Festool Saphir 5 inch sanding disc is an 80 grit hook and loop, 9-hole aluminum oxide disc designed for aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings. The durable aluminum oxide abrasive on this disc delivers heavy duty sanding performance, so material removal stays consistent across demanding surfaces. Its paper backed design supports the abrasive while working with the hook and loop attachment, which helps with fast disc changes during staged sanding. The disc is part of the Festool Saphir line, so it is positioned for extreme applications where rapid removal is more important than fine finishing. The 9-hole layout works with compatible sanders that use a matching pattern to move dust away from the abrasive surface, helping the disc stay effective while material is being stripped.
This Saphir 5 inch 80 grit disc uses a hook and loop backing, so it mounts to compatible hook and loop sanding pads by pressing the disc onto the pad. The 9-hole layout is designed for pads that share the same pattern, so aligning the holes allows dust extraction through the disc while sanding. The paper backed construction supports the abrasive layer against the pad surface, helping the disc stay flat while removing hard, stubborn coatings. Using the specified 5 inch diameter keeps the edge of the disc aligned with matching backing pads, which supports even contact and consistent removal over the full sanding face.
This Festool Saphir disc is specified for aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings, so it is suited to tasks where fast removal of material is the priority. The abrasive is described as the ideal abrasive for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, so the same disc type can be applied across shop-built components and site materials. On wood or paint, the 80 grit cut removes heavy build-up or tough finishes to reach a sound surface for further preparation. On plastics and fiberglass, the disc handles shaping or stripping thick resins where a strong bite is needed. On composites, concrete and steel, the aluminum oxide grain supports heavy duty sanding where surfaces are dense or coated, so large areas of stubborn coatings can be brought down efficiently.
The Saphir disc uses aluminum oxide abrasive, which is specified for heavy duty sanding in this design, so the grain choice supports the aggressive stock removal described. The abrasive is bonded with synthetic resin and is semi-closed coated, giving a balance between cutting surface and spacing, so the disc can both bite into thick coatings and manage loading in extreme applications. A tear-resistant fabric backing is incorporated with the durable aluminum oxide abrasive for longer life in extreme applications, so the disc structure resists tearing when used on hard, stubborn and thick coatings. This backing support helps maintain a consistent sanding face, reducing interruptions from disc failure during demanding stripping work. The combination of the 5 inch diameter, 80 grit, hook and loop backing, 9-hole pattern, aluminum oxide abrasive, synthetic resin bond, semi-closed coating and fabric-reinforced backing all contributes to a disc that stays effective across repeated heavy removal passes on wood, paint, plastics, fiberglass, composites, concrete and steel.
This Festool Saphir disc is designed for aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings, so it suits demanding removal tasks rather than fine finishing.
This disc is specified as ideal for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, giving one abrasive option for many shop and site materials.
The hook and loop backing lets the disc attach to compatible pads by pressing it on, so disc changes between stages or when worn are quick during continuous sanding.
The 9-hole layout is designed to match multi-hole pads so dust can move through the disc, helping the abrasive stay clearer and maintaining cutting performance while sanding.
The semi-closed coated aluminum oxide abrasive, bonded with synthetic resin, combines strong cutting action with spacing that helps manage loading in extreme sanding applications.
The tear-resistant fabric backing works with the durable aluminum oxide abrasive to provide longer life in extreme applications, reducing disc failure during heavy stripping passes.
The Festool Saphir 5 inch 80 grit hook and loop, 9-hole aluminum oxide disc with tear-resistant fabric backing is built for aggressive stock removal on hard, stubborn and thick coatings. Its design targets heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, so the same disc type can stay on the sander across varied tasks. When the job calls for a disc from the Saphir line that prioritizes rapid removal in extreme applications, this Festool 493127 option aligns with that role.
