Spiral router bit Roughing VHM Z3 D20 I72 L120 S20 RH positive

Carbide three-flute roughing spiral end mill 20x72 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.20.072.120.20R

Industrial spiral end mill made of solid sintered 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 positive Z3 configuration, which ensures effective chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth efficiently break the workpiece 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 guaranteeing 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 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 design limits tool deflection under load and ensures high dimensional precision.
• Possibility of PVD coating application: The option of applying protective coatings (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 indicator of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wearing out the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in a stringent class G2.5 (according to ISO/EN) reduces noise and diminishes vibrations generated at high speeds.

Application and range of use:

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

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