Spiral router bit Roughing VHM Z3 D6 I22 L70 S6 RH positive

VHM three-flute roughing end mill 6x22 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.06.022.070.06R

Industrial spiral end mill made from 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 positive Z3 configuration, which ensures efficient chip removal 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 alleviating the machine's drive system. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle and guaranteeing a high level of stability during operation.

Design advantages and technical properties:

• Z3 roughing design (upward eject): Three cutting edges with a roughing profile reduce operational 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.
• Possibility of PVD coating: The option to apply protective coatings (e.g., TiSiN or PLATINIUM) can significantly extend edge life, reduce friction, and protect against overheating.
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the end mill from turning 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) minimizes noise and reduces vibrations generated at high speeds.

Intended use and application range:

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

It performs exceptionally well in machining materials such as: soft and hard wood, plywood, and raw particleboard and raw MDF board.
