Spiral router bit Roughing VHM Z3 D8 I32 L80 S8 LH positive NaDia

VHM three-flute roughing spiral end mill 8x32 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.08.032.080.08XL

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, pre-forming, and efficient rough machining on overhead spindle milling machines and CNC centres. The tool features a three-flute roughing spiral geometry in a positive Z3 configuration, ensuring efficient chip evacuation upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth effectively break the material into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank with a tolerance class of H6 eliminates radial runout, protecting the spindle and ensuring a high level of stability during operation.

Design advantages and technical properties:

• Z3 roughing design (upwards discharge): Three cutting edges with a roughing profile reduce working resistance, efficiently evacuate chips upwards, and allow for machining at high feed rates while maintaining a clean bottom edge.
• Premium solid carbide (VHM): The rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• NaDia protective coating: A specialist black PVD coating with a hardness of 3650 HV 0.05, a thickness of 1–4 µm, and an extremely low friction coefficient (0.01–0.05) exhibits exceptional wear resistance, reduces cutting resistance, prevents material sticking, and significantly extends tool life.  
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm secures the mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent G2.5 class (according to ISO/EN) reduces noise and vibration generated at high speeds.

Intended use and application scope:

The tool is designed for cutting, pre-forming, and efficient rough machining operations.

It performs excellently in machining materials such as soft and hard wood, plywood, as well as raw particle board and raw MDF board.
