Spiral router bit Roughing VHM Z3 D16 I55 L110 S16 RH positive

Three-flute roughing VHM spiral end mill with 60° drilling tip 16x55 mm from the SF05 series – for door viewers

Index: SF05.16.055.110.16R

Industrial spiral end mill made from solid carbide (VHM) from the SF05 line, designed for rough machining and creating holes for door viewers 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 and a frontal 60° drilling tip, allowing for stable penetration into the material and efficient chip evacuation upwards. The dedicated roughing teeth reduce cutting resistance and relieve 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.

Design advantages and technical properties:

• Z3 roughing design with a frontal 60° drilling tip (upward chip removal): The roughing profile reduces work resistance and efficiently removes material upwards, while the special 60° drilling face ensures clean and precise penetration into the material for door viewers.
• Premium solid carbide (VHM): The rigid monolithic construction limits tool deflection under load and ensures high dimensional precision.
• Option for PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple times the edge life, reduces friction, and protects against overheating.
• Low roughness of the gripping part: The shank surface with a roughness index of Ra ≤ 0.3 µm prevents the mill from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in an advanced G2.5 class (according to ISO/EN) eliminates noise and reduces vibrations generated at the highest speeds.

Intended use and application scope:

The tool is designed for cutting operations, material penetration, creating holes for door viewers, 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.
