How to choose abrasives in metalworking

Metalworking needs special abrasives to grind, finish, or polish to ensure a satisfactory surface. We have recommendations as well as information about which abrasive to choose for your project.

• Bonded
• Coated
• Non-woven

Also, see more information about the minerals related to abrasives.

1. Bonded

Bonded discs are just like they sound. The mineral, binding agent, and some type of reinforcement material are fused together to form a hard disc.

2. Coated

Coated discs are just like they sound, too. They have mineral-coated backing (using some sort of resin, much like glue). They’re durable and flexible. They come in many different forms, not just discs.

3. Non-woven

Non-woven are sometimes called by a brand name: Scotch-Brite (a 3M proprietary disc). These discs are made up of a fibrous material that the abrasive minerals are adhered to with a resin, similar to a coated disc, but in a more random pattern. They offer great conform-ability, flexibility, cleaning action ease, and add a grain pattern to the project.

Minerals

• Aluminum oxide: Widely used. Cost-effective. Fractures into sharper pieces until it wears down.
• Silicon carbide: Starts out sharp and cuts well. Wears quickly and doesn’t always fracture cleanly.
• Zirconia alumina: Combines the sharpness and cutting power similar to silicon carbide, but fractures to a sharp edge as it wears.
• Ceramics: Combines or more minerals with ceramic bits for a durable cutting combination that’s heat-resistant.
• Precision-shaped grain: Precision-shaped grain is a ceramic blend that can include 3M’s proprietary Cubitron II mineral.
