Spiral router bit Roughing VHM Z3 D14 I58 L110 S14 RH positive

VHM three-flute roughing spiral cutter with a 60° drilling tip 14x58 mm from the SF05 series – for door viewers

Index: SF05.14.058.110.14R

Industrial spiral cutter made of solid sintered carbide (VHM) from the SF05 line, designed for rough machining and creating holes for door viewers on overhead milling machines and CNC centres. The tool features a three-flute spiral geometry with a roughing profile in a Z3 configuration with a 60° front drilling tip, enabling stable penetration into the material and effective upward chip removal. The dedicated roughing tooth design reduces cutting resistance and relieves the machine's drive system. The ground shank with a tolerance class of H6 mitigates radial runout, protecting the spindle and ensuring a high level of stability during operation.

Structural advantages and technical properties:

• Z3 roughing design with a 60° front drilling tip (upward chip evacuation): The roughing profile reduces working resistance and effectively removes chips upwards, while the special 60° drilling tip ensures clean and precise penetration into the material for door viewers.
• Premium sintered carbide monolith (VHM): The rigid monolithic structure limits tool deflection under load and ensures high dimensional precision.
• Possibility of applying a PVD coating: The option to apply protective layers (including TiSiN or PLATINIUM) allows for multiple extensions of edge lifespan, reduces friction and protects against overheating.
• Low roughness of the shank: The surface of the shank with a roughness index of Ra ≤ 0.3 µm prevents the cutter from rotating in the holder and eliminates the risk of wear on the cone in the spindle.
• Dynamic balancing to G2.5 standard: Certified static-dynamic balancing in the stringent G2.5 class (in accordance with ISO/EN) minimises noise and reduces vibrations generated at high speeds.

Intended use and scope:

The tool is designed for cutting operations, material penetration, creating holes for door viewers, and efficient rough machining.

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