Rapid Stock Removal with Grinding Aid
Our Standard Abrasives Quick Change Zirconia Pro 2-Ply Disc was engineered for rapid stock removal on medium to high-pressure applications. Its reinforced Y-weight backing provides the necessary robustness for the demands of grinding and deburring, while the grinding aid enhances cut and helps prevent part discoloration on stainless steel and other exotic alloys.
Quick Change Convenience
We offer this disc in a range of sizes, grits and quick change sanding systems. Quick change discs allow tool-free swap outs, maintain secure attachment at high speeds, and save operators time when switching discs between grades or applications.
Choose the disc compatible with your TP, TR, or TS holder pad. The TP system features a snap-on/snap-off nylon fastening hub. TR discs have a nylon threaded hub that easily mounts to TR or 3M Roloc type holder pads with a turn of the wrist, and the TS system has a metal hub that attaches to its holder pad with a simple twist.
Extra Sharp Alumina Zirconia
Alumina Zirconia fractures frequently to continually produce fresh sharp points and delivers a faster cut-rate than aluminum oxide. A man-made mineral, it was developed for heavy stock removal and high pressure grinding.
Our Zirconia Pro disc is also available in a PSA version in larger sizes. The versatile portfolio of Standard Abrasives Discs helps to ensure that operators will find a disc that is well-suited to their project needs and applications.
