6 x 48 Abrasive Sanding Belts - Material Facts

AA Abrasives, Inc. carries abrasive sanding belts for metal and wood finishing applications. We are featuring the 6x48 Sanding Belt  - AA Abrasives sanding belts are for use with belt sanders like the Kalamazoo S6 Belt Sander  and other bench style belt sanders and belt/disc sanders.

Abrasive Sanding Belts

AA Abrasives premium zirconia and aluminum oxide abrasive belts deliver sharp and durable performance. Resin bond anchors the abrasive to the backing for longer belt life. The abrasive belts feature bi-directional, high-strength butt joints that can be run in either direction increasing the total service life of the belt. Our high quality abrasive belts are for wood, metal and heavy stock removal. AA Abrasives sanding belts are made from the finest quality materials for long life and are manufactured in the USA.

AA Abrasives has a full line of heavy-duty cloth-backed abrasive belts in stock. One of the best 6 x 48 sanding belts we supply is a self-sharpening 36 Grit zirconia aluminum abrasive belt.  This premium zirconia alumina abrasive belt for metal delivers sharp and durable performance. The premium grade zirconia alumina breaks away in use to expose new sharp edges. The abrasive is bonded to the Y-weight polyester backing with industrial strength proprietary resins in a closed coat arrangement to allow maximum stock removal. A closed coated abrasive belt is one that has 100% grain coverage.  Heavy Y-weight polyester backing is tear resistant and tracks consistently.

The two most popular Aluminum Oxide abrasive belts in 6x48 are the 6 x 48 Sanding Belt in 60 Grit Aluminum Oxide Premium  and the 6 x 48 Sanding Belt in 80 Grit Aluminum Oxide Premium. The premium aluminum oxide abrasive belts cut fast and perform well on all grains of woods  as well as other surfaces. AA Abrasives belts have a closed coat construction making them ideal for deburring or producing a grain pattern in metalworking. The closed coat construction provides improved finishes on harder woods. Y-weight poly-cotton backing makes a good general purpose belt for dry sanding applications. The resin bond of this sanding belt withstands high heat and pressure for longer service life.

For polishing applications AA Abrasives, Inc. carries a full range of preparation and conditioning abrasive belts in 6” wide x 48” long such as the 6 x 48 Medium Surface Conditioning Belt. These non-woven nylon belts have a scrim reinforcement for extra strength and an abrasive resin bond which polishes and deburrs metal surfaces. They are available in coarse, medium, and fine.

T-1 means the grinding wheel is flat. This is also referred to as a Type 1 Grinding Wheel or a straight toolroom wheel;

Vitrified is the bonding of grinding wheel;

A36 - A means it is an aluminum oxide grinding wheel and the 36 means the grinding wheel is composed of a medium grain size also known as grit.  See the grain size chart below.

A/O  also means aluminum oxide;

RPM is the Revolutions Per Minute or Maximum Operating Speed  - not all specifications will show this. The tool, the grinding wheel and application must be in agreement to ensure safe operation.
