The Zirconia Type R Roloc quick-change cloth disc delivers powerful performance for all of your most demanding tasks. Grind through difficult exotic alloys and tackle high-pressure applications with ease thanks to this disc's durable, waterproof Y-weight polyester backing. A semi-open coat diminishes loading, so you can flawlessly deburr and blend soft metals, such as brass, bronze, and carbon steels, as well as delicate wood surfaces. The disc's premium zirconia-plus grain remains sharp to consistently produce aggressive cuts, and it boasts an up to 30 percent longer life span than similar discs from competitors.

Key Performance Benefits
- Self-Sharpening Grains: Zirconia alumina is a synthetic abrasive that micro-fractures during use, continuously exposing new, sharp cutting edges. This ensures a consistent cut rate and a lifespan up to three times longer than standard aluminum oxide discs.
- High Stock Removal: Designed for aggressive grinding, these discs excel at removing welds, rust, and heavy scale. They perform 25% better than conventional materials in rapid stock removal tasks.
- Heat & Pressure Resistance: Zirconia is significantly tougher and more heat-resistant than aluminum oxide. Many variants include a grinding aid (top coating) that reduces friction, prevents workpiece discoloration, and keeps the disc cool during intensive sessions.
- Durability Under Load: They feature reinforced cloth backings (often X or Y-weight) that provide the stiffness needed for medium to high-pressure applications without tearing or delaminating.
