Cutting Disc and Grinding Disc – Built for Performance, Made to Last

The Right Disc Matters

On any construction site or workshop, time is money. Tools need to work hard without breaking down. But too often, weak or low-quality discs slow things down. They wear out fast, cause rough edges, and even break under pressure. That’s not just costly—it’s dangerous.

At Qingdao Bonterra Industrial Co., Ltd., we offer cutting and grinding discs that handle the tough jobs. Whether you’re working with metal, concrete, or stone, our discs are made for strength, accuracy, and safety. Backed by years of manufacturing expertise, we help professionals work faster with confidence.

We are also proud partners with Bonway Co.—expanding our quality reach even further. We’re not just a supplier—we are part of your building success.

What Is a Grinding Disc?

A grinding disc is a round abrasive tool used to smooth, polish, or shape surfaces. Usually attached to angle grinders, it spins fast and removes material with precision. Grinding discs are used on metal welds, concrete edges, and uneven surfaces. They’re tough and made to last.

At Bonterra, our grinding discs are made with high-strength materials. They offer better balance, longer life, and reduced vibration. That means better results—and less strain on your tools.

What Is a Cutting Disc?

A cutting disc (also called a cut-off wheel) is a thin disc designed to cut through metal, rebar, pipe, and more. Unlike grinding discs, these are used to slice, not shape. They’re ideal for steel, stainless, and even hard stone. Our cutting discs deliver cleaner cuts and reduce sparks—keeping your workspace safer.

From heavy construction to home repair, Bonterra’s cutting discs are trusted by builders and fabricators around the world.
