Spiral router bit Roughing VHM Z3 D18 I55 L110 S18 LH positive

VHM three-flute roughing spiral end mill 18x55 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.18.055.110.18L

Industrial spiral end mill made from sintered carbide (VHM) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on gantry milling machines and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a Z3 configuration with a positive layout, ensuring effective chip removal upwards and a clean finish on the bottom edge of the part. Dedicated roughing teeth effectively break the material into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank with 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, effectively remove material upwards, and allow for machining at high feed rates while maintaining a clean bottom edge.
• Premium sintered carbide monolith (VHM): The rigid monolithic structure limits tool deflection under load and ensures high dimensional accuracy.
• Possibility of using PVD coating: Option for applying protective layers (including 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 index of Ra ≤ 0.3 µm prevents the cutter from spinning in the holder and eliminates the risk of cone wear in the spindle.
• Dynamic balancing in G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) eliminates noise and reduces vibrations generated at highest speeds.

Intended use and scope:

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

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