Two-edged VHM spiral end mill with a conical-spherical shape for reliefs and 3D models – maximum stiffness and 3D detail

Index: SQ29.02.080.120.12R

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

Construction advantages and technical properties:

• Z2 conical-spherical design (positive): The combination of conical body and spherical front ensures tool stiffness, allowing for deep and precise 3D machining without the risk of cutter deflection.
• Positive design with upward chip removal: The right-hand spiral effectively evacuates chips from deep details and grooves, guaranteeing cleanliness in the cutting zone.
• Finishing cutting edge geometry: Precisely ground cutting edges allow for high smoothness of sculpted surfaces without the need for manual finishing.
• Sintered carbide monolith (VHM): The rigid monolithic structure ensures resistance to abrasive wear and enables prolonged operation on complex 3D projects.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank eliminates the risk of slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balance in class G2.5: Balancing according to ISO standards ensures vibration-free and quiet operation at maximum rotational speeds.

Intended use and application range:

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

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