Abrasive Grain Type
- Aluminum Oxide
One of the most popular and affordable options, aluminum oxide is highly friable, meaning that it fragments during use to provide a consistently sharp cutting edge. If you strip and finish wood or want to grind metals, there are open and closed coat versions for your application.
- Silicon Carbide
This specialty abrasive is frequently used for finish work because of its consistent cut rate. Its ability to sand material without a lot of heat buildup makes it an ideal option for finishing heat-sensitive applications like resinous wood.
- Ceramic
A premium abrasive grain, ceramic has the longest lifespan of any abrasive material. It cuts energetically through hard woods and metal, its high friability delivering a consistently sharp cutting surface.
- Zirconia
Before ceramic was used, zirconia was the go-to abrasive for durable and aggressive cutting performance. It is still a recommended option for stripping hardwoods and metal grinding and polishing.
