Our Bosch GCM12SD Review

Cut Quality

Accuracy and cut capacity are some of the most notable strong suits of the GCM12SD.  One of the innovations that lends itself to accuracy on this saw is the Axial-Glide System.  This system was designed with perfect alignment, ultra-smooth cutting action, and hyper-accuracy in mind.  On top of all that, the Axial-Glide System saves space because it doesn’t use a traditional rail setup.

This saw can make just about any cut you want.  It has a 14-inch horizontal capacity, and a 6-1/2-inch vertical capacity.  To up the cutting capacity even more, the GCM12SD has two sliding base extensions that offer enhanced support.

Ease of Use

This saw is surprisingly intuitive and easy to use for how powerful it is.  First off, it features Squarelock quick-release fences for simple and precise alignment.  Even more convenient, these fences have a one-touch lock/unlock feature that makes alignment even easier.

One of the more appreciated aspects of this saw for ease of use is the all-metal bevel lock lever and range selector located in the front of the saw.  This means you can make bevel adjustments without having to reach around the back of the saw.  The bevel range goes from 0 to 47 degrees to the left and the right, with marked detents at 0, 33.9, and 45 degrees for both left- and right-facing cuts.

To top it all off the GCM12SD has a clear lower guard to so you can see the cut you are about to make.


The Bosch GCM12SD sports a 15 amp motor that delivers no-load speeds of 3,800 rpm.  This kind of power provides fast, accurate cuts easily.  You can trust that Bosch built this machine with quality and longevity in mind, it will keep going, and going, and going.


As always, you can count on the reputation Bosch has built over the years to provide quality control as well as solid customer service if anything goes wrong.  This particular saw has a 30-Day money back guarantee as well as a 1-Year warranty.

Overall Value

The high ratings across the board make arguing against the value of this saw extremely difficult.  It is certainly in the higher-end price bracket, but so are comparable miter saws in it’s class.  The truth is, most of the time you get what you pay for—with this saw you might even get more than you pay for.  Especially when you consider how much darn work you can get done and how painless that work can be.

Our Verdict

If you are in need of a reliable miter saw that can handle just about anything you could possibly throw at it, but don’t want to sacrifice comfort or ease of use, this saw might be for you.  It would be suitable for professional contractors as well as serious D.I.Y. woodworkers—and everyone in between.
