Star Flex – cutting disc for steel and INOX 125 × 2.5 mm (type 41)
Description
Star Flex – cutting disc for steel and INOX 125 × 2.5 mm (type 41)
Star Flex cutting disc 125 × 2.5 mm is a universal abrasive tool designed for cutting carbon steel, stainless steel (INOX) and acid-resistant steel. Thanks to its enhanced hardness grade R and synthetic resin bond reinforced with fibre, it ensures long service life and rapid work progress — even with intensive use on construction sites and in workshops.
The type 41 (flat) disc is compatible with standard 125 mm angle grinders. Corundum abrasive with 30 grit guarantees aggressive, clean cutting with minimal material heating — which is particularly important when working with stainless steel, where overheating leads to discolouration and structural weakening.
Benefits for installation teams
- Rapid cutting progress — high cutting ability reduces working time on site
- High economy — enhanced R hardness extends disc life, reducing consumable material usage
- Versatility — one disc for carbon, stainless and acid-resistant steel eliminates the need for tool changes
- Safety — product compliant with EN 12413 standard, ISO 9001 quality system

Construction and build quality
The disc features fibre mesh reinforcement visible on the rear side, which prevents disc breakup at high speeds and ensures safe use even under intensive side loading. The synthetic resin bond provides resistance to high temperatures generated during cutting, and the corundum abrasive grains self-sharpen as they wear — maintaining constant cutting aggressiveness throughout the service life.
Star Flex is a brand by Postal Steel Group, appreciated for years by workshops and installation companies in Poland and abroad. Star Flex abrasive tools combine high working performance with reliability and safety — ideal for daily use on construction sites.
