Spiral router bit Roughing VHM Z3 D12 I35 L83 S12 LH positive

VHM three-edge roughing spiral mill 12x35 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.12.035.083.12L

Industrial spiral mill made of solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on vertical milling machines and CNC centres. The tool features a three-edge spiral geometry with a roughing profile in Z3 positive configuration, ensuring efficient chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth effectively break up 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 guaranteeing a high level of stability during operation.

Design advantages and technical properties:

• Z3 roughing design (upwards chip removal): Three cutting edges with a roughing profile reduce workload 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.
• PVD coating option: The option to apply protective coatings (such as TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction, and protects against overheating.
• Low roughness of the clamping part: The stem surface with a roughness index of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wear on the taper in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) reduces noise and minimizes vibrations generated at the highest speeds.

Application and scope of use:

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

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