Ball nose spiral router bit with neck for 3D reliefs VHM Z3 D20 I40 L250 S20 RH Finishing positive

Two-edged spiral ball mill VHM from the SQ32 series for 3D relief carving

Index: SQ32.20.040.250.20R

Industrial spiral ball mill made from solid sintered carbide VHM from the SQ32 series, with positive geometry (chip removal upwards). The tool features an extended body with a taper above the working part, designed for deep machining of 3D models, cutting, and joining and aligning edges on CNC machines. The polished surface of the flutes prevents the machined material from sticking and facilitates quick chip evacuation. The spherical front radius combined with the finishing geometry of two cutting edges (Z2) allows for smooth surfaces to be achieved. The ground shank with an accuracy class of H6 eliminates radial runout, protecting the drive system and ensuring a high level of machining stability.

Design advantages and technical properties:

• Extended body with taper: The special taper of the working part enables safe and precise work in deep cuts and 3D shapes without the risk of the body colliding with the material.
• Polished flutes: Advanced polishing of the flutes efficiently evacuates chips, prevents the adhered material and reduces cutting resistance.
• Spherical Z2 design with upward chip removal: The right-hand screw line ejects the chip upwards, ensuring cleanliness in the cutting zone and high surface quality.
• Finishing edge geometry: Precisely sharpened cutting edges allow for a clean edge finish without the need for additional machining.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank protects against slipping in the tool holder and safeguards the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards ensures quiet and stable operation at high rotational speeds.

Purpose and range of use:

The tool is designed for precise machining of molds and 3D models, cutting, and joining and aligning edges on CNC machining centres.

It works excellently when machining materials such as: aluminium, CORIAN® composites, and HPL panels.
