SHDIATOOL Turbo Row 4-1/2 Inch Diamond Grinding Cup Wheel — 7/8 Inch Arbor for Concrete, Granite, Marble

Upgrade your surface preparation with the SHDIATOOL Turbo Row Diamond Grinding Cup Wheel. Sized for 4-1/2 inch grinders and compatible with a 7/8 inch arbor, this cup wheel blends aggressive material removal with a controlled, flat finish. The Turbo Row arrangement places 24 diamond segments in a geometry that promotes steady cutting and helps maintain a consistent edge across concrete, masonry, granite, marble, and brick surfaces.

What makes it perform

• Turbo Row design with 24 diamond segments delivers a more uniform grind and reduces edge chatter.
• 115 mm outside diameter (4-1/2 inch) with a 3 mm steel body and 4.5 mm usable thickness for durability and stability.
• 40–50 diamond grit provides versatile material engagement across concrete, masonry, granite, marble, and brick.
• 7/8 inch arbor compatibility keeps your grinder secure during repeated passes.

Materials and surfaces you can refresh

• Concrete floors and sidewalks — smooths rough patches, levels imperfections, and prepares surfaces for finishing coats.
• Masonry walls and bricks — cuts and shapes with consistent edge quality.
• Natural stone such as granite and marble — opens up through hard surfaces while maintaining control.

Real-world use cases

This cup wheel excels in prep work before coatings, refinishing floors, or removing thin-set, grout lines, or old sealants. Expect quicker material engagement and a steadier guide feel with each pass and a more uniform edge after grinding.

Pair with a steady grinder, appropriate PPE, and measured feed rates to optimize results. Use in dry or light-wet conditions as your project requires, and inspect the wheel for wear to maintain consistent performance.
