Spiral router bit Finishing VHM Z2 D10 I32 L80 S10 RH positive

Ball-nose double-edged VHM spiral end mill, positive from the SI01 series – precise sculpting and 3D machining

Index: SI01.10.032.080.10R

Industrial ball-nose spiral end mill made from solid sintered carbide (VHM) from the SI01 series, with positive geometry (chip removal upwards). Designed for precise sculpting, 3D model machining, cutting, as well as welding and edge trimming on CNC machining centres and overhead spindle milling machines. The rounded front radius combined with finishing blade geometry (Z2) enables perfectly smooth and fluid surface transitions when machining bas-reliefs and 3D spatial forms. The right-hand helical flute efficiently evacuates chips upwards, protecting the cutting zone from overheating. The ground shank with H6 accuracy class eliminates radial run-out, protecting the drive system and ensuring high stability of the process.

Design advantages and technical properties:

• Double-edged Z2 ball-nose design (positive): The rounded front profile enables precise contour milling, bas-relief sculpting, and 3D spatial modelling.
• Positive design with upward chip removal: The right-hand spiral efficiently evacuates chips from deep grooves and 3D spaces, ensuring a clean lower edge of the material being machined.
• Finishing blade geometry: Precisely sharpened cutting edges guarantee a high standard of surface finishing without the need for manual grinding.
• Monolithic sintered carbide (VHM): The rigid monolithic structure reduces tool deflection under load and maintains dimensional precision.
• Low shank roughness (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle's taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures stability and quiet operation at maximum rotational speeds.

Intended use and application range:

The tool is intended for 3D model milling operations, sculpting, cutting, as well as welding and edge trimming on CNC machines.

It performs excellently in machining materials such as: softwood and hardwood, raw MDF boards, raw chipboards, and plywood.
