3M 00948 Clean and Strip Disc

SKU CH-35BG-G3ND9 MPN 00948

Abrasive disc with silicon-carbide non-woven fiber for paint, rust and coating removal

  • TypeSanders
  • Extra-coarse silicon-carbide strips paint fast
  • Non-woven fiber resists loading and smearing
  • 6-inch diameter covers large surface areas
  • 1/2-inch unthreaded hole fits many arbors
  • Rated for 4,000 RPM maximum speed

Application & Fit

The 3M 00948 Clean and Strip Disc is an abrasive accessory built for surface preparation on metal and other substrates. Its extra-coarse silicon-carbide grade and non-woven fiber backing make it suited for aggressive removal of rust, paint, scale and adhesives. The 1/2-inch unthreaded arbor hole fits compatible sanders and right-angle tools used in automotive restoration, metal fabrication and maintenance shops. It is not intended for fine finishing or precision polishing tasks.

Thermals, Noise & Power

As a non-powered consumable, the disc generates no electrical draw or acoustic signature of its own. Heat and noise levels depend entirely on the host tool and the material being worked. The maximum rated speed of 4,000 RPM sets a hard ceiling; running the disc faster risks structural failure and unsafe operating temperatures at the workpiece interface.

Build & Connectors

The black non-woven web is bonded to a fiber backing that resists smearing and loading during heavy stripping work. A 6-inch overall diameter provides broad contact area, while the 1/2-inch unthreaded center hole allows quick mounting on arbors or mandrels without tools. The smear-resistant formulation helps maintain cutting consistency through extended use, reducing the frequency of disc changes on large jobs.

Questions about this item

How do I fit the 6 in disc with its 1/2 in unthreaded hole onto my sander?

Slide the disc onto the arbor so the 1/2 in hole seats fully, then tighten the machine's lock nut or flange against the fiber backing; the step most people miss is checking that the disc sits flat before spin-up.

When will the silicon carbide non-woven material need replacing?

Replace the disc once the black extra-coarse surface glazes over or the fibers fray to the point that smear resistance drops and material removal slows noticeably.

What is the first limit I hit if I run the disc continuously at its 4,000 RPM maximum?

Heat buildup in the fiber backing becomes the limiting factor; sustained operation at the rated speed softens the adhesive bond and can cause the disc to delaminate.
