These grinding disc seem to be just as good as the higher priced name brand units. Same results at a quarter of the price, I'm in!

The LAUCO 3" Quick-Change Discs are engineered for heavy-duty, aggressive surface preparation tasks. This bulk pack contains 25 discs at Grit 36, delivering the coarse-cut performance required for rapid material removal, paint stripping, shaping, and grinding across demanding metal and wood applications.
These professional-grade discs are built with Premium Zirconia Abrasive Grains, offering significantly superior durability and a faster, more aggressive cut rate compared to standard aluminum oxide. The robust construction ensures they remain sharp and effective for longer, maximizing your productivity on tough jobs.
Crucially, each disc features an Active Grinding Aid. This innovative component works by reducing friction and heat buildup during use, effectively preventing premature loading or clogging of the disc surface. This heat reduction is essential when working with sensitive materials, guaranteeing excellent performance and extended disc life on heat-sensitive alloys such as stainless steel, nickel alloy, and cobalt alloys.
Designed for maximum versatility, the discs feature the standard male Type R Quick Roll On / Roll Off fastening system. This universal quick-change design ensures swift, tool-free attachment to any 3-inch backing pad. The backing pad can then be mounted to a standard ¼-inch power drill, air grinding tool, or die grinder, making these discs immediately compatible with your existing workshop equipment for seamless integration into any auto body shop, industrial, or metalworking environment.
