Tapered ball nose router bit for 3D reliefs VHM Z3 R3 D12 I85 L150 S12 RH Finishing positive

Two-flute VHM conical-ball end mill for relief carving and 3D models – maximum rigidity and 3D detail

Index: SQ29.12.085.150.12R

Industrial conical-ball end mill made of solid carbide (VHM) from the SQ29 series, with positive geometry (chip ejection upwards). Designed for precision machining of 3D models, performing deep 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 flutes (Z2) ensures tool rigidity at small working diameters, eliminating the risk of breakage and allowing the reproduction of fine 3D spatial details. The right-hand screw line efficiently evacuates chips upwards, protecting the cutting area from overheating. The ground shank in class H6 precision eliminates radial runout, protecting the drive system and ensuring stable operation without vibrations. 

Design advantages and technical properties:

• Conical-ball design Z2 (positive): The combination of a conical body and spherical tip ensures tool rigidity, allowing for deep and precise 3D machining without the risk of cutter deflection.
• Positive design with upward chip ejection: The right-hand screw line effectively evacuates chips from deep details and grooves, ensuring cleanliness in the cutting area.
• Finishing geometry of the blades: Precisely ground cutting edges allow for high smoothness of carved surfaces without the need for manual finishing.
• Monolithic tungsten carbide (VHM): The rigid monolithic construction guarantees wear resistance and allows for prolonged work 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 balancing in class G2.5: Balancing according to ISO standards ensures vibration-free and quiet operation at maximum rotational speeds.

Application and scope of use:

The tool is designed for precision milling of forms and 3D models, 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.
