Spiral router bit Finishing VHM Z2 D8 I32 L80 S8 RH positive

Two-edged spiral mill VHM ball nose, positive from the SI01 series – precise carving and 3D machining

Index: SI01.08.032.080.08R

Industrial ball nose spiral mill made of solid carbide (VHM) from the SI01 series, with positive geometry (chip removal upwards). Designed for precise carving, 3D model machining, cutting, as well as welding and edge leveling on CNC machining centres and overhead spindle milling machines. The spherical front radius combined with the finishing geometry of the cutting edges (Z2) allows for perfectly smooth, fluid surface transitions when machining bas-reliefs and three-dimensional forms. 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 high process stability.

Structural advantages and technical properties:

• Two-edged Z2 (positive) ball nose design: The rounded front profile enables precise contour milling, carving bas-reliefs, and three-dimensional modelling.
• Positive design with upward chip evacuation: The right-hand helix efficiently removes chips from deep grooves and 3D spaces, ensuring a clean lower edge of the machined material.
• Finishing geometry of the cutting edges: Precisely sharpened cutting edges guarantee a high standard of surface finishing without the need for manual grinding.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflection under load and allows for dimensional precision.
• Low roughness of the shank (Ra ≤ 0.3 µm): The ground surface of the shank prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards guarantees stability and quiet operation at maximum rotational speeds.

Intended use and application range:

The tool is intended for operations such as milling 3D models, carving, cutting, as well as welding and edge leveling on CNC machines.

It excels in machining materials such as: solid soft and hard wood, raw MDF board, raw particle board, and plywood.
