Well, don’t fret, you will be aware of answers to these queries until the end of the article.

However, you might face such a situation due to some technical issues with your miter saw. Mainly, the problem is with the blade of the miter saw. It may be damaged. Moreover, an unstable fence and damaged bevel gauge may also result in crooked cuts.

Through this article, you’ll come to know about various reasons for your miter saw not cutting straight. Therefore, let’s step forward!

Factors Responsible for a Miter Saw Cutting Crooked

The only purpose of a miter saw is to offer users straight, accurate, and quick cuts. If it’s not benefiting you with these things, it’s completely useless for you.

There are several factors responsible for crooked bevel cuts. Let’s discuss some of them below.

1. Damaged Blade of Miter Saw

The blade is sensitive but the most important part of the miter saw. It will not be wrong if we say that all the game of cuts revolves around the blade.

The little shift due to the super-fast, high-power blade may result in a damaged cut. So you need to handle it pretty carefully.

The sharpness of the blade matters a lot in the precision of the bevel cuts. Therefore, keep on checking the blade, whenever you find it dull, sharpen it. This will surely help you to get straight cuts.

Sometimes, there might be some other material getting in touch with the blade while you are cutting your workpiece. This may disturb the straight cutting, so make sure you clean your workplace before using the miter saw.

Furthermore, ensure that the blade of your miter saw has a uniform thickness in order to get straight cuts.

2. Damaged bevel gauge

A damaged bevel gauge is also responsible for faulty cuts. Generally, a bevel gauge is responsible for letting us know the angle of the blade of the miter saw. It is fixed with the fence making a certain angle.

For obtaining the straight cuts, the bevel gauge should be perpendicular to the blade. Therefore, if the bevel gauge is broken, you will get crooked cuts.

However, you’ll not come to know about the breakage until you get inaccurate cuts. Later, you may fix this problem.

3. Unstable Fence

The fence alignment also plays a vital role in maintaining the straight cuts of the miter saw. The main function of a fence is to guide the workpiece in a straight line during cutting.

Therefore, it’s crystal clear that if the fence of your miter saw gets unstable, you’ll obtain crooked and faulty cuts. Only the professional craftsmen who use the miter saw frequently can figure out the unstable fence.

4. Miter Gauge Glitch

The final part of the miter saw you need to check is the miter gauge. Miter gauge mainly holds the workpieces at a certain angle while it’s being cut. However, this part doesn’t come in use for simple cuts, rather it is used while making compound cuts.

While searching for the issue in the miter saw, make sure the gauges are positioned correctly. The shifting of the gauge may result in inappropriate bevel cuts.

Pro Tips for Making your Cuts Straight

The most challenging part is to detect the cause of the problem. Once you have figured out the defect, it becomes easier for you to sort out the issue.

However, for obtaining straight cuts, you must know how to handle the miter saw. If you’re not aware of the correct use of a miter saw, you can never get straight cuts.

Mainly, the factors discussed earlier are responsible for the miter saw cutting crooked. Thus, firstly you need to troubleshoot those factors. If still, you don’t get straight cuts, then you should try the following tips;

• Set a 45-degree angle

The first and foremost step is to set your miter saw at a 45-degree angle. Doing so will line it up with the fence, resulting in straight and accurate cuts.

• Make cuts when the blade reaches full speed.

Never make haste while using a miter saw. You might start cutting the wood as soon as the miter saw gets on, which is a completely wrong way.

At the start, the speed of the blade is slow due to which there are greater chances of getting inaccurate cuts. Hence, wait for a while until the blade catches its full speed.

Cutting the workpiece at the high speed of the blade provides much better cuts.

• Prevent the blade from rushing

As soon as the blade picks up to speed, you start cutting the workpiece but ensure you do not rush the blade. The appropriate way is to allow the blade to make its way through the wood as gently as possible.

Otherwise, it may wear out the blade of your miter saw, so be careful while using it.

• Use a clamp

While making bevel cuts on your miter saw you will observe a slight issue. If you are a newbie then might be wondering what is it.

Let me explain!

Whenever you set your saw for cutting, the blade always pulls the workpiece to itself while cutting. This may disrupt the position of the material in the middle of the cutting process.

Due to this issue, you are always recommended to use a clamp while making the cuts. The clamp holds the workpiece at the set position as long as the cut is made.

Frequently Asked Questions (faqs)

Why is your miter cut off?
