Saw Blade Buying Guide for Trex Decking
Building a deck? You’ll need a good saw blade. Trex decking is tough stuff. This guide will help you choose the right saw blade for your project. We’ll look at features, materials, and how to get the best results.
Key Features to Look For
You need a saw blade made for Trex. These blades have special features. Here’s what to look for:
- Tooth Count: A higher tooth count means a smoother cut. For Trex, look for blades with around 40-80 teeth. More teeth give a cleaner finish. Fewer teeth are good for faster cuts.
- Tooth Shape: Choose blades with specific tooth shapes. These are made for cutting composite decking. Think about the type of cut you need.
- Blade Diameter: Make sure the blade fits your saw. The most common sizes are 7 ¼ inch and 10 inch. Check your saw’s manual.
- Blade Material: Carbide-tipped blades are a good choice. They last longer and cut well. Diamond-tipped blades are even tougher, but cost more.
- Anti-Vibration Slots: These help reduce vibration. Less vibration means a straighter cut.
- Kerf: Kerf is how thick the blade is. A thin kerf blade removes less material. It’s easier to push through the Trex.
Important Materials
