Festool Saphir 5 inch sanding disc is a 36 grit hook and loop aluminum oxide abrasive designed for aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings. The coarse 36 grit profile cuts fast, which reduces time spent grinding through heavy finishes or leveling problem areas on demanding projects. The hook and loop back lets the disc attach quickly to a compatible 5 inch pad, which supports fast changeover between grits when moving from heavy removal to finer sanding stages. A 9-hole layout on the disc works with matching backing pads to draw dust away from the sanding surface, helping the abrasive stay effective longer during extended passes. The Saphir design targets extreme applications, giving installers and fabricators a dedicated option when lighter-duty discs load up too quickly or wear prematurely under tough conditions.
This 5 inch sanding disc uses a hook and loop backing, so it attaches to a compatible hook and loop sanding pad by pressing it into place, allowing quick disc swaps during staged sanding work. The 9-hole design in the disc aligns with matching 9-hole pads, creating channels for dust extraction as the abrasive cuts into the surface. This dust movement helps keep the cutting surface clearer, which supports a more uniform scratch pattern when working across wide panels or structural components. The round 5 inch format pairs with common compact sanders, allowing the same disc specification to move between multiple tools in a shop that share this pad size.
The Saphir disc is described as ideal for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, so it serves across carpentry, fabrication and repair environments. On wood, the aggressive 36 grit helps level high spots or remove thick finishes before finer sanding steps. On painted or coated surfaces, the disc targets stubborn and thick coatings, allowing technicians to strip back to a base material in fewer passes. Its suitability for plastics, fiberglass and composites supports tasks such as shaping or resurfacing panels where fast material removal is needed. On concrete and steel, the disc addresses tough substrates where a robust abrasive structure is important for sustained cutting performance.
The combination of aluminum oxide abrasive, synthetic resin bond and semi-closed coated structure defines how the disc cuts and wears, which influences repeatable outcomes across multiple workpieces. Aluminum oxide offers a hard cutting grain that maintains edge under extended use, so operators experience more consistent removal rates from one surface to the next. The synthetic resin bond secures the grit to the paper backed and fabric-reinforced base, supporting grain retention during demanding sanding tasks and helping the disc stay productive across longer runs. Semi-closed coated spacing leaves part of the backing exposed between grains, which influences how dust and removed material move away from the contact area and helps reduce clogging when taking down coatings or composite layers. The tear-resistant fabric backing is specified for longer life in extreme applications, so the disc structure resists tearing when working near edges or transitions that often stress the abrasive. Together, these elements support a workflow where the operator can rely on a consistent cutting feel across different materials named for this disc, from wood and paint through plastics, fiberglass, composites, concrete and steel.
The Festool Saphir disc is 5 inches in diameter and 36 grit, which delivers coarse, aggressive cutting suitable for fast stock removal and heavy stripping tasks.
The hook and loop backing lets the disc attach and detach quickly from a compatible pad, supporting fast grit changes during multi-step sanding or repair workflows.
The 9 hole disc pattern is designed to work with matching pads to channel dust away from the sanding surface, helping maintain cutting efficiency over longer passes.
