Spiral router bit Roughing VHM Z3 D16 I72 L120 S16 LH positive

Three-flute VHM roughing end mill 16x72 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.16.072.120.16L

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 milling machines and CNC centres. The tool utilises a three-flute spiral geometry with a roughing profile in a Z3 positive configuration, ensuring efficient chip removal upwards and a clean finish on the bottom edge of the workpiece. The dedicated roughing teeth effectively divide the material into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank in a tolerance class of 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 work resistance, efficiently remove material 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 accuracy.
• Possibility of applying a PVD coating: 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 mill from spinning in the holder and eliminates the risk of conical wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balance in the stringent G2.5 class (according to ISO/EN) minimizes noise and reduces vibrations generated at the highest speeds.

Intended use and application range:

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

It works excellently in machining materials such as: softwood and hardwood, plywood, as well as raw particle board and raw MDF board.
