Engineered for deep cuts in heavy-duty masonry, this 180 mm (7 inch) turbo diamond blade is perfect for thick concrete slabs and large blocks. The turbo rim provides a fast, aggressive cut with a smooth finish that minimizes chipping. A tall 10 mm segment height offers a long and productive service life. This blade uses a standard 22.23 mm (7/8 inch) arbor to fit 180 mm and 230 mm angle grinders.
