3M XTRACT SANDING DISC Clean sanding discs combine proven 3M abrasive technology with a breakthrough surface configuration that delivers up to two times the life of standard high-performance discs. At the same time, they allow better dust extraction by tool-mounted vacuum collection systems, to help keep your workplace cleaner, more comfortable, and more productive. - The medium, C-weight backing of these discs provides more durability and faster cutting than A-weight discs. An open coat and stearate coating extend disc life and prevent loading. - Aggressive, fast cutting general purpose aluminum oxide abrasive - Last twice as long as standard abrasive discs without holes - Less disc loading - Improved dust extraction; less
clean-up.
