The DART PCD fibre cement saw blade is built for one of the most punishing materials you will encounter on site. Fibre cement board is abrasive enough to chew through standard carbide-tipped blades at a rate that makes them expensive to run, which is exactly why these blades use polycrystalline diamond tipped teeth instead. PCD is considerably harder than tungsten carbide, so the cutting edge holds up far longer when working through the silica-heavy composition of fibre cement products like HardiePlank, Cedral, and similar cladding systems.
Available in five sizes from 160mm up to 250mm, there is a blade here for most cordless and mains circular saws in common trade use. The 160mm and 165mm variants suit the smaller cordless saws that have become the go-to for cladding installs, while the 216mm and 250mm blades cover the larger worm-drive and track saw setups where volume cutting is the priority. Worth checking your arbor before ordering — the smaller blades run a 20mm bore and the larger two use a 30mm bore.
Where DART PCD Fibre Cement Blades Get Used
These blades are the right choice for any trade where fibre cement is a regular material. Cladding installers, dry-lining contractors, and general builders fitting external boarding will all get proper mileage from a PCD blade versus burning through cheaper options every few sheets. The tooth count is deliberately low — 4T on the smaller sizes, 8T on the larger — because fibre cement does not need fine finishing teeth. A lower tooth count clears the cut faster, runs cooler, and extends blade life.
Laminated Board Cutting
These blades also perform well on laminated sheet materials. The PCD tips handle the hard, abrasive surface layers that tend to blunt standard blades prematurely, making them a practical dual-purpose option if you are regularly switching between fibre cement and laminate work on the same job.
One of the practical benefits of a good DART PCD fibre cement saw blade is reduced airborne dust compared to using the wrong blade at excessive speed. Fibre cement dust is not something to be casual about — silica content means proper RPM and dust management still matter regardless of blade quality, but a sharp PCD tooth shears rather than grinds, which keeps dust generation lower from the outset.
Pro Tip: Always check the maximum RPM rating of the blade against your saw's no-load speed before cutting — fibre cement is dense and the temptation to push feed rate is real, but keeping the blade speed within spec and letting the PCD teeth do the work will add significantly more cuts to its life.
These blades are used wherever fibre cement cladding board is being cut to size on site. That covers external wall cladding installations, soffit and fascia work using fibre cement profiles, and sheet goods on new-build and renovation projects. Dry-lining contractors, cladding specialists, and general builders all reach for a PCD blade when fibre cement is on the cutting list.
They also suit laminated board cutting, making them a practical choice on jobs where you are working across a mix of abrasive sheet materials in the same session.

Extended blade life on abrasive materials
Not suitable for: Not suitable for cutting timber, steel, or general masonry. These blades are optimised for fibre cement and laminated boards — using them on standard softwood or hardwood is unnecessary and will not give better results than a conventional wood-cutting blade.
Fit the blade ensuring the bore matches your saw's arbor spindle and the blade is seated flush against the flange. Double-check rotation direction marked on the blade matches your saw. Set cutting depth to just clear the board thickness — no deeper than necessary.
Use a steady, controlled feed rate. Fibre cement is dense and will resist being rushed. Forcing the cut generates heat, increases dust, and shortens blade life faster than anything else. Where possible, use a guide rail or fence to keep cuts straight and reduce the chance of binding.
Wear appropriate RPE rated for silica dust. Fibre cement contains crystalline silica and cutting it without dust control or respiratory protection is not worth the risk, sharp blade or not.
Confirm the blade bore matches your saw's arbor — 20mm for smaller saws, 30mm for larger models
Fit the blade with the rotation arrow matching the direction of your saw's spindle
Set cutting depth to just beyond the board thickness, avoid excessive depth
Secure the fibre cement board on a stable surface with adequate support either side of the cut line
Use a guide rail or fence for straight, repeatable cuts
Feed at a steady, controlled pace — let the PCD teeth do the work rather than forcing the saw through
Wear silica-rated RPE and work in a ventilated area or use on-tool dust extraction where available
After use, inspect the blade for any chipped or damaged teeth before storing
Can I use this blade on a cordless circular saw?
Yes. The 160mm and 165mm blades in particular are well suited to cordless circular saws, which are commonly used for fibre cement cladding work. Just confirm your saw's arbor bore is 20mm and check the blade's maximum RPM against your saw's no-load speed before use.
How much longer do PCD blades last compared to standard carbide blades on fibre cement?
Significantly longer. Fibre cement is highly abrasive due to its silica content and it dulls standard carbide teeth quickly — sometimes within a single sheet on cheaper blades. PCD tips are considerably harder and will typically last many times longer in the same material, making the higher upfront cost straightforward to justify on any job with a reasonable volume of cuts.
The cutting teeth on these blades are tipped with polycrystalline diamond, a synthetic material formed under high pressure that sits at the top end of the hardness scale for cutting tool materials. This makes PCD the appropriate choice for fibre cement, which contains Portland cement, silica sand, and cellulose fibres — a combination that is extremely abrasive to conventional tungsten carbide. The low tooth count (4T or 8T depending on diameter) is deliberate, allowing efficient chip clearance and reduced heat build-up during sustained cutting.
