SAFETY: Good thermal conductivity can prevent burns and breakage of the workpiece, which greatly improves the processing quality. ENERGY SAVING: Good grinding performance can reduce grinding performance and energy consumption. MAIN FUNCTION: Effective grinding of difficult-to-machine materials such as ceramics, stone, concrete, etc. Can be used with a sharpener and knives. ADVANTAGE: High wear resistance makes the diamond grinding wheel a tool that satisfies both high performance and precision machining. CAUTION: Avoid dust, wear goggles, earplugs, and a good dust mask when using it. Description: The diamond grinding wheel has strong abrasive grain, long service life and low abrasion, which means it can make full use of its wear resistance and excellent grinding effect. It is an ideal tool for grinding brittle materials such as ceramics, stone, concrete, etc. Features: Material: Diamond. Workmanship: Sintering Color: Red Outer Diameter: 100 mm / 3.94 inch.
