Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D8 I32 L70 S8 RH positive

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

Index: SH01.08.032.070.08R

Industrial spiral end mill made from solid carbide (VHM) from the SH01 series with a positive design (chip removal upward). Designed for efficient cutting, jointing, and edging 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, with the use of four spiral blades (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 accuracy class H6 eliminates radial runout, preventing vibrations and protecting the machine’s electro-spindle.

Structural advantages and technical properties:

• Four-blade Z4 design (positive): Four spiral blades with upward chip removal guarantee efficiency and a clean finish on the lower edge of the machined element.
• Hybrid geometry (finishing-roughing): The blade profile allows for simultaneous excess material removal and a finished surface after cutting.
• Solid carbide (VHM): The rigid monolithic structure reduces tool deflection under load and maintains dimensional precision.
• Low grip roughness (Ra ≤ 0.3 µm): The ground grip 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 vibrations at high speeds.

Intended use and scope of application:

The tool is intended for cutting, jointing, and edging operations on CNC machining centres and overhead spindle milling machines.

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