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

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

Index: SH01.16.055.110.16XR

Industrial spiral cutter made from solid carbide (VHM) from the SH01 series with positive geometry (chip eject upwards). Designed for efficient cutting, edging and aligning 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 employs four spiral blades (Z4). This ensures high cutting performance, 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 spindle.

Structural advantages and technical properties:

• Four-blade Z4 construction (positive): Four spiral blades with upward chip ejection guarantee efficiency and a clean finish on the lower edge of the workpiece.
• Hybrid geometry (finishing-roughing): The blade profile allows for simultaneous material removal as well as achieving a finished surface after cutting.
• Solid carbide (VHM): The rigid monolithic structure reduces tool deflection under load and helps maintain dimensional accuracy.
• Low shank roughness (Ra ≤ 0.3 µm): The ground shank surface prevents slippage in the tool holder and protects the spindle taper from wear.
• Dynamic balancing in class G2.5: Balancing in accordance with ISO standards ensures stable operation without vibration at high speeds.

Intended use and application range:

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

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