Cutting Hardie Board: A Complete Guide
Hardie Board is a popular choice for exterior siding and trim, thanks to its durability and low-maintenance requirements. But cutting this tough fiber cement material can be a challenge. That's where jig saw blades come in. In this article, we'll explore the best jig saw blades for cutting hardie board, as well as some tips and tricks for getting the job done right.
What Is Hardie Board?
Hardie Board is a brand of fiber cement siding that is made by mixing cement, sand, and cellulose fibers. This creates a material that is resistant to fire, moisture, insects, and rot. Hardie Board comes in a variety of styles and textures, including lap siding, vertical siding, and shingle siding.
Why Use Jig Saw Blades?
When it comes to cutting Hardie Board, traditional saw blades just won't cut it (no pun intended). The material is too tough for most standard blades, and may even cause damage to your saw. Jig saw blades, on the other hand, are specifically designed for cutting fiber cement materials like Hardie Board. They have a unique tooth shape and edge geometry that allows them to slice through the material cleanly, without chipping or cracking.
The Best Jig Saw Blades for Cutting Hardie Board
So, what are the best jig saw blades for cutting Hardie Board? There are a few different options, depending on the exact type of Hardie Board you're working with and the depth of the cuts you need to make.
- Bi-Metal Blades: These blades are made from two different types of metal, usually high-speed steel and cobalt, which makes them strong and durable. They are a good choice for general-purpose cutting of Hardie Board.
- Carbide Blades: Carbide blades have a diamond-shaped carbide tip that makes them incredibly tough and wear-resistant. They are the best choice for cutting thicker Hardie Board, or for making intricate cuts.
- Diamond Blades: Diamond blades are the most durable and long-lasting option for cutting Hardie Board. They are coated in industrial diamonds, which makes them incredibly strong and able to handle even the toughest materials.
Tips and Tricks for Cutting Hardie Board
Now that you know which jig saw blades to use, here are some tips for cutting Hardie Board effectively and safely:
- Wear protective gear, including gloves, goggles, and a dust mask, as cutting Hardie Board can produce a lot of dust and tiny, sharp particles.
- Use a saw with a dust collection system, or hook up a vacuum to your jig saw to reduce dust and debris.
- Make sure your saw blade is sharp and in good condition before starting to cut.
- Set the blade depth so that it just barely cuts through the material, rather than trying to force it through all at once. This will prevent chipping and cracking.
- Use a straight edge or guide to keep your cuts straight and accurate.
- If you need to make a curved cut, use a jigsaw with variable speed control to maintain a consistent speed.
Conclusion
Cutting Hardie Board doesn't have to be a daunting task. With the right jig saw blades and a few tips and tricks, you can get clean, accurate cuts without damaging your saw or the material. Whether you're a DIY homeowner or a professional contractor, having the right tools and knowledge can make all the difference.
