Bosch 4.5" Diamond Cup Wheel

- 4.5" (114 mm) diameter for balanced performance - Premium diamond grit construction for durability and cutting power - Optimized cooling channels to help dissipate heat - Universal fit compatible with most angle grinders - High grinding efficiency for faster material removal - Versatile across concrete, masonry, stone and other hard materials - Enhanced safety features to reduce operation risk - Long-lasting performance for demanding workloads

This wheel is designed for use with most angle grinders, providing a flexible, universal fit for a wide range of grinding tasks.

1) Ensure the grinder is powered off and unplugged. 2) Remove the existing guard if needed to access the mounting area. 3) Align the wheel with the grinder’s arbor and secure it with the appropriate flange and lock nut. 4) Tighten securely and reattach the guard. 5) Allow the wheel to run at low speed briefly before starting full operation to verify alignment. 6) Wear proper PPE and operate with a steady, controlled feed.

- Use a steady, moderate feed rate to prevent overheating - Avoid applying excessive pressure; let the wheel do the work - Ensure proper cooling and adequate ventilation during use - Keep the work surface clean of debris to prevent glazing or plugging of the diamonds - Inspect for cracks or missing segments and replace if needed

- Wear eye protection, a dust mask or respirator, hearing protection, and gloves - Ensure the grinder’s guard is in place - Secure the workpiece and maintain a stable stance - Avoid overheating and never force the wheel - Keep hands and clothing away from the rotating wheel at all times

- Surface preparation and grinding of concrete floors - Resurfacing and smoothing concrete, stone, and masonry surfaces - Preparing floors for coatings, sealants, or toppings - Grinding irregularities and achieving a smoother finish on tough materials
