Spiral router bit Roughing VHM Z3 D10 I22 L70 S10 RH positive TiSiN

VHM three-flute roughing end mill 10x22 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.10.022.070.10TR

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, initial shaping, and efficient rough machining on bridge-type milling machines and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a positive Z3 configuration, ensuring efficient chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth effectively break down the material into smaller pieces, reducing cutting resistance and relieving the machine's drive system. The ground shank in H6 tolerance class eliminates radial run-out, protecting the spindle and ensuring a high level of stability during operation.

Construction advantages and technical characteristics:

• Z3 roughing design (upward chip removal): Three cutting edges with a roughing profile reduce work 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 accuracy.
• TiSiN protective coating: Industrial PVD coating with a hardness of 3570 HV 0.05, thickness of 1–4 µm, and a low friction coefficient (0.5) exhibits excellent wear resistance at high temperatures, reduces cutting resistance, protects the edge from overheating, and extends the tool's lifespan.  
• Low roughness of the shank: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the mill from spinning 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 G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at high speeds.

Intended use and application range:

The tool is designed for cutting operations, initial shaping, and efficient rough machining.

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