Starflex FZ129 – Zirconia fibre disc P36 for stainless steel 125 mm

Starflex FZ129 fibre disc with zirconia grain in P36 grit is an abrasive tool designed for intensive machining of stainless steel. The aggressive zirconia grain ensures high material removal efficiency from the first contact with the surface whilst guaranteeing long service life of the disc — which directly translates to reduced consumable wear on construction sites and in workshops.

The 125 mm diameter with 22 mm mounting hole corresponds to the most popular angle grinders, making the disc ready to work without additional adapters. The maximum operating speed is 80 m/s, ensuring safe and stable operation at high speeds.

Zirconia grain — why choose it?

Zirconia grain is distinguished by its crystalline, uniform structure which provides exceptional hardness and toughness simultaneously. In practice, this means that the self-sharpening disc maintains cutting aggressiveness throughout its service life — instead of becoming blunt, the grains fracture microscopically, exposing fresh sharp edges. What is crucial for installers working with stainless steel — zirconia grain contains no iron or sulphur, which could cause corrosion of the machined surface.

Health and safety requirements

When working with the fibre disc, full protective equipment must be used: eye and face protection, protective gloves, hearing protection and respiratory protection. Before starting grinding, ensure that the grinder speed does not exceed the permissible peripheral speed of the disc.
