Flap Discs

Flap Discs

Used with angle grinders, flap discs are made with layered abrasive-covered flaps mounted on a rigid backing that enables grinding and finishing in one step. They provide a smoother, cooler, and more controlled grind than grinding wheels while providing longer life, a more consistent finish, and less buildup than fiber discs. Choose lower grit numbers or coarser grits for an even, smooth finish, and higher grit numbers or finer grits for a fine, polished finish.

General Purpose Flat (Type 27)

Sand a wide variety of flat materials, including metals and wood, with these flat Type 27 discs. Providing a balance of toughness and strength, these flap discs are made with aluminum oxide abrasive, which is the most commonly used abrasive.

Long-Life Flat (Type 27)

These flat-faced (Type 27) discs are the simple solution for heavy material removal on flat surfaces. The zirconia alumina abrasive is hard, tough, and long lasting and is suitable for use on metals like stainless steel and for wood planing.

Long-Life Angled (Type 29)

With an angled cutting surface that makes more contact with the workpiece surface than flat (Type 27) discs, these Type 29 discs aggressively remove material, especially on contoured surfaces and have zirconia alumina abrasive for extended life. Zirconia alumina is hard, tough, and long lasting, making it suitable for heavy material removal on stainless steel and other metals and for wood planing.

Cool & Fast Cutting Flat (Type 27)

For blending and finishing flat surfaces, these Type 27 discs have a flat face and are coated with ceramic abrasive, which is tough, stays cooler, requires less pressure, and lasts longer on hard materials than general-use aluminum oxide and long-life zirconia alumina abrasive. Ceramic abrasive is suitable for use on stainless steel and other hard metals.

Cool & Fast Cutting Angled (Type 29)

Angled for aggressive material removal, these Type 29 discs are coated with ceramic abrasive, which is tough, stays cooler, requires less pressure, and lasts longer on hard materials than long-life zirconia alumina and is suitable for use on stainless steel and other hard metals. The angled face of a Type 29 disc makes more contact with the workpiece surface than flat (Type 27) discs for more material removal, especially on contoured surfaces.

Nylon Webbed for Finishing & Conditioning

Clog-resistant and gentle on workpieces, these discs are used to finish and condition a variety of materials. The nylon construction maintains flexibility for sanding without altering the shape of the workpiece while the webbed construction allows debris and dust to fall through the disc and resists clogs.

Radial for Edges

The flaps of these discs are connected to the core in a radial pattern, which gives them more flexibility for sanding welds, edges, and corners compared to flat (Type 27) discs. They are commonly used on fillet welds where two pieces of metal overlap.
