Arbor-Mount Sanding Discs
Fit these discs over your tool’s arbor. They require a backup pad (sold separately).
Fast-Cutting Nylon Mesh Cushioned Arbor-Mount Sanding Discs
Nylon mesh is embedded with precision-shaped ceramic alumina, which cuts through hard metals like stainless steel faster than other forms of ceramic alumina because of its sharp, outwardly pointed grit. The grain particles continually fracture to produce new, sharp cutting edges while maintaining their specially engineered points and angle. The design also reduces heat generation while sanding, which prevents the grit from wearing down. These discs are also good for sanding steel and soft metals.
When you need to achieve a more consistent finish, choose nylon mesh discs over paper- or cloth-backed discs. The mesh flexes to compensate for uneven sanding pressure as you sand. Fit these discs over your tool’s arbor. They require a backup pad (sold separately).
Extra coarse grade is for heavy cleaning and stripping.
Coarse grade is for light deburring and removal of heavy rust and surface imperfections.
Medium grade is for cleaning, blending, and rust removal.
Fine grade is for light cleaning, blending, and finishing.
Very fine grade is for light scratch removal, finishing, and polishing.
