Spiral router bit Roughing VHM Z3 D16 I72 L120 S16 RH positive NaDia

Three-flute VHM roughing spiral end mill 16x72 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.16.072.120.16XR

Industrial spiral end mill made from solid carbide (VHM) 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 positive configuration, which ensures efficient chip evacuation upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing tooth geometry effectively breaks the material into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank in class tolerance H6 eliminates radial runout, protecting the spindle and guaranteeing a high level of stability during operation.

Constructive advantages and technical properties:

• Z3 roughing design (upward chip evacuation): Three cutting edges with a roughing profile reduce work resistance, efficiently remove material upwards, and allow for machining at high feed speeds while maintaining a clean bottom edge.
• Premium solid carbide (VHM) construction: The rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• NaDia protective coating: A specialized black PVD coating with a hardness of 3650 HV 0.05, thickness of 1-4 µm and an extremely low coefficient of friction (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 indicator of Ra ≤ 0.3 µm secures the end mill against rotating in the holder and eliminates the risk of wearing the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in an ultra-strict G2.5 class (according to ISO/EN) minimizes noise and reduces vibrations generated at high speeds.

Intended use and range of application:

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

It works perfectly in machining materials such as: soft and hard wood, plywood, and raw particle board and raw MDF board.
