Two-flute spiral end mill VHM tapered spherical for reliefs and 3D models – maximum stiffness and 3D detail

Index: SQ29.06.051.110.12R

Industrial tapered spherical spiral end mill made from solid carbide (VHM) from the SQ29 series, with positive geometry (chip removal upwards). Designed for precision machining of 3D models, performing deep reliefs, engraving and sculpting on CNC machining centres and overhead spindle milling machines. The tapered body design combined with a spherical end radius and two spiral flutes (Z2) ensures tool stiffness at small cutting diameters, eliminating the risk of breakage and allowing for the reproduction of fine 3D spatial details. The right-hand helical flute efficiently removes chips upwards, protecting the cutting zone from overheating. The ground shank in tolerance class H6 eliminates radial run-out, protecting the drive system and ensuring stable operation without vibration. 

Design strengths and technical properties:

• Tapered spherical design Z2 (positive): The combination of a tapered body and spherical end ensures tool stiffness, allowing for deep and precise 3D machining without the risk of tool deflection.
• Positive design with upward chip evacuation: The right-hand helical flute effectively evacuates chips from deep details and grooves, guaranteeing cleanliness in the cutting zone.
• Finishing geometry of the flutes: Precisely ground cutting edges allow for a high smoothness of the sculpted surfaces without the need for manual finishing.
• Solid carbide (VHM): The rigid monolithic construction guarantees resistance to abrasive wear and enables long-term operation on complex 3D projects.
• Low grip roughness (Ra ≤ 0.3 µm): The ground shank surface eliminates the risk of slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing compliant with ISO standards ensures vibration-free and quiet operation at maximum rotational speeds.

Purpose and scope of application:

The tool is intended for precise milling of forms and 3D models, reliefs and spatial engraving on CNC machining centres.

It performs excellently when machining materials such as: solid softwood and hardwood, raw MDF board, raw particle board, plywood, as well as plastics and aluminium.
