Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D12 I42 L90 S12 RH positive

Four-flute end mill VHM finishing-roughing from the SH01 series – high efficiency and precision machining

Index: SH01.12.042.090.12R

Industrial spiral end mill made of solid carbide (VHM) from the SH01 series with a positive design (chip removal upwards). Designed for efficient cutting and edge jointing and levelling of wood and wood-based materials on CNC machining centres and overhead spindle milling machines. The tool features a geometry combining the advantages of roughing and finishing machining and the use of four spiral flutes (Z4). This ensures high cutting efficiency, a smooth finish on the bottom edge of the machined material, and smooth operation at high feed rates. The ground shank in accuracy class H6 eliminates radial run-out, preventing vibrations and protecting the machine's spindle motor.

Design advantages and technical properties:

• Four-flute design Z4 (positive): Four spiral flutes with upward chip removal guarantee efficiency and a clean finish on the bottom edge of the machined part.
• Hybrid geometry (finishing-roughing): The profile of the blades allows for simultaneous excess material removal and achieving a finished surface after machining.
• Solid carbide (VHM): Rigid monolithic construction reduces tool deflection under load and allows for dimensional precision.
• Low grip roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle cone from wear.
• Dynamic balancing in class G2.5: Balancing according to ISO standards ensures stable operation without vibration at high speeds.

Intended use and application range:

The tool is designed for cutting operations and edge jointing and levelling on CNC machining centres and overhead spindle milling machines.

It performs excellently in the machining of solid soft and hard wood, raw MDF board, raw particle board, and plywood.
