How Deep Will A Circular Saw Cut?


The portability and versatility of circular saws make them a popular tool. However, the skillful use of them requires practice. If you are familiar with circular saws, you might be wondering what the depth of a circular saw cut is. 

So, how deep will a circular saw cut? Your blade length and circular saw size could affect the depth of your cut. Generally, a circular saw can cut up to two and a half inches deep, but it is customizable and dependent on the size of the blade you use.

You can easily transport this lightweight, compact tool to work sites. Circular saws cut material by rotating the blade. It is a good choice for cutting plywood, hardwood, and sheets since it achieves smooth, neat, and accurate results. A blade designed for rough materials, however, would be beneficial.

Following the steps outlined below is an effective way of learning how deep a circular saw can cut.

Step 1: Get to know the blades

Multiple cutting depths are possible with blades and saws of various sizes. However, woodworkers consistently use special sizes the majority of the time and rarely use circular saws with blade sizes larger than 10-1/4 inches and 16-5/16 inches.

Ensure that you never use dull blades on your circular saw. It would be best if you always had razor-sharp edges. Sharp edges make the process easier, safer, and more effective. Taking precautions when assembling circular saw blades is essential. Remove the blade from the circular saw before changing it. In addition to spinning very quickly, the edge can cause severe injuries if mishandled.

Step 2: Determine how deep to cut

The maximum cutting depth of a circular saw is two and a half inches, which can be customized. As a rule of thumb, your record cut should be between 4-1/4 and 7-5/16 inches deep. You can effortlessly handle big wood and metal pieces with a circular saw. 

However, with circular saws, the cutting depth should be less than the blade radius due to the blade pivoting in the middle. In this way, the depth of the cuts made with a circular saw can be more precisely determined. 

Before moving forward:

  1. Be sure that your circular saw is working correctly.
  2. Confirm the retractable guard retracts and retracts properly.
  3. Avoid using circular saws with faulty lower guards.

Step 3: Adjust the depth

Start by removing the lock on the circular saw’s back to loosen its baseplate. After you place the base plate on the material, adjust the depth of the blade by adjusting the height of the saw. It would be best to replace the shoe level when aligning the blade. When cutting wood with a circular saw, you must know what depth of cut to use. 

While setting the depth of cut, ensure that the blade does not stick out a lot below the surface. It will provide an accurate and safe cut. 

Cut depth 

You can cut as deep as the mounted blade of the cutting saw allows, depending on its size. You will have a depth of two inches and 12 inches with blades of seven inches and 14-1/6 inches. As an amateur, the size of the blade mentioned should be ideal. 

Professionals use blades that are ten inches or 14 inches, while specialists use 16-inch or 5/16-inch blades. If you are going to do a lot of DIY work, you should consider 13/16-inch blades. Professional woodworkers cut large pieces of wood, metal, and timber, so they need a larger blade size.

Adjusting the blade depth

Depending on your needs, you can adjust a circular saw from maximum to minimum depth. First, pull down on the rear of the saw to release the lock and remove the baseplate. Then, place the baseplate on the material, and move the cutting edge up and down to change the saw’s height. Set the shoe level back at the cutting edge once you are finished with the adjustment process.

However, you should not adjust the blade too deeply. Otherwise, it may cut the material rough. There are also some specifications you need to know. You can achieve a two-inch depth by adjusting the blade by 2-1/4 inches. Always calculate the depth of a cut before cutting it so that the cut will be clean and smooth. 

Standard circular saws have maximum cutting depths, which you can adjust to meet our needs. To do this, place the baseplate on the material and adjust the saw’s depth or height. Remember to put the shoe level back in place once you are finished aligning the blade.

Circular saws are well known for their versatility and ease of use. However, understanding the depth of your circular saw cuts can be challenging. Here are the depths to which circular saws can cut depending on the length of the blades. 

  • Circular Saw of 10 Inches

You can get a cutting depth of 3-13/16 inches with a ten-inch circular saw. A circular saw with this depth should be sufficient for thick wood. To cut this deep, you will need a good electrical connection. 

  • Circular Saw of 8-1/4 Inches

Using an 8-1/4 inch circular saw can cut to a depth of approximately 2-7/8 inches.

  • Circular Saw of 7-1/4 Inches

A standard 7-1/4 inch blade can cut up to two and a half inches deep. It should be a good depth for a circular saw used at home. 

  • Circular Saw of 6-1/2 Inches

A 6-1/2 inch circular saw blade can cut approximately two and a half inches deep.

  • Circular Saw of 5-1/2 Inches

Using a blade of 5-1/2 inches, you can cut a depth of 1-13/10 inches.

Applications of a 6-1/2 circular saw

DIY projects can be a lot easier with a portable circular saw. Usually, a manual saw is sufficient for DIY projects that involve stocks, wood pieces, or smaller pieces of material. The small blade ensures that your hands will not become tired even if you work for a long time. Because of its larger blades, it is more portable and lighter than circular saws with small blades.

If you are dealing with thin pieces of material for a long time, it may be easier to use a circular saw. With a circular saw blade of 6-1/2 inches, you can easily cut wood pieces or other material with a diameter of two inches. The blade will not cut through more than two and a half inches. Moreover, most tools allow you to change the angle accordingly as needed.

It is excellent for cutting small pieces of wood or roof sheets. If you are not going deeper than two and a half inches, you will need a circular saw with a blade of 6-1/2 inches. Circular saws are more convenient and portable for lighter-duty tasks than saws with 7-1/2 inch blades.

The blade on the left

You can get a depth of up to 1/364 inches using the left blade at a 90-degree angle. You can also use a 45-degree blade for cutting 1-3/16 inch pieces. 

Frequently Asked Questions (FAQs)
