Festool Saphir 5 inch 50 grit sanding disc is an aluminum oxide abrasive disc designed for aggressive stock removal, so it tackles heavy sanding where rapid cut is needed. The 50 grit rating delivers coarse cutting action, which helps strip thick or stubborn coatings instead of slowly polishing them. A 5 inch diameter works with common 5 inch hook and loop sanders, so it fits directly into many existing workflows. The disc uses a 9-hole pattern that supports dust extraction, helping keep the sanding surface clearer for more consistent cutting. Saphir is specified for heavy stripping jobs of hard, stubborn and thick coatings, so it is suited to demanding prep work on difficult surfaces. The disc is described as the ideal abrasive for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, giving a single disc that covers varied materials on the same job site.
This Festool 5 inch aluminum oxide sanding disc is sized for 5 inch sanders, so it integrates with tools built around that common pad size. The hook and loop backing attaches directly to hook and loop sanding pads, making installation and removal a simple press-on, peel-off action during work. A 9-hole disc pattern works with matching pad and dust extraction layouts, channeling dust away from the cutting surface. That pattern support helps maintain a more consistent scratch while sanding heavy coatings, since dust buildup can reduce cut. The combination of 5 inch size, hook and loop attachment and 9-hole layout aligns with professional sanding workflows focused on steady removal and disc change efficiency.
Saphir is for aggressive stock removal, so it fits tasks where material must be removed quickly rather than finessed. Heavy stripping jobs of hard, stubborn and thick coatings are a stated application, so it pairs with refurbishing or surface prep on tough finishes. The disc is called the ideal abrasive for heavy duty sanding of wood, which covers leveling or stripping built-up finishes on timber surfaces. The same disc is also noted as ideal for paint, allowing a single abrasive choice when taking failing or layered coatings off substrates. For plastics and fiberglass, the aggressive cut helps shape or strip without relying on multiple lighter passes. On composites, the disc addresses heavy duty sanding where mixed materials demand a strong abrasive. Concrete and steel are specifically named, so this disc reaches beyond typical woodworking into construction and metal prep environments where tough bases and heavy coatings are common.
This Saphir abrasive disc 493126 uses aluminum oxide abrasive, giving a durable cutting grain that supports repeated passes on hard, stubborn coatings without quickly dulling. The abrasive is described as incorporating a tear-resistant fabric backing, which reinforces the paper backed base so the disc resists tearing in extreme applications. That backing structure helps the disc stay intact under pressure, supporting consistent contact and predictable scratch patterns across the workpiece. The semi-closed coated design balances grit density with spacing, so the disc cuts aggressively while allowing swarf to clear between grains, which assists in maintaining cutting ability during long stripping runs. The synthetic resin bond holds the aluminum oxide to the backing, so grit remains attached as the disc encounters thick coatings on wood, paint, plastics, fiberglass, composites, concrete and steel. Together, these details support repeatable sanding performance on demanding removal tasks.
This Saphir disc is described as ideal for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, so it covers a wide range of surfaces on the same project.
The disc is 50 grit and Saphir is for aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings, so it serves coarse removal rather than fine finishing.
The disc is aluminum oxide on paper backed with a tear-resistant fabric backing and uses a synthetic resin bond, supporting longer life and stable grit hold in extreme applications.
The abrasive is semi-closed coated, giving dense grit coverage for aggressive cutting while allowing some spacing, which helps chips clear during heavy stock removal.
The disc is a hook and loop sanding disc, so it attaches to compatible pads using a hook and loop interface, enabling quick disc changes during sanding work.
The manufacturer part number is 493126, which uniquely identifies this Festool Saphir 5 inch 50 grit hook and loop 9-hole aluminum oxide sanding disc.
This Festool Saphir heavy duty sanding disc is defined by aggressive stock removal and heavy stripping jobs of hard, stubborn and thick coatings, so it aligns with demanding prep work. The 5 inch 9 hole sanding disc format integrates with hook and loop tools that use that size and pattern, supporting dust extraction during sanding. Aluminum oxide on paper backed construction with a tear-resistant fabric backing and synthetic resin bond is specified to handle extreme applications, so the disc fits rugged removal environments. The semi-closed coated surface is built for heavy duty sanding of wood, paint, plastics, fiberglass, composites, concrete and steel, giving one abrasive choice for varied substrates across the same project.
