4in 100mm Diamond Cup Wheel Double Row Concrete Masonry Grinding Disc 7/8 Arbor

Rough concrete edges, uneven masonry, brick surfaces, and stone areas can be difficult to smooth with a regular abrasive wheel. This 4 in / 100mm diamond double-row cup wheel is designed for compatible angle grinders to help grind concrete, brick, natural stone, paving slabs, cement masonry, and similar hard building materials.

Double-Row Diamond Segments For Surface Grinding

• 4 Inch Diamond Cup Wheel: Approx. 100mm / 3.937 in diameter makes it suitable for compatible angle grinders that accept this size and arbor.
• Double-Row Segment Design: Two rows of diamond grinding segments increase surface contact for faster and more even material removal.
• Made For Hard Materials: Designed for grinding concrete, brick, natural stone, paving slabs, cement masonry, and similar construction surfaces.
• 22.23mm Center Hole: Arbor hole measures approx. 22.23mm / 0.875 in based on the product image. Please confirm grinder compatibility before ordering.
• Durable Diamond Grit: Diamond abrasive segments help handle heavy grinding workloads better than standard abrasive discs.
• Surface Prep Use: Useful for leveling high spots, smoothing rough concrete, cleaning masonry surfaces, shaping edges, and preparing surfaces for repair work.

Good For Concrete, Brick, Stone, And Masonry

This diamond cup grinding wheel can be used on concrete steps, brick surfaces, natural stone, paving slabs, cement masonry, and similar hard materials. It is intended for grinding and surface preparation, not for cutting through material like a saw blade.

Fit And Use Notes

Please check your angle grinder size, arbor hole, guard clearance, and RPM rating before ordering. This wheel has a 22.23mm / 0.875 in center hole based on the product image. Adapter hardware is not listed as included. Do not use if your tool does not match the wheel specifications.

Safety Notes

Always wear eye protection, gloves, hearing protection, and a dust mask when grinding concrete, stone, brick, or masonry. Use a grinder guard and follow your tool manufacturer’s instructions. Grinding dust may be harmful, so work in a well-ventilated area and use proper dust control.
