FAQs
Do you need a special blade to cut Trex decking?
Yes, you do. Trex is made from a mix of wood fibers and plastic, which makes it denser than natural wood. A standard wood-cutting blade may tear or splinter the surface. For best results, use a carbide-tipped blade specifically designed for composite or non-ferrous materials. These blades stay sharper longer and deliver smooth, burn-free cuts.
What saw do you use to cut Trex?
The type of saw depends on your project. A circular saw works well for straight cuts, while a miter saw is perfect for angled cuts on deck borders. For notching or intricate shapes, a jigsaw with a fine-tooth blade is more effective. The key is using a saw with enough power and pairing it with the correct blade designed for composites.
What blade is used to cut composite deck boards?
For composite decking like Trex, a carbide-tipped blade with 40 to 60 teeth is the standard choice. A thin kerf design reduces resistance and ensures cleaner cuts. Blades with alternate top bevel (ATB) or triple chip grind (TCG) tooth patterns perform especially well, as they minimize chipping and extend blade life when cutting dense materials.
How many tooth saw blade for composite decking?
The ideal tooth count is between 40 and 60 teeth for circular saws, depending on the blade size. A 7-1/4 inch blade with 40 teeth provides a balance of speed and cut quality. If you want an ultra-smooth finish on visible edges, a 60-tooth blade will give better results, though it may cut more slowly. The goal is to balance efficiency with precision.
Conclusion
Choosing the best saw blade for cutting Trex decking comes down to using a carbide-tipped blade with the right tooth count and saw type. A 40-tooth blade works well for most projects, while a higher-tooth blade ensures finer edges. Pair it with a reliable circular or miter saw, and you’ll get clean, professional results without damaging your composite boards. With the right setup, your deck project becomes smoother, faster, and far more precise.
