SAFETY: Good thermal conductivity can prevent burns, cracking of the workpiece, greatly improving the processing quality. ENERGY SAVING ： Good grinding performance reduces grinding power and energy consumption MAIN FUNCTION: Efficient grinding of difficult-to-machine materials such as ceramic, stone, concrete, etc. Can be used with a grinder and knives. ADVANTAGE: The high resistance to wear makes the diamond wheel a tool capable of satisfying both high efficiency and precision machining. CAUTION: Avoid dust, please wear safety glasses, earplugs and a good dust mask when using it. Description: The diamond wheel has a strong abrasive grain, long life and low abrasion, which allows it to fully play on its wear resistance and excellent grinding effect. It is an ideal tool for grinding co.ukagile materials such as ceramic, stone, concrete, etc. Features: Material: diamond Finishing: sintering The color red Outside diameter: 100mm / 3.94inch Bore diameter: 22.23mm Thickness: 4.5mm /
