The Evolution Diamond Demolition Disc Cutter Blade is the ultimate multi-material saw blade. It's packed with coarse-grain diamond cutting power to help you slice through masonry, rebar reinforced slab, mild steel and non-ferrous metals, as well as new or reclaimed wood. It will tackle any construction cutting task. Whether you're putting buildings up or knocking them down, you need a powerful saw that you can rely on, with a blade that outlasts the competition to make quick and easy cuts. It's built for long life, harsh working conditions and the toughest cuts. Offers up to 30x longer blade life than abrasive discs when cutting metal. Its diamond cutting edge is incredibly tough and can make over 1,000 cuts through steel. Cooling holes close to the edge expel heat to maintain optimum cutting performance. Cleaner & Safer: The steel body won't shatter, unlike abrasives, which can cause serious injury. Less dust, fewer sparks and less odour vs abrasive discs make this a safer cutting solution. This Evolution Multi-Material Diamond Demolition Disc Cutter Blade is compatible with our older 305mm/12in Disc Cutters and our current R300DCT and R300DCT+ models.
