Runs SmoothLike all pads, the Standard Abrasives™ Holder Pad is a hard-face pad. In other words, it is flat and even without texture. The smooth face of the holder pad prevents it from causing bumps or extrusions on the abrasive disc.Different densities signal varying levels of flexibility of the holder pad. Soft-density holder pads are more pliable and responsive, so they're a good fit for finer-grade abrasives performing finishing and contouring. This medium-grade pad is good for discs that do general-purpose work. Firm-density holder pads are more rigid to support coarser abrasives that perform heavy stock removal. Discs and holder pads work together to get the job done.Altogether, Standard Abrasives™ Holder Pads allow for quick and easy disc attachment and removal, enhancing productivity and adding an extra level of efficiency and ease to your industrial applications.Quality Standard Abrasives™ Solutions for Industrial ApplicationsThe Standard Abrasives™ brand has supplied quality abrasives to the metalworking industry for over 50 years.
