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

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

Index: SF01.20.102.165.20L

Industrial spiral end mill made from solid cemented carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and effective rough machining on gantry milling machines and CNC centres. The tool features a three-flute spiral geometry with a roughing profile 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 break the material into smaller particles, 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 working resistance, efficiently remove chips upwards, and allow for machining at high feed speeds while maintaining a clean bottom edge.
• Premium solid cemented carbide (VHM): The rigid monolithic design limits tool deflection under load and ensures high dimensional accuracy.
• Option for PVD coating: The option to apply protective layers (including 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 index 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) mitigates noise and reduces vibrations generated at high speeds.

Intended use and application range:

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

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