7 Inch Concrete Grinding Disc for Floor Coating removals

Description

This 7-inch (180mm) concrete grinding disc with zigzag-shaped segments is specially designed for rough grinding tasks on concrete or terrazzo floors and for efficient removal of floor coatings like paint, adhesives, or epoxy. Its unique zigzag segment design provides aggressive grinding performance, ensuring fast material removal and smooth surface preparation.

Under the same pressure, the smaller the contact area between the segments and the concrete floor, the more aggressive the grinding action becomes. By equipping the disc with only 6 zigzag-shaped segments, we increase the pressure on each segment, enhancing its ability to grind more effectively. This design allows for faster and easier removal of general floor coatings, making the grinding process more efficient. The reduced number of segments ensures that each one performs at its highest capacity, improving the overall speed and performance of the floor preparation or coating removal task.

Crafted with durable, high-quality diamond grit, this grinding disc offers excellent wear resistance and long service life, even under heavy-duty applications. The disc is compatible with most standard floor grinders and comes with various arbor sizes for easy installation. Whether for surface preparation or coating removal, this grinding disc is a reliable choice for professionals. Customization options for logo and packaging are also available to meet branding needs.

Packaging methods – 7 inch concrete grinding disc

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.
