Ingco Flap Disc P80 150x22mm FD1503

Our review

This Ingco flap disc is a 150mm abrasive wheel with a 22mm bore, graded P80, and the manufacturer lists it as suitable for steel, cast iron and sheet steel. Flap discs of this type are usually chosen for grinding, blending and light finishing, where the layered abrasive leaves a more consistent scratch pattern than a solid grinding wheel. P80 sits in the coarser middle of the common range, so it removes material at a fair rate while still leaving a surface you can refine afterwards with a finer disc. It suits someone doing fabrication, weld cleanup or rust and scale removal on steel who wants a disc that can be swapped onto a standard 150mm angle grinder. Before buying, confirm your grinder takes a 150mm disc and that its spindle matches the 22mm bore, since bore and diameter are the two things that decide whether a disc fits at all. Also check the maximum RPM marked on your machine against the disc's rating, and think about whether P80 is the right starting grit for your job or whether you need a coarser grade for heavy stock removal and a finer one for finishing. Compared with other flap discs in this size, the main differences you will weigh are grit, backing material and abrasive type, so match those to the metal you are working rather than assuming any 150mm disc will behave the same. Store discs flat and dry, and inspect them for damage before mounting. This one is available on Sokonia.
