Spiral router bit Roughing VHM Z3 D16 I55 L110 S16 LH positive NaDia

Three-fluted roughing VHM end mill 16x55 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.16.055.110.16XL

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on 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 effective chip removal upwards and a clean finish on the lower edge of the part. The dedicated roughing teeth effectively divide the material into smaller pieces, reducing cutting resistance and relieving the machine's drive system. The ground shank in tolerance class H6 eliminates radial run-out, protecting the spindle and guaranteeing a high level of stability during operation.

Structural advantages and technical properties:

• Roughing Z3 design (upward chip evacuation): Three cutting edges with a roughing profile reduce working resistance, efficiently remove chips upwards, and allow for machining at high feed rates while maintaining a clean lower 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, thickness of 1–4 µm, and an extremely low friction coefficient (0.01–0.05) exhibits exceptional wear resistance, reduces cutting resistance, prevents material adhesion, and significantly extends tool life.  
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm secures the end mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in an advanced class G2.5 (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds.

Application and scope of use:

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, and raw particle board and raw MDF board.
