The 10-SEGMENT grinding disc is the most versatile disc on our shelves. This grinding disc can be used on multiple variables of concrete, wet or dry. The 10-SEGMENT grinds smooth with a subtle scratch pattern making this the ideal tool to prepare the concrete substrate for surface finishing without worrying about deep scratches others tools will leave. The 10-SEGMENT grinding disc is universal and works on most if not all rotary floor machines. Its high segments (8mm) provide the most square foot coverage at the lowest cost.
