Rated 5.0 out of 5.0 by JamesC Good choice for wood and cellular PVC. Leaves no unsightly swirl marks on the end grains.
After destroying a number of expensive saw blades trying to cut materials they weren’t designed for, you come to know that for every specific cutting job, there is a proper saw blade. A 24-tooth blade is a good choice for ripping or making rough crosscuts in heavy wood, while a 44-tooth blade, such as this one from Diablo, is ideal for giving a semi-smooth crosscut. However, blades designed for use with wood generally do not perform well with Trex or similar composite decking material. Some composites are made entirely of cellular PVC, while others are a combination of PVC and wood (wood-plastic). In either case, they are extremely difficult to cut as most saw blades designed exclusively for wood create too much friction and heat that can melt expensive composite decking material, severely dulling and destroying the blade in the process. This blade from Diablo is designed to dissipate heat, and, although very thin, is rigid so it won't flex and bend under load. I’m in the process of facing a deck with a combination of composite decking and cedar wood. To make my end cuts, I paired this saw blade up with my Milwaukee 7-1/4 circular saw. This blade’s ability to cut both composite and wood materials saves time by not having to change blades. Blades designed for cutting wood can handle short crosscuts of composite material, but will leave unsightly swirl marks on the end grains, but this saw blade from Diablo allows you to make clean end cuts without swirl marks. My only negative comment would be for the price of this blade, which is more than twice that of other blades designed for wood. If the quality of cut and appearance of the end grain on your composite material matters to you or your customer, then this blade from Diablo is worth the every penny, but if you intend to do general cutting and aren’t overly concerned about swirl marks on the end grain, there are less expensive options available. I recommend this blade for cutting composite material. This blade is also an excellent choice for wood cutting.

Rated 5.0 out of 5.0 by jred Smooth, thin, melt-free cuts
When cutting Trex or similar plastic materials, you always have to make sure you cut rather than melt the plastic. In the past I have cut Trex with a fine-tooth circular saw and gotten away with it, but after trying this blade I can say it works better. The cut edges are noticeably smoother, the cut itself is quite narrow (thin kerf means you cut less material), and it cuts easily. I have made a trim cut where the left-over Trex material is paper-thin and flexible, which I consider quite impressive. This blade is rated for up to 10,000 RPM.
Even though this is only a 7 1/4" blade, I have used it on my 10" table saw, and it worked well there.
If you like design details for why the blade may work so well, here are some of the advertised features (see photos): 1) laser-cut stabilizer vents to reduce noise and vibration; 2) thin kerf design removed less material for faster cuts; 3) modified triple chip grind (MTCG) tips for melt-free cuts; 4) Freud TiCo hi-density special blend carbide for ultra-long cutting life; 5) non-stick permashield for less drag and gumming.
So in short, if you are going to be doing much cutting work with composite material, I believe it's worth investing in a blade like this.

Rated 5.0 out of 5.0 by fxp1 Better than most
The Diablo 7-1/4 in. x 44-Tooth Trex/Composite Material Cutting Saw Blade cuts more cleanly using my Craftsman circular saw. It has a thin kerf that reduced tear out and sped up the cut. I haven't used it that long, but the carbide edge means a blade that should last and stay sharp longer. This blade says its for composite materials such as composite decking and PVC, but I've used it on ply and it cuts that just fine. It has a coating to reduce drag and shields against heat, gumming and corrosion. Gumming for me is something I'm always getting which makes cuts harder and creates heat friction. From what I've done with it, its an excellent blade.

Smoothest cutting blade, it has thin kerf. Because of the thin kerf, it provides less waste of materials and it also cuts faster. Therefore it was easier on the skill saw. Does not melt the composite like most other blades, it runs cooler therefore does not run out.. It is a real pleasure to use. Going out to cut more. Will not hesitate to buy more, because it truly is the best blade for cutting composite decking.

Rated 5.0 out of 5.0 by Nonsheep Diablo Blades Rock! Clean & Precise Cuts
Diablo Blades are outstanding! this blade was used for some finish work and had no chips or splintering with it. Zipped right through the material & I didn't smell the familiar smell of burnt or melted material I have experienced with some lesser tool blades. Would do wonders for the Tool Company's would include Diablo Blades with their saws...
I dinged Value because The Blades are Pricey in my opinion. Or maybe I am Cheep!

Rated 5.0 out of 5.0 by Hayviator Smooth cuts and lasts a long time
Just finished a fairly large deck using this blade to cut all composite decking and railings. Blade shows no signs of wear or slowing performance, may be able to get another deck or two built with same blade! Thin kerf reduces material waste and makes a very clean, accurate cut. Was able to use in a cordless saw as it doesn't require a corded saw to power this blade through material.

Rated 5.0 out of 5.0 by Sebastian Clean Cut with Diablo Trex Blade.
This blade is amazingly fast and makes clean cut on a verity of materials.It does not vibrate.
I did test cutting on wood and cement board, several times, and the cuts are very clean. The cut materials never got hot when cutting.
The blade does not eat much since it goes on thin line, so less waste of materials. It is mainly intended for cutting composite materials and plastic, even though we can cut wood too.
I surely recommend it to all.
