Most miter saws for crown molding comes with general-purpose blades. For that, you might not get the desired results in your crown molding installation projects since the quality of your miter cuts solely depends on the type of miter saw blade you’re using. Moreover, regular miter saw blades become dull quite fast as they can’t withstand wear and tear, especially when used for tough applications.
Luckily, you can avoid these challenges by upgrading to the best miter saw blade for trim and crown molding. This will allow you to enjoy the smoothest miter cuts, compound angle cuts, and cross-cutting for your trim work, cabinet making, furniture building, and crown molding installation projects.
However, with so many types and sizes of miter saw blades in the market, how do you find the perfect one for your crown molding and trim work? Well, you just did! In this guide, I’ve reviewed the top 3 miter saw blades that are suitable for trim and crown molding projects.
But first, let’s look at the benefits of choosing the right type of miter saw blade for crown molding and some of the important factors you should consider!
Why should you choose the right type of miter saw blade for trim and crown molding?
In addition to improving the outcome of your work, choosing the right type and size of miter saw blade offers several benefits. For instance, a good quality miter saw blade makes an effective cut on your crown molding pieces or any material you’re working on. This will help you make cleaner and smoother cuts within a short duration.
At the same time, a miter saw blade that can smoothly slide or run on the material of your crown molding and trim will protect the motor of your miter saw from early damage. That’s because the motor tends to wear out quickly if it’s generating too much heat energy to forcibly run the blade through the material you’re cutting.
Lastly, a good working miter saw blade ensures safety throughout the operation of your tool.
Factors to consider when buying the best miter saw blade for trim and crown molding
There are various factors that miter saw experts when choosing a miter saw blade for trim and molding. Understanding these factors will help you narrow down the best miter saw blade for your projects. Some of the most important features include;
Miter saw blade size
Generally, the miter saw blade size refers to the diameter of the blade. There are various sizes of miter saw blades ranging from 5 to 15”. 8”, 10”, and 12” are the most popular sizes, although smaller trim saws usually use 7.25” or 8.5” blades. For that, it’s important to ensure that you have selected the right blade size for your crown molding miter saw since there is no one size fits all.
Luckily, miter saws are usually marketed with the size of the blade. For instance, a 10” miter saw requires a blade with a diameter of 10”.
The most commonly used blade sizes for crown molding are 10” and 12” blades. In most cases, a 10” miter saw blade will get the job done. However, if you intend to cut thicker materials, you might need a 12” blade since the blade only cuts objects half its diameter. Therefore, a 10” blade has a maximum cutting depth of 5”. So, if you want to make cuts that are deeper than 5”, you’ll need a 12” blade.
Number of teeth
You will also note that miter saw blades have different numbers of teeth, ranging from about 14 to 120 teeth. The number of teeth on a blade determines the type of cut and material you should use it on. For instance, the more teeth the miter saw blade has, the finer and smoother the cut will be.
In this case, since you’re looking for a miter saw blade that will help you make clean cuts in trim and molding, choose a blade with about 80 teeth. This will help you make cleaner, smaller, and more precise cuts at a slower speed, thus reducing the chance of burning your crown molding material.
It’s also worth mentioning that a larger blade requires more teeth compared to a blade with a smaller diameter. So, if you want to do cross cuts with a miter saw, choose a tool with at least 70 teeth for the 10” blade and 80 teeth for the 12” blade. However, if you want to get smooth cuts, you can choose blades with more teeth.
Miter saw blades are usually made from steel, which allows them to cut through various materials such as stone, metal, ceramic, and wood. Unfortunately, steel blades tend to become dull after limited use. For that reason, their teeth/ tips are crafted with other materials that last longer.
Two of the most commonly used materials for miter saw blade tips/ teeth are carbides and High-speed steel (HSS). Carbide is the most preferred material since it stays sharp for a much longer time than high-speed steel. The only issue with carbide-tipped miter saw blades is that they can be a bit pricey. So, if you’re looking for an affordable miter saw blade, look for an HSS miter saw blade.
Apart from carbide and high-speed steel, some blades are diamond tipped, allowing them to handle both wood and masonry work. However, such blades are commonly used in professional settings as they’re even more costly than carbide-tipped blades.
Arbor/ Bore size
Arbor size refers to the diameter of the hole in the center of a miter saw blade. Before you settle on a particular blade, it’s important to ensure that its arbor size is compatible with the crown molding miter saw. Most 10” miter saws have a ⅝” arbor, while 12” miter saws have a 1” arbor. However, make sure you check your miter saw’s arbor size before you buy any blade.
If the bore/ arbor size is too small, the blade will wobble and vibrate during use, which can damage your saw and cause kickback. Contrarily, if the bore size is too large, the blade will not fit properly on your miter saw.
In a miter saw blade, Kerf refers to the width of the cut that the tool will make, usually measured in millimeters. For most molding and trim applications, avoid using a blade with a large kerf width. Instead, the best miter saw blade for trim and molding should have a kerf width of around 2 mm. A thinner miter saw blade reduces chipping and allows for a more precise cut.
3 Best Miter Saw Blades for Trim and Crown molding
First on the list is the Makita A-93681, which is a great option for anyone looking for an affordable miter saw blade for trim and crown molding. The blade is crafted from high-quality carbide steel.
