Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D20 I60 L120 S20 RH positive

Four-blade spiral end mill VHM finishing-heavy series SH01 – high efficiency and machining precision

Index: SH01.20.060.120.20R

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

Design advantages and technical properties:

• Four-blade Z4 design (positive): Four spiral blades with chip ejection upwards guarantee efficiency and a clean finish on the lower edge of the machined part.
• Hybrid geometry (finishing-heavy): The blade profile allows for simultaneous excess removal and achieving a finished surface after cutting.
• Solid carbide (VHM): Rigid monolithic construction reduces tool deflection under load and maintains dimensional precision.
• Low grip 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 compliant with ISO standards guarantees stable operation without vibration at high speeds.

Intended use and application range:

The tool is intended for cutting and joining and aligning edges on CNC machining centres and overhead milling machines.

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