The Festool 578098 OSC-SORT/5 5-Piece Oscillating Saw Blade Set is a multi-tool accessory kit built for the Festool OSC 18. This is an oscillating saw blade set designed for cutting, trimming, flush sawing, plunge cutting, and scraping across a wide range of jobsite materials. Model Number 578098. If you use an oscillating multi-tool for punch-list work, remodel cuts, or tight-space detail work, this set covers the jobs that come up most often without making you buy blades one at a time.

What matters here is the mix. Festool includes five different accessories so the set can move from wood cutting to metal cutting to surface prep. According to the product data, the set is built to handle wood, coated wood, wood-like products, solid wood, painted wood, composite materials, plasterboard, non-ferrous metals, plastics, abrasive materials, and durable adhesive coatings. That makes it a strong fit for remodeling, finish corrections, trim work, drywall cut-ins, and repair work where material changes from one cut to the next.

The included blade selection is practical, not padded. You get a carbide saw blade for tougher material contact, two universal Bi-Metal style blades for broader cutting tasks, a dedicated scraper blade for removing tile cement, old paint, and glue residue, and a wood saw blade for cleaner wood-focused work. In real use, that means the set can handle flush cutting nails or hardened screws, trimming door casing, plunge cutting drywall, and scraping off stubborn residue with fewer compromises than a single-blade purchase.

Festool also built this set around the Starlock accessory system. The listed performance class is Starlock, Starlock Plus, and Starlock Max, which matters because it broadens compatibility across matching oscillating multi-tool interfaces while supporting quick, tool-free blade replacement on compatible machines. On the job, that is the difference between staying in rhythm and wasting time with accessory changes when you switch from a plunge cut to scraping or from wood to metal.

For jobsite practicality, this is the kind of set that earns its keep in service work and remodeling. Oscillating tools are usually the answer when a bigger saw cannot fit, when a cut has to start in the middle of the material, or when you need to trim something in place without tearing apart surrounding finishes. Having a blade set that is ready for drywall, plastics, composites, fasteners, and coatings makes the OSC 18 a lot more useful day to day.

Compatibility is straightforward. Festool lists this set as suitable for the OSC 18, and the accessories use the Starlock family interface. If you already run the Festool cordless oscillating multi-tool, this is an easy way to cover common cutting and scraping tasks with one organized blade assortment instead of buying separate replacements as each job comes up.

Who should buy it? This set makes the most sense for remodelers, finish carpenters, installers, maintenance crews, and serious DIY users who actually use an oscillating multi-tool across different materials. If your work includes trim modifications, drywall openings, hardware cut-outs, metal flush cuts, or glue and mortar cleanup, the Festool 578098 OSC-SORT/5 5-Piece Oscillating Saw Blade Set is the kind of accessory kit that saves time because it is built around the tasks people really use a multi-tool for.
