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

Three-flute roughing solid carbide end mill 16x55 mm from the SF01 series – maximum efficiency in rough machining 

Index: SF01.16.055.110.16R

Industrial spiral end mill made from sintered carbide (solid carbide) from the SF01 line, designed for intensive cutting, preliminary shaping, and efficient rough machining on gantry mills and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a Z3 configuration with a positive layout, which ensures efficient chip removal upwards and a clean finish on the lower edge of the workpiece. The dedicated roughing teeth effectively break the material down into smaller particles, reducing cutting resistance and relieving the machine's drive system. The ground shank with a tolerance class of H6 minimizes radial runout, protecting the spindle and ensuring a high level of stability during operation.

Design advantages and technical properties:

• Z3 roughing design (upward chip ejection): Three cutting edges with a roughing profile reduce work resistance, effectively remove chips upwards and allow for machining at high feed rates while maintaining a clean lower edge.
• Premium sintered carbide monolith (solid carbide): The rigid monolithic structure minimizes tool deflection under load and ensures high dimensional precision.
• PVD coating application possibility: The option to apply protective coatings (including TiSiN or PLATINIUM) allows for multiple extensions of edge life, reduces friction and protects against overheating.
• Low roughness of the clamping part: The surface of the shank has a roughness index of Ra ≤ 0.3 µm, protecting the end mill from rotation in the holder and eliminating the risk of taper wear in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (according to ISO/EN) alleviates noise and reduces vibrations generated at maximum speeds.

Intended use and application range:

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

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