The Festool 202958 DIA 160x2,2x20 F4 Abrasive Materials Diamond Saw Blade is a 160 mm diamond saw blade for cutting fiber-cement and other abrasive sheet materials. This is a diamond saw blade designed for precise cutting of fiber-cement material with Festool track saws. Model Number 202958. If you are using a TS 55 REQ or TSC 55 REB and need a blade that holds up to cement-bonded or gypsum-bonded boards, this is the purpose-built option instead of burning through standard wood blades.

What matters here is that this blade is not trying to be an all-around circular saw blade. It is made for abrasive materials that chew up conventional teeth fast. The 160 mm diameter, 2.2 mm cutting width, 20 mm arbor hole, and 4-segment diamond design are tuned for controlled cutting in fiber-cement applications. That means more consistent cuts, less wandering, and better performance in materials that are tough on ordinary carbide blades.

Festool also built this blade around its plunge track saw platform, which is why the fit matters so much. Paired with the TS 55 REQ or TSC 55 REB, you get the kind of straight-line cutting and repeatability that siding installers, remodelers, and finish crews need when breaking down cement board accurately. The negative 5 degree chip angle helps keep the cut controlled in brittle, abrasive material instead of acting overly aggressive.

On the job, dust control is a big deal with fiber-cement. Festool specifically notes minimal dust when this blade is used together with Festool CT mobile dust extractors. That does not just make the workspace cleaner. It helps visibility at the cut line and makes indoor or occupied-space work easier to manage when you are trimming boards, fitting panels, or making repeated cuts throughout the day.

From a durability standpoint, the blade material is diamond, which is the right answer for abrasive products where tooth wear is the real problem. If your work regularly involves cement-bonded board, gypsum-bonded chipboard, or fiberboard, using the correct abrasive-material blade saves time and frustration because you are not fighting slow cuts and worn-out teeth halfway through the job.

This blade makes the most sense for contractors and serious users already on the Festool track saw platform. It is a smart fit for siding installers, remodelers, general contractors, and anyone cutting fiber-cement panels who wants track-guided accuracy instead of rough freehand work. If your main material is wood framing lumber or finish plywood, this is not the blade to leave on the saw full time. If your main material is fiber-cement board, this is the one you want in the case.

Festool 202958 DIA 160x2,2x20 F4 Abrasive Materials Diamond Saw Blade Is the Right Blade for the Wrong Material

If fiber-cement is on the cut list, this is the blade that keeps your Festool track saw working like it should.

• Who it's for: Pros cutting fiber-cement board, cement-bonded panels, or gypsum-bonded sheet goods with a Festool TS 55 REQ or TSC 55 REB.
• Why it stands out: It is purpose-built for abrasive materials, not wood, so you get better durability, controlled cuts, and cleaner performance in the material this blade was made for.
• Worth knowing: This is a specialty blade. If you mainly cut plywood, framing lumber, or finish stock, keep a wood blade on hand and swap to this one only when the abrasive stuff comes out.

• What material is this blade made to cut? It is designed for fiber-cement and other abrasive materials, including cement-bonded and gypsum-bonded chipboard and fiberboard.
• Which saws does it fit? Festool lists it as suitable for the TS 55 REQ and TSC 55 REB track saws.
• What size is the blade? The blade diameter is 160 mm with a 20 mm arbor hole and a 2.2 mm cutting width.
