The Festool 205774 ALUMINIUM/PLASTICS HW 168x1.8x20 F/FA 52 168mm 52T Saw Blade is a 168 mm circular saw blade made for aluminum, plastics, and non-ferrous metals. This is a circular saw blade designed for clean, controlled cutting in aluminum panels, profiles, acrylic, PVC, and similar sheet or profile materials. Model Number 205774. If you are running a Festool plunge saw or table saw in these materials, this blade matters because the geometry is built around cut quality, low wear, and predictable results instead of rough fast cuts.

The big story here is application-specific tooth geometry. Festool uses 52 fine-grain carbide teeth with a flat tooth and variable chamfer pattern, plus a negative 5 degree chip angle and 20 degree relief angle. In plain terms, that means this blade is tuned to stay controlled in harder, more brittle, or grabby materials like aluminum composite panel, acrylic glass, copper, and brass. That setup helps reduce edge damage and keeps the cut looking more finished right off the saw.

The 168 mm diameter, 20 mm arbor, 1.8 mm cutting width, and 1.2 mm blade thickness are a direct fit for the Festool platforms it is built around. Festool also calls out that the cutting angle and tooth shape are adapted to both the application and the machine. That is not filler. A blade that is matched to the saw tends to track better, cut cleaner, and put less unnecessary load on the tool, especially when you are trying to keep a straight line in panel material or maintain a clean visible edge.

Material quality is a real part of the value here. The blade body is made from high-quality steel and the teeth are made from fine-grain carbide. That combination is what gives you the mix you want on this kind of blade: enough durability to hold up in demanding work, and enough edge retention to keep cut quality from falling off too fast once the blade sees regular use. Festool also highlights the reduced cutting width, which helps the blade work faster and for longer by removing less material per pass.

On the job, this blade is aimed at the kind of work where a sloppy edge costs time. It is a strong choice for cutting aluminum composite panels, aluminum profiles, twin-wall sheeting, phenolic-resin-bonded fibers and fabrics, PVC, acrylic glass, and other hard or fiber-reinforced plastics. It is also called out for non-ferrous metals such as copper and brass. If you move between trim panel work, sign material, cladding, fabrication, and finish-sensitive sheet goods, that range matters.

Compatibility is straightforward. The Festool 205774 blade is suitable for the Festool TS 60 K, TSV 60 K, and CSC SYS 50. That makes it a purpose-built accessory for users already in that saw platform, not a generic blade you hope works well enough. Festool also uses color coding on the blade to help identify the right blade for the material category faster when you have several blades in rotation.

Who should buy it? Contractors, installers, remodelers, fabricators, and serious DIY users who regularly cut aluminum or plastic-based materials with Festool saws. If most of your work is wood framing, this is not the blade to leave on all day. But if your work includes aluminum trim, composite panels, acrylic sheet, or other non-ferrous materials where edge quality matters, this is the right blade for the job and a better call than trying to force a general wood blade to do specialty work.

Buy the Right Blade and the Cut Gets Easier

The Festool 205774 ALUMINIUM/PLASTICS HW 168x1.8x20 F/FA 52 168mm 52T Saw Blade is the kind of accessory that saves you from fighting the material and cleaning up rough edges afterward.

• Who it's for: Festool TS 60 K, TSV 60 K, and CSC SYS 50 users cutting aluminum composite, aluminum profiles, acrylic, PVC, and other non-ferrous or plastic-based materials.
• Why it stands out: The tooth geometry is purpose-built, the carbide teeth are there for long life, and the 52-tooth layout is aimed at cleaner finish quality instead of rough production cuts.
• Worth knowing: This is a specialty blade, not an all-day wood blade. If your work is mostly framing lumber, wrong blade. If your work is panel, trim, or fabrication material that needs a clean edge, this is the smart buy.

• What saws is this blade made for? It is suitable for the Festool TS 60 K, TSV 60 K, and CSC SYS 50.
• What materials is this blade designed to cut? Festool lists aluminum panels and profiles, aluminum composite panels, perspex, hard and fiber-reinforced plastics, PVC, acrylic glass, and non-ferrous metals such as copper and brass.
• What size is the blade? The blade diameter is 168 mm with a 20 mm arbor hole.
• How many teeth does it have? It has 52 teeth.
