Blue Zirconia Alumina Sanding Discs utilize quick snap on brass center holes which reduce vibration as they work. Flexible long lasting snap on discs made of Zircon, last up to three times longer than conventional abrasives.
The Zircon discs work on all non-ferrous metals like gold, silver and especially well with harder metals like platinum, stainless steel and titanium. These Blue discs are resin-backed for superior durability and aggressively cut and grind metals with a uniform file-like finish.
Note: Must be used with Snap on Mandrels to hold these.
