Spiral router bit Semi-finishing / Roughing-Finishing VHM Z4 D16 I35 L90 S16 RH positive

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

Index: SH01.16.035.090.16R

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

Design advantages and technical properties:

• Four-flute Z4 (positive) design: Four spiral flutes with upward chip removal ensure efficiency and a clean finish on the lower edge of the machined part.
• Hybrid geometry (finishing-roughing): The blade profile allows for simultaneous excess material removal and achieving a finished surface after machining.
• Solid carbide (VHM): The rigid monolithic construction reduces tool deflections 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 cone from wear.
• Dynamic balancing class G2.5: Balancing in accordance with ISO standards guarantees stable operation without vibrations at high speeds.

Intended use and scope of application:

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

It works excellently for machining soft and hard solid wood, raw MDF boards, raw particle boards, and plywood.
