The OX Professional MPS 9 inch Turbo Diamond Blade is a turbo rim diamond blade for cutting masonry, concrete, brick, pavers and similar hard materials. At 9 inches (about 230mm) in diameter, it is a multi purpose blade designed to cut across a range of building materials with one blade, and its larger size suits bigger cutting jobs. It features a 12mm superfast turbo rim for fast, smooth cutting and a long working life. The blade is reinforced with an extra secure dual centre flange and a unique cool fast design that helps manage heat during cutting. In use it runs semi transparent and cuts out much of the vibration associated with conventional diamond tools, giving smoother, more controlled cutting. It has been safety and vibration tested to meet and surpass relevant standards, making it a dependable choice for professional site work. This is a larger diameter blade, so always confirm it is rated for your tool and follow safe operating practice before you start.
