Zirconia Flap Disc 80 Grit

This zirconia flap disc is a 127mm disc with a 22mm bore, dressed in 80 grit (medium) zirconia flaps for stock and weld removal plus grinding and clean up work. It is a good all round grade for steel, cast iron, aluminium and most metals, and it is built to replace sanding discs on an angle grinder without a backing pad. The cloth backed flaps cushion the cut, so a medium grit disc can remove stock quickly and still leave a finish that paint and coatings sit on well.

What You Need To Complete The Job

Use this 80 grit disc for the middle step between coarse and fine, pairing it with the 40 grit for heavy removal and the 120 grit for finishing. Grinding produces sparks and fine grit, so wear clear safety glasses and gloves. Browse the Power Tools range for grinders and accessories.

Frequently Asked Questions

What is the 80 grit flap disc used for?

80 grit is the medium step in the flap disc range. It removes stock and welds while leaving a surface that is smoother than a coarse 40 grit disc. It suits grinding and clean up on steel, cast iron and aluminium, and it is a common choice for blending a surface before paint or a protective coating.

Can I use flap discs without a backing pad?

Yes. Flap discs are designed to fit straight onto the spindle of an angle grinder, which removes the need for a backing pad. The cloth backing and the hub are built to take the load. Always use the correct guard for the grinder and check that the disc RPM rating suits your machine.

Why is there a brand difference between the SKU and the description?

The SKU field reads as part of the Josco number sequence, while the description text refers to a Brumby part number (BDZ12780) with a different barcode. The store listing carries both, and the two do not match exactly. We have kept the SKU field unchanged and flag it for supplier verification before the product is submitted to a shopping feed.
