Spiral router bit Roughing VHM Z3 D12 I42 L90 S12 RH positive NaDia

VHM three-flute roughing end mill 12x42 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.12.042.090.12XR

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

Structural advantages and technical properties:

• Z3 roughing design (upward chip removal): Three cutting edges with a rough profile reduce work resistance, efficiently remove chips upwards and allow for machining with 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 accuracy.
• NaDia protective coating: A specialist black PVD coating with a hardness of 3650 HV 0.05, thickness of 1–4 µm and an extremely low friction coefficient (0.01–0.05), demonstrating exceptional wear resistance, reducing cutting resistance, preventing material build-up and significantly extending tool life.  
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents 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 the stringent G2.5 class (according to ISO/EN) eliminates noise and reduces vibrations generated at the highest speeds.

Intended use and application range:

The tool is intended for cutting, preliminary shaping and efficient rough machining.

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