The Festool 204315 S 105/4 Fast-Cutting Jigsaw Blades are a 5-pack of wood-cutting jigsaw blades built for fast, general-purpose cuts in common sheet goods and lumber. This is a jigsaw blade designed for fast wood cutting. Model Number 204315. If you run a Festool jigsaw or another professional saw that accepts a T-shank blade, this set gives you a practical blade for everyday work where speed matters.

The big story here is the tooth pattern. Festool uses cross-set teeth to keep the cut moving quickly while still leaving a clean enough edge for a wide range of jobsite and shop work. With a 6 to 7 teeth per inch pitch and a 3/16" (4 mm) spacing, these blades are aimed at faster cuts rather than ultra-fine finish work. That makes them a solid pick for rough sizing, general carpentry, cabinet breakdown, and routine plywood or softwood cuts where you want progress without beating up the material.

The 4-1/8 inch blade length and 2-3/8 inch maximum workpiece thickness tell you where this blade fits best. It has enough length for common wood stock and sheet material, but it is still easy to control in a handheld jigsaw. For most users, that means one blade that can handle a lot of normal cutting tasks in softwood, hardwood, melamine, veneered plywood, and chipboard without overthinking the setup.

Festool lists these as a WOOD BASIC blade, and that is exactly the right way to read them. They are not trying to be a specialty scroll blade or a fine-finish laminate blade. They are meant to be the blade you grab when you need a reliable, value-minded wood-cutting accessory that gets through material quickly and works across several common jobsite materials. The high carbon steel construction fits that role well for wood and wood-based products.

The T-shank interface is important because it broadens where these blades can be used. Festool specifically lists compatibility with PS 300, PSB 300, PS 400, PSC 400, PSBC 400, PSB 400, PS 420, PSB 420, PSC 420, and PSBC 420 jigsaws. Beyond that, the universal T-shank format is widely used across professional jigsaw platforms, so these blades are easy to keep in rotation if your saw accepts that blade style.

If you care about practical results, this is the kind of blade that earns its keep by being useful on a lot of cuts instead of perfect on one. It is a good fit for carpenters, remodelers, installers, cabinet guys breaking down panels, and serious DIY users who want a dependable Festool wood jigsaw blade for daily work. If your priority is fast cutting in wood-based materials with a straightforward T-shank setup, the Festool 204315 S 105/4 Fast-Cutting Jigsaw Blades make a lot of sense.
