Its earned a solid reputation among pros, DIYers, and beginners, mainly because it often incorporates many useful features that you’ll find yourself relying on each and every time you pick up this saw. This model isn’t just flash. Instead, it’s all about functionality, ease of operation, and features that can make a world of difference in terms of cutting speed and accuracy. This model’s glide system, impressive cutting capacity, and simple controls make this model one of the most user-friendly miters on the market.

Product Rating: (4.5/5)


  • Powerful motor
  • Handle designed for right-handed and left-handed users
  • Great dust collection system
  • Highly adjustable cutting action
  • Compact design
  • High cutting capacity


The saw’s unique build is what makes it so highly portable, so you can easily transport it or store it when not in use, making it a great buy for those who don’t have much space to work with in the garage or workshop.

The cut capacity and accuracy are both this saw’s strong suits. The axial glide system is one of the innovations that lends itself to the saw’s accuracy. This type of system was designed with hyper-accuracy, incredibly smooth cutting action, and perfect alignment in mind. The system will also help to save on space since it doesn’t feature a traditional type of rail design. The saw can easily be bolted down or clamped down to your workbench. Its fence is another notable feature that can be adjusted by using the unlock button located on either side. This is a true fence that comes with a square lock feature to ensure it’s always at ninety degrees.

The length of the table can also be adjusted to a max of forty inches, which is perfect for users who often work with longer material. Weighing in at sixty-five pounds, this model is pretty heavy, especially if you plan on transporting it often. Because of this, I recommend forking over the extra cash for a compatible saw stand if you plan on using this saw for work purposes.


The saw’s handle is D-shaped and designed for both right-handed and left-handed users. Most lefties will definitely appreciate this design since it works to improve user comfort and control. The handle itself is very grippy, making it easy for users to comfortably hold it as they stabilize the saw during use.

Cutting Capacity

This model offers a higher cutting capacity at fourteen inches horizonal and six and a half inches vertical, with a six and a half-inch crown capacity. The saw is able to handle pretty much any type of cut. To increase the cutting capacity further, it features a couple of sliding base extensions for improved support.


A saw that’s this adjustable allows users to make a wider variety of cuts, which is exactly what most buyers are looking for. But while the saw itself may look complex and intimidating, adjusting this saw couldn’t be easier, thanks to the marked detents, stainless steel miter scales, and uniform bevel. This model offers bevel detents at zero, thirty-three degrees, and forty-five degrees right and left, for improved cutting accuracy.

Cutting Guide


The fact that the manufacturer didn’t add some type of cutting guide is a surprise, since they seemed to have gone all out on the other features. The lack of a laser or LED cutting guide can be a drawback for some potential buyers, especially beginners. The SKIL 3821-01 12-Inch Quick Mount Compound Miter Saw is one of the top competing miters and it features the popular laser guide that’s designed to improve cutting accuracy and it’s definitely a feature that makes the saw more beginner-friendly. The lack of a cutting guide on this Bosch model will be a big disappointment for some.

Dust Collection System

The built-in dust port is compatible with a wide variety of hose sizes and has a reputation for being one of the most efficient dust collection systems of any model in this price bracket. A strong dust collection system is crucial to safety since it works to keep your workspace and workpiece clean and free from debris. This improves user visibility and allows you to quickly make cuts, without needing to frequently clean off your workpiece.


This three HP, fifteen amp motor delivers a no load speed of three thousand, eight hundred RPMs. This type of power is designed to provide accurate and fast cuts. The power it offers is better than average for a model of this size. In terms of durability, the motor is efficient, reliable, and powerful. You won’t have to worry about the motor overheating during extended use.


For a pro-quality model, it’s surprisingly easy to use and very intuitive. It comes with a square lock quick-release fence for precise and simple alignment. These fences have a one-touch unlock and lock feature that makes alignment fast and simple. On the saw, everything that’s red can be adjusted. The knobs are made out of a tough plastic and don’t have a cheap feel. The saw can lock into a down position for transporting or it can lock into place for chop saw work. If you’re using the saw with rails then you’ll be impressed by how easy it cuts and smoothly glides. If you don’t like how loose the glide action feels then you can take advantage of the tension adjustment arm, which can be used to make the saw a little stiffer. Basically, this versatile saw allows you to make several adjustments for a more customized feel.

Advantages and Disadvantages


  • Compact design
  • Excellent dust collection system
  • User-friendly
  • Highly customizable cutting action
  • Handle designed for right-handed and left-handed users
  • Powerful motor


  • Does not come with a cutting guide
  • Does not come with a saw stand

Bosch Versus SKIL 3821-01 12-Inch Quick Mount Compound Miter Saw

The competing model by SKIL features a laser cutting guide, unlike this model by Bosch. However, laser cutting guides cannot be used in bright sunlight, since the light makes it difficult, if not impossible to see the laser. In terms of power, the competing model offers slightly more at four thousand, five hundred RPMs and a fifteen amp motor. Like the Bosch, the SKIL is considered highly portable, so it’ll be a great choice for pro use, however, it lacks the type of adjustability that makes this saw by Bosch such a success.

Conclusion and Rating

Product Rating: (4.5/5)

BoschWhile it’s not perfect, it’s pretty close. This highly adjustable saw allows you to fine-tune each setting based on user preference and the type of material you’re cutting. Making adjustments is fast and simple, which is why it’s such a great buy for users of all skill levels. If you’re looking for the best 12-inch miter saw, one that can handle anything you can throw at it, but you don’t want to sacrifice ease of use or user comfort, then the Bosch Power Tools GCM12SD may just be for you. It’s a great choice for the professional, but it will also be a solid investment for the novice, woodworker, and seasoned DIYer. I gave this model a rating of four and half out of five stars.
