Flap discs are a versatile abrasive disc used on angle grinders for metal fabrication. They are made up of multiple overlapping layers of abrasive material referred to as ‘flaps’, which is how they get their name. Flap discs do both the job of grinding and finishing and are known for their finer finish compared to grinding discs.
There are a few different options you need to be aware of when shopping for flap discs.
Zirconia, ceramic and aluminium oxide are the different types of abrasive grit to choose from. Ceramic flap discs are the most efficient; they cut fast and last approximately 3x as long as zirconia flap discs.
You may come across different backing plates when looking for flap discs. Backing plates hold the flaps together. Fibreglass is the most common option but plastic backing plates are also available.
There are two flap disc shapes. Conical flap discs (or type 29 flap discs as they are also known) are more suited for heavy stock removal. Flat flap discs (type 27 flap discs) are often recommended for blending and finishing. But whether you choose conical or flat flap discs is entirely personal preference.
You then have the choice of grit and diameter. We stock ceramic and zirconium flap discs in 40, 60, 80 and 120 grits and our diameters range from 100mm to 180mm.
In addition we have a wider range of finishing flap discs such as the SAG unitised and also the market leading RCD combination flap disc
The multiple sections flap discs offer ensures extra longevity compared to other grinding discs. Ceramic flap discs are designed to last even longer. Lifespan will depend on use but if you are looking for flap discs that will last the longest, our ceramic products are the ones to shop.
