3M 268L PSA Sanding Disc 5" 80 Micron Aluminum Oxide Microfinishing Film No Hole Bulk-25 51144139149
Description
3M 268L Aluminum Oxide PSA Sanding Disc Purpose
3M 268L 5" PSA 80 Micron No Hole Aluminum Oxide Sanding Disc on Film uses aluminum oxide abrasive on a film backing to cut surfaces while maintaining a controlled scratch pattern, which helps produce predictable finishing results on production jobs. The 5 inch diameter works over common sanding pads, supporting coverage on flat areas without feeling bulky in hand-guided work. Its 80 micron grading ties directly to a defined cut rate and finish level, which helps repeat sanding steps in a shop process. The pressure sensitive adhesive backing secures the disc to the pad during use, so it stays in place through passes instead of shifting. The no hole layout presents a continuous abrasive surface, which gives full face contact for each stroke across solid surfaces. As part of the 3M 268L line of abrasives, this disc is built for industrial and occupational sanding workflows.
Key Abrasive Disc Details For Shop Work
- The 80 micron aluminum oxide abrasive focuses on a specific cut level, so operators can match this disc to a known sanding stage and keep finish quality consistent from part to part.
- The 5 inch disc size spans typical sanding pads effectively, helping cover material efficiently while still allowing controlled edge work on panels, tops, and similar surfaces.
- The film backing supports the premium micron graded mineral, helping the abrasive stay flat against the work so the scratch pattern remains uniform across the contact area.
- The pressure sensitive adhesive backing bonds the disc to the backup pad during use, which reduces disc movement and supports steady sanding contact across each stroke.
- The no hole disc face presents uninterrupted abrasive coverage, which keeps every part of the sanding area available for cutting on solid surface applications.
PSA Film Disc Details For Installation And Use
The pressure sensitive adhesive backing on this 5 inch 3M 268L disc presses directly onto a compatible sanding pad, which allows quick disc changes between grit stages in a production sequence. Because the disc uses an 80 micron aluminum oxide abrasive, it fits into sanding systems that define steps by micron rather than traditional grit ranges. The film backing supports the premium micron graded mineral so it stays flat on the pad, which helps the installer hold a consistent sanding angle along edges and broad surfaces. With its no hole design, the entire face can be used to contact the workpiece, which supports full coverage sanding passes on solid surface materials and similar substrates.
How This 3M Abrasive Disc Fits Shop Work
Using The 5 Inch 80 Micron Disc On Solid Surface
This 3M 268L 5" PSA 80 Micron No Hole Aluminum Oxide Sanding Disc on Film is described as excellent for solid surface finishing, so it suits shop work on countertops, panels, and similar fabricated parts. The aluminum oxide mineral delivers the cutting action needed to refine machine marks on these surfaces, helping move them toward a uniform finish. Because the mineral is premium micron graded, each disc maintains a consistent particle size, which means the scratch pattern stays even from the center to the edge of the pad. The no hole construction keeps the entire 5 inch face available for contact, which supports broad passes across flat solid surface areas and reduces striping from interrupted abrasive zones.
Why The Film Backing And PSA Matter For Results
The high strength polyester film backing used on this 3M 268L disc supports the abrasive layer so it stays flat against the backup pad, which helps each pass leave an even, controlled scratch pattern rather than random deep cuts. That backing works with the premium micron graded aluminum oxide to deliver a precise and consistent uniform finish, which simplifies later stages in a finishing schedule. The pressure sensitive adhesive bond holds the disc securely to the pad, helping prevent shifting that could track or swirl the surface. Because 3M notes that 268L abrasives are fast cutting while providing a precise uniform finish, this balance allows installers and fabricators to move material efficiently while still targeting the surface quality demanded in industrial and occupational solid surface finishing.
Installer Questions About This 3M 268L Sanding Disc
What type of abrasive does this 3M 268L disc use?
This 3M 268L disc uses aluminum oxide abrasive on a polyester film backing, which provides cutting power with a controlled, uniform scratch pattern suited to industrial finishing steps.
How does the 80 micron grading affect the finish?
The 80 micron grading sets a defined particle size, so the disc delivers a predictable cut and finish level, which helps keep sanding steps repeatable in a shop process.
Why choose a 5 inch PSA disc with no holes?
The 5 inch no hole disc provides full-face abrasive contact on the pad, supporting broad, even passes over solid surfaces while the PSA backing keeps the disc firmly attached.
What backing material supports this abrasive disc?
This disc uses a high strength polyester film backing, which keeps the abrasive layer flat and stable, helping maintain a precise and consistent uniform finish across the workpiece.
How is this disc positioned for solid surface finishing?
3M describes 268L abrasives as excellent for solid surface finishing, so this disc fits tasks such as refining machine marks and preparing fabricated solid surface components.
Who is this 3M abrasive disc intended for?
This 3M industrial and occupational product is intended, labeled, and packaged for trained industrial and occupational customers for workplace use, not for consumer sale or use.
Selecting This 3M 268L Disc For Your Work
