Spiral router bit Roughing VHM Z3 D20 I60 L120 S20 RH positive

Three-flute roughing solid carbide end mill 20x60 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.20.060.120.20R

Industrial solid carbide end mill (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient roughing on spindle milling machines and CNC centres. The tool features a three-flute spiral geometry with a rough profile in the Z3 configuration with a positive layout, ensuring 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 rough profile reduce working 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.
• Option for PVD coating: The option to apply protective coatings (including TiSiN or PLATINIUM) can significantly extend the tool's edge life, reduce friction, and protect against overheating.
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wear on the spindle cone.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent class G2.5 (according to ISO/EN) minimizes noise and reduces vibrations generated at the highest speeds.

Application and range of use:

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

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