48H524 - Walter TOPCUT+ 5 Inch 24 Grit Resin Fiber Disc

Heavy-Duty Stock Removal with Walter TOPCUT+

The Walter TOPCUT+ Resin Fiber Disc (48H524) is engineered for the most demanding industrial grinding applications. Designed with a premium Zirconia Alumina grain blend, this 5-inch disc delivers exceptional bite and rapid stock removal rates, making it the go-to choice for metal fabricators and MRO professionals dealing with heavy weld seams and structural steel.

What sets the TOPCUT+ apart is its advanced thermal management. The disc incorporates active cooling agents directly into the resin bond, which significantly lowers the grinding temperature. This feature is critical when working on heat-sensitive materials like stainless steel, as it helps prevent heat discoloration (blueing) and warping of the workpiece. The 24-grit composition is particularly aggressive, ideal for the initial stages of surface preparation where speed and material removal are paramount.

Durability is a core component of the Walter 48H524. Built on a tough, vulcanized fiber backing, it resists tearing and maintains its shape even under high pressure. This structural integrity ensures consistent performance from the first spark to the last, reducing the frequency of disc changes and thereby increasing overall shop productivity. Whether you are beveling plates, leveling welds, or removing heavy corrosion, the TOPCUT+ provides the reliability required for continuous industrial use.

Key Applications

• Weld Removal: Rapidly grinds down heavy weld beads on structural steel.


• Beveling: Prepares metal edges for welding with aggressive material removal.


• Deburring: Removes sharp edges and heavy burrs from cut metal parts.


• Surface Blending: Smooths out rough surfaces on cast iron and steel.
