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

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

Index: SF01.12.035.083.12R

Industrial spiral end mill made from solid carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary formatting, and effective rough machining on overhead spindle milling machines and CNC centres. The tool uses a three-flute spiral geometry with a roughing profile in a Z3 positive configuration, which ensures effective chip removal upwards and a clean finish on the lower edge of the workpiece. The dedicated roughing teeth effectively break 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 ensuring a high level of stability during operation.

Structural advantages and technical properties:

• Z3 roughing design (upward chip evacuation): 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 lower edge.
• Premium solid carbide (VHM): The rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• Ability to apply PVD coating: The option to apply protective coatings (e.g., 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 index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the taper in the spindle.
• 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.

Purpose and application range:

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

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