Bosch GCM12SD 12-Inch Corded Dual-Bevel Sliding Miter Saw

A superb dual-bevel sliding miter saw from Bosch with a 12-inch blade. This model features an axial glide system, saving space while delivering a smooth glide. It sports a large, soft-grip ambidextrous handle and upfront bevel controls for great usability. This saw is perfect for deck building and other large wood cutting projects.


This miter saw is a dual-bevel sliding model, which means that you don’t have to flip your material, unlike a single-bevel model. It boasts a larger cutting capacity due to the bigger blade so it is meant for tougher projects and materials.


Let’s take a look at the Bosch GCM12SD‘s specs – it has a 12-inch blade with a 14-inch cutting capacity (horizontally) and 6-1/2 inches (vertically). On crown molding against a fence with a 45-degree spring, it also has a 6-1/2-inch capacity. It has a 15-amp motor and a 3,800-RPM no-load speed. The tool weighs 65 pounds.

It has a bevel angle range of 47 degrees (left and right) with bevel stops at 0, 33.9, 45, and 47 degrees. For miter detents, it has stops at 0, 15, 22.5, 31.6, 45 (left and right), and 60 degrees (right), with a miter angle range of 52 degrees (left) and 60 degrees (right).

Vacuum hoses such as the VH1022, VH1035, VH1635, and similar 35-mm and 22-mm hoses are compatible with its dust extraction system while adapters such as the VAC002 or VAC024 are compatible for 1-1/4 and 1-1/2-inch vacuum hoses.


A 1-year warranty can be availed from the manufacturer, as well as a 30-day money-back guarantee to give you peace of mind. Either way, for improved durability, it is made up of stainless steel parts, even the miter scales. Its reliable dust extraction system is also a key factor in prolonging its motor and tool lifespan.


The Bosch GCM12SD boasts a lot of convenient features, such as a clear lower guard that makes it easy to see the cut for added accuracy. The soft-grip ambidextrous trigger handle will keep you comfortable for all-day operation. Thanks to the fence’s quick-release and lock feature, you don’t need to adjust it further, saving time and effort.

Due to the large bevel and miter scales, there’s a decreased chance of making mistakes with the measurement settings for your material. It also has a miter detent override that improves cutting accuracy. Moreover, you don’t have to reach behind the saw thanks to the upfront placement of the bevel lock.

Bosch GCM12SD Miter Saw in Use

Should You Buy the Bosch GCM12SD?

Are you working on big projects such as deck building? Is plywood among the harder materials you need to work on? Are you making furniture? Do you value cutting capacity over cutting speed? If you answered “yes” to these questions, I think that the 12-inch Bosch GCM12SD is for you.

Aside from its bigger blade and cutting capacity compared to most miter saws, its axial glide system will also save time, space, and effort due to the ease of sliding and adjusting while consuming minimal footprint on your work area.

If you are still unsure about the decision, go through the list below of pros and cons that I have gathered about the tool.

Pros of the Bosch GCM12SD

Let’s start with the good stuff.

It has an effective dust extraction system.

This miter saw has a dust chute that is compatible with 1-1/4 (using a vacuum adaptor) and 36 mm hoses so setting it up will be a breeze.

By having a convenient and reliable dust extraction setup, you can focus more on the material rather than the mess you made. After all, when dust gets in the way of cutting the material, the line of cut is usually blurred and can lead to mistakes when cutting.

What’s more, it’s not exactly friendly to the environment your lungs (even if you have protective gear) if you leave dust flying around your workshop.

Adjusting the bevel and meter is easy.

It has large bevel/miter scales so getting the right cut will be easier. It even has marked detents and roof pitch angles for your convenience. What’s more, it has a square lock quick-release fence so no adjustment is needed when aligning the fence to the table for support. It even has an upfront bevel lock so you don’t need to reach behind the saw.

The axial glide system minimizes the footprint.

The unique axial glide system minimizes the work area footprint while making it easier to glide the unit. This would appeal to workspaces that don’t have the luxury of space.

The handle is comfortable for all-day use.

A comfortable handle is usually self-explanatory – it will help you feel less fatigued after a hard day’s work. This is important for any vibrating power tool such as a miter saw but an ambidextrous trigger handle design is a plus for even more comfort.

Cons of the Bosch GCM12SD

Even though the Bosch GCM12SD is a great tool, there are a few cons worth noting.

The miter saw is on the heavy side.

At 65 pounds, the miter saw is not exactly portable. While it is okay for stationary use on a workshop or job site, it is not meant for transferring from room to room, such as with home remodeling jobs.

It doesn’t come with a laser guide.

Yes, this tool lacks a laser guide which can be a letdown for those who have an eye on accuracy. But don’t fret yet – an arbor washer laser guide sold separately (such as the LS010) is compatible with this tool, so you can simply DIY the miter saw to your preferences.

What Are the Alternatives to the Bosch GCM12SD?

Bosch CM10GD Compact Miter Saw - 15 Amp Corded 10 Inch Dual-Bevel Sliding Glide Miter Saw with 60-Tooth Carbide Saw Blade If the Bosch GCM12SD simply isn’t the miter saw you are looking for, I have alternative picks as well:

The DeWalt DWS780 (read my review) is a similar 12-inch miter saw that has a precise miter system due to the XPS crosscut positioning system for improved accuracy. It also has a 15-amp motor that runs at 3,800 RPM. Similar to the 12-inch Bosch tool I mentioned earlier, this model also has a great dust collection system.

For better usability, it has an LED work light to illuminate your cut to avoid making mistakes when working in dim areas. Its miter angle is similar as well, with 60 degrees to the right and 50 degrees to the left. However, a notable difference with this tool is that it has a higher vertical cutting capacity of 6-3/4 inches.

Another similar 12-inch pick I’d like to suggest is the DeWalt DWS779 (read my review). This unit is more lightweight at 56 pounds, a feature you will find useful if you feel that the Bosch GCM12SD is too heavy for your work setup. Similarly, it has a 15-amp motor with a 3,800-RPM speed.

Nonetheless, this model doesn’t come with an LED guiding light or a laser (you can buy it separately). It does have a good dust collection system similar to the previous DeWalt product I mentioned above due to the dust chute and port.

If you want a miter saw from the same manufacturer, a similar tool would be the Bosch CM10GD (read my review and comparison) , although this one only has a 10-inch blade. Regardless, all the features from the Bosch GCM12SD are found on this compact miter saw except for a similar blade size. If you feel very comfortable with the axial glide system, this is a good alternative if you only need to work with smaller projects.


To wrap it up, the Bosch GCM12SD is a miter saw worth getting if you’re into deck building and much bigger projects involving large pieces of plywood. This is a good pick if you already loved the 10-inch model from Bosch and just want a bigger blade. It has a lot of convenient features that will make your job easier while minimizing footprint.
