Cutting a 135-degree angle on your miter saw is an essential skill for any woodworker. Even if you are not into DIY and crafts, there are many uses for this type of cut in the home workshop. In this blog post, we will show you how to use a miter saw to make the perfect 135-degree angle cuts with ease.
There are a lot of benefits that come with this technique, and it’s worth taking the time to learn how to do so. You’ll also find some safety precautions for those who have just bought their first miter saw or don’t have much experience using them yet.
Finally, there is two simple formula for cutting the 135-degrees angle. The end result should be a cleaner cut and less wasted material when trying out different techniques such as crown molding or building cabinets that require tight corners.
What is a Miter Saw?
A miter saw, also known as a chop saw or tenon saw, has an adjustable blade that can cut the wood at different angles. It’s used to make precise cuts for molding and joinery work.
In a miter saw, there is no sign for a 135-degree angle cut. So how do you cut it?
Obviously, there is a solution. So, let’s see this.
Formula to Cut 135-Degrees on a Miter Saw
For making 135 degrees angle, we need to cut a 22.5-degree angle first. For cutting an obtuse angle, we can use two different formulas. By using the obtuse angle from the formula, we can get the desired 135 degrees wood angle by making an inside cut and joining the two pieces of cutting wood.
Suppose X is the desired angle (135 degrees), and Z is the angle that we will get from the below two formulas:
Formula-1:
180-X = Y Z = Y/2
Let us apply Formula-1 and prove it.
180-135 = 45 and 45/2 = 22.5 which is the angle for the miter saw.
Formula-2:
X/2 = Y Z = 90-Y
Let us apply Formula-2 and prove it.
135/2 = 67.5 90-67.5 = 22.5 which is the angle for the miter saw.
So, the two examples prove both formulas work, and we can get the 22.5 degree that requires for 135 degrees angle cut.
Now let us go through the detailed process for cutting 135 degrees angle.
How to Cut 135-Degrees Angle on a Miter Saw
The first step in cutting your angle is setting up the tool properly. Position your miter saw so it will be exactly 22.50 degrees from one pointy edge of the board you are trying to cut (which we refer to as “the object”). You should see two points protruding out behind the back wheels of your miter saw which represent 0 degrees and 180 degrees laterally – these are called the “blade guard.”
Once you have your miter saw set up, use the bevel gauge on the front of it to find a 22.50-degree angle. Place one side’s edge against this pointy edge and then draw an arc with your pencil that extends out over the blade – do not let go of either end!
Now put the other side of your bevel gauge to that same peak (a different point) and see if they are at a 90-degree angle relative to each other. If so, you’ve got yourself a 22.50-degree miter saw cut in perspective for more or less any kind of project you need it for!
Step by Step Guides:
Follow these steps until perfecting cutting angles becomes second nature:
- Measure the angle you need using a protractor or bevel gauge
- Set up the miter saw and line it to where the cut will happen, then make sure that is set correctly
- Mark your measurement on one side of what you’re going to cut (so if doing a 22.50 degree cut like we just did, mark at even 23 inches)
- Line up with edge so it’s not longer than 45 degrees off from perpendicular – this ensures accurate cuts! This can also help prevent “kickback,” which happens when the wood moves back toward you once being hit by the blade. “Matching” angles is important because all these measurements are based around 90 degrees; for example, if someone needs another ten degrees off of a 90-degree angle, it would be from the other side so that they match up
- When you’re sure everything is lined up right and ready to go – start with your saw’s blade touching what needs to cut
- Move quickly through the wood while holding at a stable position; once done, move away as soon as possible. Let the blade stop spinning before doing anything else!
Safety Precautions
The most important thing about using any power tool is safety. If you can’t do something safely then DON’T DO IT AT ALL!
As long as you keep these precautions in mind when operating this powerful machine then there shouldn’t be too many problems:
- Always wear protective eyewear like goggles or glasses if cutting wood, or a mask if cutting metal.
- Stand clear of the path to prevent bodily injury from flying debris.
- Never cut near power lines or any other electric cables – if you’re unsure whether it’s safe, then don’t do it.
- Place wood scrapers nearby so that all your excess material can be safely collected rather than left on the floor and potentially cause slipping hazards for co-workers or others entering the workspace.
Miter Saw Safety Tips
Using the miter saw safely everyone’s demand. But newbies don’t know even not aware of that. But it plays an important role. Let’s get some miter safety tips for all woodworker’s safety.
Stay Clear Of The Blade:
It can be easy to forget about blades because they’re not moving most of the time! But it only takes an instant for someone’s fingers/hands to come into close proximity with one so don’t forget to stay clear of the blade.
Use Proper Height:
A miter saw’s height is typically adjusted by using a lever that can be found on one side, and it controls how high from the ground the saw will cut at for various angles. Make sure you adjust this according to your needs every time before use so as not to accidentally injure yourself or damage any surfaces in case something falls unexpectedly.
Maintain Miter Saw Blade Sharpness
Keeping blades sharp is crucial because they’re what actually does all of the cutting work! To maintain their edge, start with running them along with a file that has been set at an angle (usually around 24 degrees) while moving away from oneself then follow up with honing them against sandpaper attached perpendicular to a surface.
Additional Information
You will want to become familiar with this machine before attempting anything too complex, but once you learn what each button does along with how to use the blade rotation and speed settings – there really is no limit as to what tasks are possible.
There has been some debate about which direction an angle should be set to cut on a miter saw. Some say that the 22.25-degree angle is the best because it provides cleaner, more accurate cuts, and wastes less material when cutting at an angle; while others argue in favor of using 45 degrees as this has been found to be safer for certain types of materials such as metal or plastics.
Final Words
Cutting a 135-degree angle on your miter saw is not an easy task, but this article will share some tips to help you do it. There are three angles that you can cut with the blade of your saw: 22.5 degrees, 45 degrees, and 90 degrees; which when combined allow for cutting at a 135-degree angle as well. You should use these other types of cuts in order to make clean edges while also saving up money by buying cheapo blades!
These tips should give anyone looking into how to effectively measure their workspace or project area more insight, so they don’t have any problems doing what needs to be done before getting started.
