Spiral router bit Roughing VHM Z3 D12 I52 L100 S12 LH positive

VHM three-flute roughing spiral end mill 12x52 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.12.052.100.12L

Industrial spiral end mill made from a solid carbide (VHM) from the SF01 line, designed for intense 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 positive configuration Z3, which ensures 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 minimises 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 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: The option to apply protective layers (e.g., TiSiN or PLATINIUM) allows for multiple extensions of edge lifespan, reduces friction, and protects against overheating.
• Low roughness of the shank: The shaft surface with a roughness index of Ra ≤ 0.3 µm protects 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 in the stringent class G2.5 (according to ISO/EN) minimises noise and reduces vibrations generated at maximum speeds.

Intended use and application range:

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

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