The Bosch PRO A30S BF Flat Metal Cutting Disc in 300mm is the largest disc in the range, designed for use with high-powered cut-off machines and suited to the most demanding metal cutting applications — including heavy structural steel, large box sections, and high-volume fabrication work. Premium aluminium oxide grains are embedded in a phenol resin matrix alongside functional fillers, ensuring the disc can cope with the increased heat and load generated during large-scale cutting. The reinforced fibreglass net maintains structural integrity throughout, providing the stability and safety required when working with a disc of this size and capacity.
