Outstanding lifespan in metal! No splintering, no odor emissions, no expiration date. Cutting metals like steel and cast iron has always been challenging with bonded cutting discs. Many users are familiar with the smell of burnt material from bonded discs that actually burn away while cutting. With the Expert Diamond Metal Wheel, that odor is a thing of the past – just like the regular trips to the store to buy new bonded cutting discs. For craftsmen and construction workers who no longer want to spend money on bonded discs, the Bosch Expert Diamond Metal Wheel X-LOCK diamond cutting disc offers a completely new way to cut metal. Exceptionally robust cutting edge with Bosch Diamond Technology.
