Expert Advice: How to Cut a 90-Degree Angle with a Hand Saw

The challenge increases considerably if you’re trying to cut a straight line on an angle with a hand saw. Very soon, you’ll recognize your geometry class knowledge about angles when you start dabbling in woodworking.

It wouldn’t be possible to perform some of your mission without cutting angled pieces. However, the accuracy of your angles will affect the outcome of your projects. Here is a quick guide on how to cut a 90-degree angle with a hand saw of your sketch perfectly.


What Is a 90-Degree Angle?

What is degree; I mean, what is a 90-degree angle? Well, 360 degrees marks a full circle of rotation and a 90 degree known as a right angle.

Why Is It Important?

In reality, you will rather hear “90-degree angle” or “right angle” when it comes to practical utilizations. You will find right angles everywhere in all parts of life, including construction, organization, art, driving, and more.

Note: Of course, it’ll be the super easiest way to make angled cuts using the miter saw. Now, you can also cut 90-degree angels using the ordinary handsaw without wasting your stiff earned money. Making 45-degree to 90-degree angled cuts can be pretty straightforward if you know how to act it.

Technique To Make 90-Degree Angle Cuts Using Your Handsaw


Of course, cutting angles using a handsaw is trickier, but if you don’t have a miter saw or want to ignore it; so move forward with your own handsaw. Hence, you need to know how to come up with excellent angled cuts using a handsaw:

Trying Out a Miter Box

Truly, cutting a 90-degree angle is not simple if you are a beginner. However, with the use of a miter box, cutting can be done more accurately and precisely. This box is equipped with angled slots on its sides that act as guides so the saw won’t tilt when cut vertically.  It is possible to make 45°, and 90° cuts without stress about the handsaw sloping.

Cut Using a Tenon Saw:

  • If you’re using a miter box, you can apply a tenon saw to cut a 90-degree angle. Although the tenon saw is a bit shorter than the standard handsaw, it’s comfortable to use.
  • In addition, it comes with smaller teeth that reduce the risk of tear-out at the wood fiber’s end.
  • Additionally, the blade’s rigid spine prevents it from warping or bending too much during cutting. By virtue of this characteristic, tenon saws can cut 90- degree angles more easily and yields better results.

Careful, cut on the waste side:

  • Accurate cutting is dependent on the kerf of your saw importantly. Sometimes it can create gaps, especially if you’re doing joint or fine works.
  • Of course, the kerf is the width of the saw; therefore, you should always trim on the waste part of your pencil line instead of cutting exactly in the center.

Cut Without A Guide By Evaluation Or By Eyeing The Angle

  • The method of creating 90-degree angled cuts may be sufficient for projects that don’t require the utmost exact result. However, cutting by eye is variable unless you’re an expert in using handsaw on woodworking or any job.
  • Want to cut without a guide (miter box)? Make a thin line by using a sharpened pencil on your items.
  • You can purchase an excellent 90-degree cut wood from a store, but you’ve to confirm its edge is a perfect right angle.
  • Check out the top side is absolutely angled; you can apply a carpenter square.
  • Once you have marked the two vertical sides of the wood, you can grip the piece and cut using a handsaw and can likewise use a vise to hold the objects securely.
  • Pay attention and ensure that, for error-free 90-degree angles, maintain the blade straight while you trim.
  • The pencil tip should be placed on the mark you made at the outset. Next, slide the tool (square) against the direction, and mark the tip along the engineering square.

You Can Use An Angle Finder

  • You may use a digital angle finder if you want to cut different angles besides 90 degrees.
  • Between the two sides of wood can be calculated with a digital angle finder. Alternatively, you can use it as a slant gauge to transfer the angle to wood. Identify the rafter’s end prior to cutting.
  • Draw lines down both sides of the timber using the angle finder after marking the top of it. After dropping the lines, you can join their ends on the underside.
  • Now, remove the angle finder, take your handsaw and get ready for cutting.
  • Place the wood according to how easy it is for you, and then gently and precisely cut along the marked line.
  • After the cut, you can clean it up to ensure the right angle is achieved.

Note: When cutting along a mark, consistency is essential. Nevertheless, don’t be too tough on yourself, as projects with angled cuts are not entirely square. Furthermore, moldings, for example, bend and warp, and saws aren’t 100% straight and faultless.

Final Word

Devoid of using a miter saw; indeed, you can still manage to cut 90-degree on your desired segment. Still, questions, how to cut a 90-degree angle with a hand saw? Anyway, if you’ve sufficient funds, don’t hesitate to pay out for a miter saw because it will surely deliver a 90-degree angle cut as well. However, you can follow up on the tips mentioned above on cutting angles with your hand saw fittingly.
