CUTTING STRAIGHT IS HARDER THAN IT LOOKS, HERE'S A FEW TIPS
Cutting a board straight with a circular saw is an essential skill for every tradesperson and DIY enthusiast. A straight cut ensures a professional finish and guarantees the structural integrity of a project. However, achieving a perfectly straight cut with a circular saw can be challenging if you don't use the right tools and techniques. In this blog post, we'll discuss how to make accurate, straight cuts with your circular saw every time.
SAFE CUTS ARE STRAIGHT CUTS
Before cutting, ensure your work area is clean and free from loose items that could cause accidents. It’s essential to have good lighting and a dust extractor so you can clearly see the cut line. Always wear safety glasses and hearing protection. Injury or a ruined cut line could result if you can't see, if your power cord gets in the way, or if you trip on a tool.
NEVER CUT FREEHAND
Though some seasoned professionals may feel comfortable cutting freehand, and it may seem fast and convenient, it's not the safest or most accurate method. Freehand cutting can lead to jagged edges, kickbacks, and may increase the risk of injury. Always use a guide or a fence to ensure a straight cut when using a circular saw.

INVEST IN A QUALITY GUIDE RAIL
Investing in a Festool guide rail will significantly improve the accuracy and quality of your cuts. A good guide rail offers a solid, straight edge to guide your saw, reducing the chance of the saw veering off course, and ensuring a perfectly straight cut every time. Remember to secure the guide rail to the workpiece using a clamp, and use a guide rail that spans the entire length of the desired cut.
You can choose a standard guide rail, a crosscut guide rail, or alternatively, a side fence which attaches to the saw to sit on the edge of the workpiece and guide the blade. Guide rails come in various lengths, and the saw glides smoothly and securely along the channel in the guide rail. Guide rails are the most efficient, safe, and accurate way to achieve straight cuts with a circular saw.
TAKE CARE OF YOUR TOOLS
The best tools are the ones that are in perfect working order. Taking care of your guide rails ensures they don’t accidentally bend. Keeping your blade sharp and clean, and replacing damaged and warped blades is critical to creating clean, straight cuts. Dull blades and warped guide rails will increase the chance of kickback and uneven cuts.
KEEP YOUR PIECE SECURE
Before you begin cutting, make sure your entire workpiece is supported and securely clamped to prevent it from shifting while you cut. If the piece moves while you are cutting, it can result in a crooked cut or, worse, an injury. Use sturdy clamps and a solid workbench to keep everything in place.
TECHNIQUES TO CUT A BOARD STRAIGHT
Start the saw before it contacts the wood, allowing the blade to reach full speed before beginning your cut. Apply steady pressure, but avoid forcing the saw through the material to prevent kickback. Let the saw do the work. Keep your body positioned to the side of the tool rather than directly behind it to protect yourself in the event of a kickback. Make sure your feet are planted securely, and you are always in control of the saw. Lastly, when using a corded saw, ensure the electric cable has plenty of slack so it doesn’t get caught on anything.
Cutting a board straight with a circular saw requires attention to safety, proper tool care, and the correct cutting techniques. By following these steps, you'll achieve straight and clean cuts every time.
