Spiral router bit Roughing VHM Z3 D12 I42 L90 S12 LH positive

Three-flute roughing VHM spiral end mill 12x42 mm from the SF01 series – maximum performance in rough machining 

Index: SF01.12.042.090.12L

Industrial spiral end mill made of solid cemented 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 a Z3 configuration with a positive arrangement, ensuring effective 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 particles, reducing cutting resistance and relieving the machine's drive system. The ground shank in a tolerance class of H6 minimises radial runout, protecting the spindle and ensuring 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) construction: The rigid monolithic design limits tool deflection under load and ensures high dimensional precision.
• Possibility of PVD coating application: The option to apply protective layers (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 indicator of Ra ≤ 0.3 µm prevents the end mill from rotating in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing at a high class of G2.5 (according to ISO/EN) reduces noise and vibrations generated at high speeds.

Intended use and application range:

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

It works perfectly in machining materials such as: soft and hard wood, plywood, and raw particle board and raw MDF board.
