Spiral router bit Finishing VHM Z2 D12 I35 L80 S12 RH positive

Two-flute spiral end mill VHM ball nose, positive from the SI01 series – precision carving and 3D machining

Index: SI01.12.035.080.12R

Industrial ball nose spiral end 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 edge welding and alignment on CNC machining centres and overhead milling machines. The ball nose end combined with finishing blade geometry (Z2) enables achieving perfectly smooth, fluid surface transitions when machining reliefs and 3D spatial forms. The right-hand spiral efficiently evacuates chips upwards, protecting the cutting zone from overheating. The ground shank in accuracy class H6 eliminates radial runout, safeguarding the drive system and ensuring high stability of the process.

Design advantages and technical properties:

• Two-flute ball nose Z2 (positive) design: The rounded leading edge profile allows for precise contour milling, relief carving, and 3D spatial modelling.
• Positive design with upwards chip evacuation: The right-hand spiral efficiently evacuates chips from deep grooves and 3D spaces, ensuring a clean bottom edge of the work material.
• Finishing blade geometry: Precisely ground cutting edges guarantee a high standard of surface finish without the need for manual sharpening.
• Solid carbide (VHM): The rigid monolithic construction 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 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 designed for operations such as milling 3D models, carving, cutting, as well as edge welding and alignment on CNC machines.

It performs excellently in machining materials such as: soft and hard solid wood, raw MDF boards, raw particle boards, and plywood.
