Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D12 I32 L70 S12 RH positive

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

Index: SH01.12.032.070.12R

Industrial spiral end mill made of solid carbide (VHM) from the SH01 series with a positive construction (chip removal upwards). Designed for efficient cutting as well as jointing and trimming edges of wood and wood-based materials on CNC machining centres and overhead spindle milling machines. The tool features a geometry that combines the advantages of roughing and finishing machining using four spiral flutes (Z4). This ensures high cutting efficiency, a smooth finish on the lower edge of the workpiece, and smooth operation at high feed rates. The ground shank in H6 accuracy class eliminates radial runout, preventing vibrations and protecting the machine's spindle.

Construction advantages and technical properties:

• Four-flute Z4 (positive) construction: Four spiral flutes with upward chip removal guarantee efficiency and a clean finish on the lower edge of the workpiece.
• Hybrid geometry (finishing-roughing): The flute profile allows for simultaneous excess removal and achieving a finished surface after cutting.
• Monolithic carbide (VHM): Rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• Low shank 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 in accordance with ISO standards ensures stable operation without vibration at high speeds.

Application and scope of use:

The tool is intended for cutting operations as well as jointing and trimming edges on CNC machining centres and overhead spindle milling machines.

It performs excellently in machining soft and hard solid wood, raw MDF boards, raw chipboards, and plywood.
