Description

The 7-inch concrete grinding disc is a popular choice for surface preparation on concrete and terrazzo floors, designed to deliver exceptional efficiency and performance. Featuring 10 arrow-shaped segments, it provides aggressive grinding with reduced surface contact, making it ideal for fast material removal. For those requiring higher efficiency, a 12-segment option is also available, better suited for use with more powerful grinders.

Built with a traditional cup body design and multiple cooling holes, this grinding disc ensures smooth water cooling during use, effectively reducing heat buildup and prolonging the tool’s lifespan. High-quality diamonds and metal powders are used in its construction, offering excellent wear resistance, heat resistance, and consistent grinding performance.

With a wide range of diamond grits from 6# to 220# and various bond types available, this grinding disc is suitable for tackling different hardness levels of concrete floors. OEM/ODM services are also supported, allowing full customization of design, grit size, bond type, and branding to meet your unique project needs. Whether for professional or industrial use, this tool is built to deliver outstanding results.

Concrete grinding wheels are available in four main sizes: 100mm, 125mm, 180mm, and 230mm. Each cup wheel is individually packed in a sturdy hard box, available in white, brown, or green, with protective pearl cotton ensuring safe transport. The hardness of the three different colored boxes is as follows: the white box is normal, the brown box is harder, and the green box is the hardest. You can choose from these three materials based on your preference.

Each box features a label displaying a product image, which clearly indicates the type of cup wheel, its diameter, grit, and bond type. This labeling makes it easy for customers to identify and recognize the concrete grinding cup wheels they need.
