Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D16 I55 L110 S16 RH positive

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

Index: SH01.16.055.110.16R

Industrial spiral end mill made from solid tungsten carbide (VHM) from the SH01 series with a positive design (chip removal upwards). Designed for efficient cutting and edge jointing and leveling 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 operations and uses four spiral flutes (Z4). This provides high cutting efficiency, a smooth finish on the lower edge of the workpiece, and a smooth operation at high feed rates. The ground shank in accuracy class H6 eliminates radial runout, preventing vibrations and protecting the machine spindle.

Design advantages and technical properties:

• Four-flute design Z4 (positive): Four spiral flutes with upward chip evacuation guarantee efficiency and a clean finish on the lower edge of the workpiece.
• Hybrid geometry (finishing-roughing): The flute profile allows simultaneous excess material removal and achieving a finished surface after machining.
• Solid tungsten carbide (VHM): The rigid monolithic design reduces tool deflection under load and maintains dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slipping in the tool holder and protects the spindle taper from wear.
• Dynamic balancing 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, edge jointing, and leveling operations on CNC machining centres and overhead spindle milling machines.

It performs exceptionally well in machining soft and hard solid wood, raw MDF board, raw chipboard, and plywood.
