Spiral router bit Roughing VHM Z3 D20 I102 L165 S20 RH positive

Three-flute roughing VHM spiral end mill 20x102 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.20.102.165.20R

Industrial spiral end mill made from solid cemented 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 roughing geometry in a Z3 configuration with a positive layout, 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's drive system. The ground shank with a tolerance class of 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 roughing profile reduce operating resistance, efficiently remove chips upwards, and allow machining at high feed rates while maintaining a clean bottom edge.
• Monolithic Premium cemented carbide (VHM): Rigid monolithic construction limits tool deflection under load and ensures high dimensional accuracy.
• Possibility of PVD coating application: The option to apply protective coatings (e.g. TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• 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) reduces noise and vibrations generated at high speeds.

Intended use and application range:

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

It is ideal for processing materials such as soft and hard wood, plywood, and raw particle board and raw MDF board.
