What's the main difference between these flap discs and a normal grinding wheel?

Flap discs are good for both grinding down material and finishing in one go, so you get a smoother surface. These zirconium oxide discs are especially good for stainless steel but also work on mild steel, wood, and plastic.

How do I know which grit size to order for my job?

For heavy material removal or grinding down welds, use a coarse 40 grit. For blending, deburring, and general finishing, an 80 or 120 grit will give you a much smoother result.

Will these fit my 5-inch angle grinder?

Yes, they will. These are 125mm (5-inch) diameter discs and have a standard 22mm centre hole, so they're designed for all common 125mm angle grinders.

This 125mm flap disc is a grinding wheel that removes material and finishes the surface. It does both in one step. Unlike a standard grinding wheel, its angled flaps cut cooler on metal. This reduces discoloration. It fits any standard 5-inch angle grinder. Features and Benefits - Overlapping abrasive flaps - As the disc wears, new grit shows. This gives a steady cutting rate throughout its life. - Grit options (40-120) - Pick a coarse 40 grit for fast weld removal. Or choose a finer 120 grit for blending stainless steel. - Zirconia alumina abrasive - Stays sharp and self-cools when grinding. This makes it good on both carbon and stainless steel. - Fiberglass backing plate - Absorbs vibrations for more comfortable use. It wears away with the flaps for full use of the disc. Applications - Removing heavy stock, grinding down welds, and blending surfaces on metal fabrication projects. - Cleaning rust, scale, and old paint from steel surfaces to get them ready for coating. - Deburring and chamfering the edges of freshly cut metal plates and pipes.
