How to Select a Right Flap Disc
                     HOW TO SELECT A RIGHT 
FLAP DISC
Flap discs are the leading abrasives 
category in metal fabrication. They offer 
fast stock removal and supply grinding, 
blending, and finishing with one 
product, for a lower total cost. Flap 
discs feature cooler cutting with less 
gouging and burning. Flap discs are 
preferred for several reasons, including 
lighter weight, easier-to-control, less 
downtime for product changes, less 
vibration and resulting fatigue, and also 
reduced noise.
WHAT ARE FLAP DISCS?
• Flap discs are constructed with multiple overlapping pieces of 
abrasives called 'flaps' and are an essential component of a 
grinder. They are designed for right-angle grinder applications 
starting from heavy stock removal to surface blending and smooth 
finishing.
• Flap discs are similar to emery wheels, but they yield very different 
results counting on the project.
• They're made with an equivalent grain found in abrasives, but the 
grains' arrangement within the discs gives them a softer feel.
HOW TO SELECT THE PROPER 
FLAP DISC
The abrasive material of flap discs largely determines its effectiveness; 
the first types are:
• Zirconium Alumina
• Ceramic Alumina
• Aluminum Oxide
Here are some points to be considered while selecting flap disc 
• Choosing the Right Abrasive • Plastic Backing Plates 
• Proper Flap Disc Grit size • Fiberglass Backing Plates
• Shape of the Flap Disc • Aluminum Backing Plates
• Backing Plate Material • The density of the flaps
