The double-row diamond segments provide a faster, more aggressive grinding action with efficient material removal and more even wear, helping you finish surfaces quicker.

This wheel is designed for 115 mm grinders with a standard arbor (universal fitment). It typically works with most brands that use a 5/8 inch-11 UNC arbor. Always verify your tool’s arbor and speed rating before use.

Steps: (1) unplug or remove the battery from the grinder. (2) Remove any old wheel and inspect the guard. (3) Align the wheel with the grinder’s spindle, ensuring the rotation direction is correct. (4) Thread the appropriate nut and tighten securely using the grinder’s wrench. (5) Reattach the guard and test rotation by hand before turning on the tool.

Wear safety glasses or a face shield, hearing protection, and gloves. Ensure the grinder’s guard is in place, use a firm grip, avoid applying excessive pressure, and inspect the wheel for cracks or damage before use. Do not use the wheel beyond its rated speed or on inappropriate materials.

Ideal for surface grinding and shaping of concrete, masonry, stone, brick, and asphalt surfaces. It’s commonly used for preparing surfaces, leveling uneven areas, and removing coatings or protrusions on masonry substrates.

Diamond cup wheels are typically suitable for both dry and wet grinding, depending on the grinder and application. If you’re cutting or grinding aggressively, light cooling with water can help manage heat and extend wheel life; always follow the tool’s guidelines and material requirements.

Look for signs of wear in the diamond segments (reduced grinding efficiency), cracks or damage in the wheel, glazing, or unusual vibration or wobble during operation. If any of these are present, replace the wheel to maintain performance and safety.
