This Diamond Grit Swing Blade is 3×2-3/16 and a professional grade quality accessory for scraping or cutting concrete, brick, and ceramic material with the Oscillating Multi Tool. Great for removing grout, cutting ceramic tile and thinset, cement board and brick and other masonry applications. Works with universal arbors.
Please note: This blade is meant more for use on ceramic tile and NOT porcelain tile as porcelain is much harder to cut. You can still use this diamond grit swing blade to chase cracks in porcelain tile but it may not remove complete pieces of porcelain, depending on the thickness of the tile.
