If you're cutting metal pipe, rebar, sheet steel, or stainless for automotive, fabrication, or construction work, the disc you choose directly affects your cut quality and job speed. These 0.8mm thin cut-off wheels are built for DIYers and tradespeople who need clean, fast cuts without the frustration.\u003c\/p\u003e\n\u003cp\u003eEach pack contains 50 reinforced fiberglass abrasive cutting discs in your choice of 4 inch (100mm) or 5 inch (125mm) diameter, both with a standard 7\/8\" (22.2mm) arbor. The ultra-thin 0.8mm profile reduces kerf width and heat buildup, while the reinforced fiberglass mesh backing resists shattering under load.
