FAQs

Cutting discs are thin (typically 1mm-3mm) with a sharp edge — designed for cutting metal, stone, or masonry. They cut by abrading along the edge; using them for grinding rapidly destroys the disc and is dangerous. Grinding discs are thick (typically 6mm) with a flat face — designed for grinding, dressing, and material removal across the disc face. Flap discs use overlapping abrasive flaps mounted on a backing pad, providing both grinding and surface finishing in one disc — they remove material faster than grinding discs and leave a finer finish. Each disc type has a designed application and using them off-spec is unsafe.

Match the abrasive grain to the work. Aluminium oxide is the standard for general steel and metal — fast-cutting, good service life. Zirconia is harder-wearing and runs cooler, suiting stainless steel where heat builds quickly and contamination from carbon-steel dust must be avoided (stainless-only discs are clearly marked). Silicon carbide is for stone, masonry, and concrete — different grain structure designed for the harder, brittler materials. Universal discs exist as compromise but always perform less well than application-specific abrasives. Check the disc face and packaging for the intended material.

Both remain widely available — the choice is determined by the angle grinder you have, not by trend. A 4.5-inch grinder takes 115mm discs; a 5-inch grinder takes 125mm discs. The 125mm size is increasingly specified on newer grinders for slightly longer disc life and better cooling, but 115mm remains extremely common across UK trade. 230mm discs are for larger angle grinders used in fabrication and construction — different tool, different application.
