1. Blade Size

First off, you should select the right blade size. Common miter saw sizes include (but are not limited to) 8, 10, 12, and 15 inches. Larger blades can create deeper and longer cuts. However, we’ve found that a 10 or 12-inch miter saw blade is sufficient for most jobs.

While you can use a larger sized miter saw for cutting small boards, it will be harder for you to achieve accurate cuts. So, you must buy a miter saw with a blade size that is just right for the job.

2. Motor Power

The power of a compound miter saw motor is measured in amps. Miter saws with high powered motors have more cutting power and can make deeper cuts.

Therefore, if you want to make a lot of crosscuts for a carpentry job, go for a high powered miter saw. Similarly, a saw with a high power rating is ideal for installing shutters or gates, building a garden shed, or building a tree house.

3. Positive Stops

Compound miter saws have positive stops for commonly used angles. These are factory set points that let you quickly choose the right angle for cutting boards. Some miter saws have thumb-activated stops. The feature allows quick adjustments, saving you a lot of time when making a cut.

Miter saws also come with depth stops, which allow you to easily adjust the blade height. You can control the depths of the cuts. Saws with stops are relatively pricier, but they will save you time and offer convenience while cutting.

4. Electric Brakes

Electric brakes are also a useful feature that reverses the electricity flow when you release the trigger. The blade can stop in as little three seconds. This feature is important if you are into carpentry as it can save you a lot of time. 

5. Articulated Blade Guards

If you’re wondering what to look for in a compound miter saw, a miter saw with articulated blade guards is the answer. When the saw is raised, articulated guards cover the blade completely.  It offers carpenters a better view of the cutting line.

Additionally, the guards also protect the blade when the saw is in use. The guards can automatically adjust, depending on the thickness of the material.

6. Miter Detent Override

Miter detent override is another important feature you should look for in a compound miter saw. The feature allows detent action to be locked out when cutting a board. As a result, you can make micro-adjustments to the angle and get the desired cut.

With a compound miter saw having a miter detent override feature, you can position the saw close to the miter stops. This makes it easier for you to operate the saw at an angle.

7. Spindle Locks

A miter saw with spindle locks is another important feature you should look for in a compound miter saw. It allows you to immobilize the blade or shaft. In this way, you can quickly change the blade when required.

8. Guide Lights

Guide lights are another useful feature to look for in a compound miter saw. The lights project a beam onto the workpiece and help in getting accurate cuts. Compound miter saws come with standard guide lights or laser guides.

9. Sliding Compound Miter Saw

Sliding compound miter saws offer more flexibility during a carpentry job. But it is more expensive as compared to a standard miter saw. The saw has the same features as a traditional compound miter saw with the exception of a sliding arm.

The sliding arm of a sliding compound miter saw ensures wider and thicker cuts. You can cut thick materials like wood with it. It is also the right option for cutting larger materials.

10. Power Source

When buying a compound miter saw, check its power source. Most miter saws are corded and have motor ratings of up to 15-amp power. If you work on small carpentry projects, you can select a portable cordless miter saw.

Cordless miter saws are battery-powered and are suitable for simple DIY carpentry jobs. The saws are generally smaller and lighter as compared to corded saws. These are best for small to medium needs. The saws often have brushless motors that require little maintenance and are also durable.
