Spiral router bit Roughing VHM Z3 D12 I35 L80 S12 RH positive TiSiN

3-flute VHM roughing spiral end mill 12x35 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.12.035.080.12TR

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on overhead spindle mills and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a positive configuration Z3, which ensures efficient chip removal upwards and a clean finish on the lower edge of the workpiece. Dedicated roughing teeth effectively break down material into smaller particles, reducing cutting resistance and easing the load on 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 rates while maintaining a clean lower edge.
• Premium solid carbide (VHM) construction: Rigid monolithic design limits tool deflection under load and ensures high dimensional precision.
• TiSiN protective coating: Industrial PVD coating with a hardness of 3570 HV 0.05, thickness of 1–4 µm, and low friction coefficient (0.5) exhibits excellent wear resistance at high temperatures, reduces cutting resistance, protects the cutting edge from overheating, and extends tool life.  
• Low roughness of the shank: The shank surface with a roughness indicator of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of wear on the spindle taper.
• Dynamic balance to G2.5 standard: Certified static and dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and vibrations generated at high speeds.

Application and usage range:

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

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