Starflex cutting disc for steel and INOX T41 400×4.0×32 mm WA30R-BF
Description
Starflex cutting disc for steel and INOX T41 400×4.0×32 mm WA30R-BF

Starflex T41 cutting disc with 400 mm diameter is a durable tool designed for intensive cutting of mild steel, stainless steel (INOX) and acid-resistant steel. The enhanced hardness of R grade abrasive ensures long disc life even during continuous workshop operation, directly translating to lower tool cost per cut. The flat type 41 construction guarantees precise, straight cuts in profiles, sheets and pipes with large cross-sections.
Thanks to its 4.0 mm thickness, the disc maintains high rigidity during operation, minimising the risk of deformation and vibration — particularly important when cutting components on stationary cut-off machines. The corundum abrasive grain with 30 grit provides aggressive, rapid cutting progress, reducing operation time and increasing team efficiency on construction sites or in workshops.

Application and purpose
The disc is designed for cutting structural steel, stainless steel and acid-resistant steel. The INOX designation confirms its safety for use on austenitic steels — the abrasive contains no iron or sulphur compounds that could cause corrosion in the cutting zone. An ideal tool for work on steel structures, industrial installations, pipelines and machining stainless steel components in manufacturing facilities.

Key advantages for installers
- Fast cutting progress — aggressive 30 grit reduces time for each operation
- High durability — hard R grade abrasive provides significantly longer working life compared to soft discs
- Material versatility — mild steel, stainless steel and acid-resistant steel with one disc
- Fibre-reinforced bond (BF) — increased crack resistance and work safety at high speeds
- Large 400 mm diameter — allows cutting of large cross-section elements without multiple passes
