Description
The Kratos Vacuum Brazed 4" Flat Cup Wheel is a heavy-duty grinding tool designed for aggressive stock removal on granite, marble, quartz, and other hard stone materials. Manufactured under the Kratos brand, which is recognized in the professional stone tooling market for durable, high-performance abrasive products, this flat cup wheel delivers reliable material removal in demanding fabrication and restoration applications. Available in Coarse and Fine variants, it provides the right abrasive grade for each stage of the grinding process.
Vacuum brazing is a premium manufacturing process that bonds diamond crystals to the tool matrix at extremely high temperatures in a controlled vacuum environment. This process creates a stronger, more uniform bond between the diamond layer and the steel body compared to conventional sintered or electroplated tools. The result is a cup wheel that maintains its cutting performance longer, resists premature segment loss, and handles the heat and mechanical stress of continuous stone grinding applications.
The 4-inch diameter flat cup wheel is compatible with standard 4-inch angle grinders, making it a versatile tool for both shop and field use. Whether you are shaping stone edges, removing old adhesive from surfaces, or performing restoration grinding on existing installations, the Kratos Vacuum Brazed Flat Cup Wheel delivers the power and consistency professional fabricators and restoration contractors demand. Choose Coarse for initial shaping and aggressive removal, or Fine for finishing and surface preparation prior to polishing.
