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

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

Index: SF01.16.072.120.16R

Industrial spiral end mill made from solid tungsten carbide (VHM) from the SF01 line, designed for intensive cutting, initial shaping, and efficient rough machining on machining centres and CNC machines. The tool features a three-flute spiral geometry with a roughing profile in a Z3 positive configuration, which ensures efficient chip evacuation upwards and a clean finish on the bottom edge of the workpiece. Dedicated roughing teeth effectively break down the material into smaller particles, reducing cutting resistance and easing the load on the machine's drive system. The ground shank in H6 tolerance class eliminates radial runout, protecting the spindle and guaranteeing a high level of stability during operation.

Design strengths and technical properties:

• Z3 rough construction (upward chip removal): Three cutting edges with a roughing profile reduce operating resistance, efficiently remove chips upwards, and allow for machining at high feed rates while maintaining a clean bottom edge.
• Premium sintered carbide monolith (VHM): The rigid monolithic construction limits tool deflection under load and ensures high dimensional accuracy.
• PVD coating application possibility: 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 gripping part: 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 wear on the spindle cone.
• Dynamic balancing within 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.

Intended use and application range:

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

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