Spiral router bit Roughing VHM Z3 D8 I42 L90 S8 RH positive

VHM three-flute roughing end mill 8x42 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.08.042.090.08R

Industrial spiral end mill made of solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary profiling, 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 allows for 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 pieces, reducing cutting resistance and relieving the machine's drive system. The ground shank in tolerance class H6 eliminates radial runout, protecting the spindle and ensuring a high level of stability during operation.

Design 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 for machining at high feed rates while maintaining a clean bottom edge.
• Premium solid carbide (VHM) construction: The rigid monolithic structure limits tool deflection under load and ensures high dimensional precision.
• Possibility of PVD coating applications: Option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction and protects against overheating.
• Low roughness of the gripping part: 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 wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (in accordance with ISO/EN) reduces noise and vibrations generated at high speeds.

Intended use and application range:

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

It performs excellently in the processing of materials such as: soft and hard wood, plywood, as well as raw chipboard and raw MDF board.
