Two-edged spiral end mill VHM conical-spherical for bas-reliefs and 3D models – maximum rigidity and 3D detail

Index: SQ29.02.025.070.06R

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

Design advantages and technical properties:

• Conical-spherical Z2 (positive) design: The combination of the conical body and spherical tip provides tool rigidity, allowing for deep and precise 3D machining without the risk of tool deflection.
• Positive design with upward chip removal: The right-hand helical flute effectively evacuates chips from deep details and grooves, ensuring cleanliness of the cutting zone.
• Finishing edge geometry: Precisely ground cutting edges allow for high smoothness of sculpted surfaces without the need for manual finishing.
• Sintered carbide (VHM) monolith: The rigid monolithic design ensures resistance to abrasive wear and allows for long-term work on complex 3D projects.
• Low shank 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 class G2.5: Balancing in accordance 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, bas-reliefs, and spatial engraving on CNC machining centres.

It performs excellently in machining materials such as: solid soft and hard wood, raw MDF board, raw chipboard, plywood, as well as plastics and aluminium.
