15A478 - Walter XTRACUT 4.5-Inch Medium Grit QC Sanding Disc

High-Performance Ceramic Sanding with Rapid Changeover

The Walter 15A478 XTRACUT™ Quick-Change Sanding Disc represents a significant leap forward in abrasive efficiency for industrial metalworking. Designed for high-volume fabrication environments where downtime equals lost revenue, this 4-1/2 inch disc features Walter's innovative Quick-Change (QC) system. This mounting interface allows operators to swap out worn discs in seconds without the need for locking nuts or wrenches, streamlining the workflow and keeping production moving.

At the core of the XTRACUT™ performance is its advanced self-sharpening ceramic grain structure. Unlike conventional grains that dull and round over time, these ceramic particles micro-fracture to continuously expose new, sharp cutting edges. This mechanism ensures that the disc maintains a high stock removal rate throughout its entire lifespan, rather than tapering off performance as it wears. This specific "Medium" grit variant is engineered to strike an optimal balance between material removal and surface finish, making it an excellent choice for blending weld seams and preparing surfaces for subsequent finishing steps.

Heat management is critical when working with high-performance alloys and structural steel. The XTRACUT™ disc incorporates specialized cooling agents directly into the bonding matrix. These agents actively reduce friction and heat generation at the contact point, preventing thermal damage such as blueing, discoloration, or warping of the workpiece. This cool-cutting action extends the life of the disc and ensures the metallurgical integrity of the base material is preserved. When paired with the appropriate Walter rubber backing pad, this disc delivers a flexible yet aggressive solution for the most demanding grinding applications.
