The Diablo D0604TSH HardieBlade Fiber Cement Track Saw Blade is a 6-1/2 inch saw blade built for cutting fiber cement products. This is a fiber cement track saw blade designed for repeated cutting in fiber cement material. Model Number: D0604TSH. If you are installing siding, trim, or other fiber cement components and do not want to burn through ordinary blades, this is the kind of dedicated blade you reach for.

What matters here is not just the size, but the job it is meant to do. The blade uses 4 teeth and a polycrystalline diamond tipped cutting edge. That setup is clearly aimed at durability and repeated use in abrasive material. Fiber cement is hard on blades, and this design is built around that reality rather than pretending a framing blade can do the same work.

Diablo also calls this the HardieBlade, and the blade face states it is ideal for large projects and frequent use. That makes it a practical choice for contractors and remodelers who cut fiber cement often enough to care about consistency, downtime, and replacement frequency. It is not trying to be an all-purpose circular saw blade for wood, metal, and everything else. It is a purpose-built cutting accessory for one of the tougher sheet and trim materials on the job.

From a fit standpoint, the blade has a 20 mm arbor and a 165 mm / 6-1/2 inch diameter. Those numbers matter because saw blade compatibility is simple: if the diameter or arbor is wrong, the blade is wrong. This sizing points you toward the saws designed around that format, especially track saw and circular saw setups that accept a 20 mm arbor blade in this diameter.

The blade is rated for a maximum 8,000 RPM, which gives you a clear ceiling for matching it to the saw. That is an important number for safe, proper use and one of the first specs a pro checks before mounting a blade. If your saw is within that range and takes the correct arbor and diameter, you have the basic mechanical fit covered.

This Diablo blade makes the most sense for users who regularly work with fiber cement and want a blade that is honest about its purpose. It is a strong fit for siding crews, remodelers, general contractors, and serious DIY users taking on fiber cement installation. If your work includes repeated fiber cement cutting, the dedicated material design is the whole point of stepping up to this blade.
