WHAT IS AN ABRASIVE FLAP DISC?

An abrasive flap disc can help you grind and finish metal surfaces with one tool attachment. Flap discs grind like a depressed center wheel and finish like a fiber sanding disc – helping you reduce process time and lower your total grinding costs.  

Technically speaking, Type 27 Flat flap discs have a flat flap design and provide the best finish. These tend to be the most popular and commonly used. Type 27 Flap Discs are used primarily on flat surfaces they grind at flatter angles 0° to 15°.

Type 29 Conical flap discs are the more aggressive choice, with flaps angled at 10°. The angle provides greater surface contact. A Type 29 flap disc can be used on both irregular and flat surfaces and grinds at steep angles 15° to 25°.

Choose an angled flap disc-Type 29 for faster stock removal. An angled edge can be used with a vertical or horizontal grinder. And with the angled edge, more of the abrasive disc contacts the metal surface, helping you strip and finish in less time.

Flap discs are most commonly used on right angle grinders and vertical shaft portable grinders. You may be using a tool like the Metabo Angle Grinder W8-115 or a Dynabrade 53232 Vertical Depressed Center Wheel Grinder.

We only offer high quality flap discs because we have found that poor quality flap discs on the market tend to “chatter” during the grinding process and generate vibrations.  This can result in the grit pulling away from the mounting prematurely giving you irregular grinding, poor grinding capacity, short service life and potential flap tearing. AA Abrasives Flap Discs are made with premium zirconia alumina grain on a phenolic backing.  Zirconia-alumina is best for medium- to heavy-material removal. The grains constantly fracture to produce new sharp edges. Flap discs made from zirconia-alumina are commonly used on carbon steels, aerospace alloys, nickel alloys, aluminum, cast iron, forgings and some stainless steels. These flap discs are made in the USA.

If you use flap discs - try our high quality flap disc line.  Our most popular flap discs are the Zirconium in 4-1/2" and 7" with a 7/8" arbor hole.
