You can use the circular saw to make straight cuts, curves, and delicate details. When it comes to making detailed cuts with a circular saw, achieving perfect 45-degree angles is key. Making 45-degree angles with a circular saw can seem tricky, but its quite easy.
In this blog post, Ill show you How To Cut 45 Degree Angles With A Circular Saw? I’ll also give some tips to make these angles as precise as possible. So, whether youre a beginner or an experienced woodworker, read on for all the information you need.
Things You’ll Need
- Circular saw
- Tape
- Sacrificial sheet (MDF, plywood)
- Speed Square
- Straight Edge or Level
- Two clamps
- A Rasp or Sandpaper
Step-by-Step Guide To Cutting At 45 Degrees With A Circular Saw
Step 1:
Tape a straight edge or level to your workpiece. This will ensure that your cuts are precise and straight.
Step 2
Set the depth of your circular saw blade to the desired thickness of the cut.
Step 3:
Place your sacrificial sheet beneath your workpiece. This sheet will protect your workbench from accidental sawdust and debris.
Step 4 :
Align the blade of your circular saw with the angle youd like to cut. This can be done with a speed square.
Step 5:
The saw should be guided along the straight edge of the level or the straight edge, keeping it at an even angle. Keep your hands away from the blade.
Step 6 :
When you reach the end of the cut, turn off your circular saw (and unplug it, if necessary). If youd like, you can make a small mark on the workpiece to indicate where this cut is.
Step 7:
At this point, you might want to clamp another straight edge or level down on the side that you just cut at an angle.
Step 8
Cut another straight edge along the opposite side of the workpiece; depending on your application, this might not be necessary.
Step 9:
Continue cutting until youve completed your desired pattern or design. Congratulations! Youve cut 45-degree angles with your circular saw and it wasnt too difficult at all, was it?

How To Cut 45 Degree Angles With A Circular Saw
- If youre making cuts at multiple angles, make sure to always cut the angles in the same direction (clockwise or counter-clockwise). It’s easier to make multiple precise cuts than to correct one error!
- Instead of cutting down at less than 45 degrees, you can also cut up. This is preferable when you need to make the bottom face of your workpiece flat. To achieve precision, you can use a second straight edge, or level, if needed.
- Make sure that your circular saw blade is extremely sharp before making any cuts. Dull blades will produce less accurate cuts.
- If youre making a lot of 45-degree angle cuts, it might be better to use a jigsaw instead. Although circular saw blades can be very useful in many situations, it is not always possible to modify them. For example, when you are cutting intricate designs with lots of small details.
- Don’t worry if you make a mistake! Don’t worry if you make a mistake. You can always go back and fix them. Just be sure that you wet sand or use a rasp to clean up any rough edges before proceeding!
- Circular saws feature a curved blade and teeth at the inside. If you try to cut with this side of the blade, it will produce a hook or chevron-shaped cut instead of an accurate angle. Be sure to only use the flat, outside part of your circular saw blade for your angle cuts.
- Remember: always work safely and make sure your hands arent in the way of the blade. While a sharp circular saw blade can accomplish amazing things when guided by an expert craftsman, it is also susceptible to serious injury if used improperly. It is important to exercise extreme caution when using a circular saw blade.
Methods To Cut 45-degree Angles Using A Circular Saw
There are several ways to cut 45-degree angles using a circular saw. A miter box, T-bar or straight edge guide are all options.
Using The Miter Box
To cut perfectly 45-degree angles using a circular saw, a miterbox can be used. A miter box of 210 cm is the best size. This will help minimize mistakes when cutting plywood sheets or boards. Most importantly, make sure that the inside corner of your miter is 45-degree. Set the blade on the saw at 45 degrees and connect it with one of its miter slots. Adjust your fence until it matches that angle and locks it in place. Next, place your board inside the box and begin to cut small pieces of wood until it is perfect.
Using T-bar
You can also use a T-bar to cut 45-degree angles with a circular saw. The most important thing is to make sure that the blade is set at the correct angle. Attach the T bar to your saw. Adjust the angle of blade until it matches T-bar angle. You can then start cutting your boards.
Using A Straight Edge Guide
First clamp the straight edge guide to the workpiece if you’re using it. Then, position the saw blade against the straight edge of the guide. Finally, make your cut.
Conclusions
You now know how to use a circular saw to cut 45-degree angles. It’s time to start working on your next project. Be sure to practice on some scrap wood before moving on to more challenging cuts.
Always be safe when working with power tools. We hope you enjoy this handy tutorial. Happy crafting!
