shank roughness (Ra ≤ 0.3 µm): Ground shank surface prevents slippage in the holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures vibration-free operation at very high rotational speeds.

Application and scope of use:

The tool is intended for cutting, grooving, and edging operations in aluminium and profiles on CNC machining centres.

Used in the machining of materials such as: aluminium, aluminium profiles and PVC, ALUCOBOND® plates, ALUCOBOND® A2, and plastics.
