Lasts up to 50 times longer than a Bosch cutting disc. Cutting metals such as steel and cast iron has always been challenging for angle grinder discs. Many workers are familiar with the chemical smell of bonded discs that literally burn away while cutting. With the EXPERT Diamond Metal Wheel, that smell is a thing of the past—just like frequent trips to the store to buy new metal discs. The EXPERT Diamond Metal Wheel, featuring Bosch Diamond Technology, offers diamond grains of optimal quality that are bonded to a steel body. This extremely hard edge lasts significantly longer than even the best bonded discs. It can effortlessly cut a variety of ferrous and non-ferrous metals. It does not shatter when dropped, produces no chemical smell or additional dust during cutting, and maintains a consistent cutting depth and speed throughout its long lifespan. For craftsmen and construction workers who no longer want to spend money on bonded discs, the Bosch EXPERT Diamond Metal Wheel offers a completely new way to cut metal. It has a 16 mm bore diameter for standard angle grinders with a clamping nut.
