1-1/2" x 30" Metalworking Sanding Belts, 48 PACK

1-1/2" x 30" Metalworking Sanding Belts WHAT IS THE BEST SANDING BELT FOR SANDING ALUMINUM? When you are sanding aluminum you have two options of abrasive grain/material for you to choose from. Aluminum Oxide – The benefits of going with aluminum oxide are that it is very cost effective if you are looking to spend the least amount possible. You will get decent life and reasonable cutting ability. This is probably the most common material purchased as a result. It is important to note that our aluminum oxide cloth backed belt is poly-cotton, meaning it can be ran wet or dry. Zirconia – Zirconia is by far the more premium option for many reasons. Zirconia sanding belts provide far superior cutting power, cutting speed, reduced heat generation and longevity of the belt. Zirconia sanding belts will last about 2 to 3 times longer than aluminum oxide belts! The only downside is that zirconia is only available in 24 grit, 36 grit, 40 grit, 50 grit, 60 grit, 80 grit, 100 grit & 120 grit
