We have mentioned a quick and easy way on how to cut different angles with a circular saw blade.

Without wasting any time, let’s dive right into it. 

How to cut a 90 Degree Angle with a Circular Saw 

For a 90 degree angle, the first thing you need to do is inspect the lever at the front of your circular saw. 

You need to ensure the lever is at the 0 marks. Then, place the tip of the base plate on the material you’ve chosen to cut. 


Important Note: Your base plate should level on the wood pointing downwards. 


Start your blade and push the wooden plank against the saw. 

Slice the wooden plank to the end to make a smooth 90-degree cut. 

How to make a 60-degree cut with a Circular Saw Blade 

It is crucial that you check the lever angle to see where the marker points on the base of your plate. 


Note: Your marking should be 30 degrees on the base plate. 


You can loosen your lever to adjust the measurement.

Adjust the base plate on the wood you want to cut. Your blade should be bent inwards. 

Now start the blade and cut across the wood so you can get a clean 60-degree angle. 

How to Cut a 45-Degree Angle with a Circular Saw 

Cutting a 45-degree is not as intimidating as you think. It is quite similar to cutting the previous angles. 

First, you need to set the lever at a 45-degree angle and place the base wood firmly. 

Follow your markings and slice of the wood by cutting with your circular saw.

How to Make Rough Cuts with a Circular Saw – Step-by-Step Guide

Things You Should Know Before You Cut Angles 

Before you get started with your DIY project, there are a few things that you should know. 

Let’s take a quick look at what they are: 

The Angle Lever 

An angle lever sits on the front of the saw attached with a small metal plate. This usually has markings from 0 to 45. You can rotate the dial to loosen or tighten the lever. 

When the lever is at 0 that means that the circular saw blade will cut 90-degrees. Similarly, if you set the lever at 30, you will have an angle of 60-degrees between the blade and the base plate. 

Base Plate Markings 

The base plate has markings from 0 to 45. These notches help you determine the angles and the direction of the circular saw blade. 

If you do not reset the lever and your notch is at 0 that means your circular saw blade is at a 45-degree angle. 

Precautionary Measures

It is crucial that you take precautionary measures before you cut any angle with a circular saw. This could save you from any unforeseen accidents. 

Here are some safety tips you should take in mind:

  1. Always remember to unplug your circular saw before you use it 
  2. Wear safety gloves to protect your fingers 
  3. We recommend goggles because wood shavings could damage your eyes 
  4. You can also use noise-canceling headphones
  5. If you are a beginner, we would suggest that you go through the manual first
