Spiral router bit Roughing VHM Z3 D10 I42 L90 S10 RH positive NaDia

Three-flute roughing solid carbide end mill 10x42 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.10.042.090.10XR

Industrial spiral end mill made from a solid carbide (VHM) blank from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on vertical 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, which ensures 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 drive system. The ground shaft with a tolerance class of H6 eliminates radial runout, protecting the spindle and ensuring a high level of stability during operation.

Construction advantages and technical characteristics:

• Z3 roughing design (upward chip removal): Three cutting edges with a roughing profile reduce work resistance, efficiently remove 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 shank surface with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wearing out the cone in the spindle.
• Dynamic balance meeting G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds.

Intended use and application range:

The tool is intended for cutting, preliminary shaping, 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.
