Engineered for a fast, clean cut, this 106 mm (approx. 4 inch) turbo diamond blade is perfect for concrete, brick, and pavers. The continuous turbo rim reduces chipping and vibration for a smoother finish and is highly effective for dry cutting. A 7.5 mm segment height provides a durable service life for general-purpose tasks. This blade uses a 20 mm arbor and is compatible with many small angle grinders.
