Black Rock Diamond Cutting Disc Segment 4.5"

It features a segmented diamond coating for fast cutting, a long-lasting blade life, a custom alloy steel core for strength and reduced vibrations, Core-Cool technology louvers for rapid heat dissipation, and a break-resistant plastic construction to improve safety.

Tile, marble, granite, ceramic, concrete, stone and asphalt are all suitable materials for this 4.5" segment blade.

Core-Cool Technology uses louvers in the core to dissipate heat quickly, helping maintain cutting efficiency and extend blade life during heavy-duty use.

Ensure your angle grinder accepts a 4.5" disc, mount the blade securely on the spindle with the proper nut, and fit the appropriate guard. Always wear PPE, use a steady feed, avoid excessive pressure, and follow your tool’s maximum RPM guidelines.

The blade has a 4.5-inch diameter with a segmented diamond coating electronically welded to a custom alloy steel core. It’s designed for heavy-duty cutting and reduced vibration, with safety features built in to minimize risk during use.

It incorporates a break-resistant plastic component to reduce disc breakage and protect the user from flying shards, enhancing overall cutting safety.

Segmented blades like this one typically cut faster and dissipate heat more effectively on tough materials, while continuous-rim blades tend to offer smoother cuts but may heat up more quickly and clog under heavy use.

Use a steady, moderate feed rather than forcing the blade, keep the workpiece stable, allow the blade to cool during longer cuts, and choose the correct speed within the tool’s rated range to avoid overheating.
