Key Features
  • 15 amp motor
  • Axial glide system
  • 3800 no-load blade speed
  • 52 degrees left miter capacity
  • 60 degrees right miter capacity

This Bosch sliding miter saw is slightly pricier than the two that occupy the first and second positions. That being the case, is it worth it? And does it justify the somewhat higher price tag?

To say that we were impressed with the saw’s design is understating it. It has a rather unique and futuristic design that we absolutely loved. But that’s not the only thing we liked about the saw.

Thanks to its axial-glide system, this one will come in handy in tight spaces. It does not take up a lot of space and makes it ideal for Jobsite use. However, we would not recommend moving it frequently as it is quite heavy, weighing 65 pounds.

Nonetheless, it does feature a powerful motor to compensate. The 15 amp motor is at par with other highly rated miter saws. Thus, you can expect smooth cutting of large pieces of wood with ease.

The saw has more moving parts than most of its competitors due to the addition of the axial-glide. However, the axial-glide system does not have exposed joint points. As such, it holds up well, even in a messy work environment.

Best 12-inch compound sliding miter saw buying guide

Single vs. double bevel

Compound miter saws can either be single bevel or double bevel. A single bevel saw head can only be moved in one direction, either right or left. In the case of a double bevel, the saw head can be moved in both directions.

For decorative works, you will need the best 12-inch dual bevel sliding compound miter saw. However, these saws tend to be pricier than single bevel. Thus if you are a hobbyist, a single bevel compound miter saw can still be a good option.


A miter saw should be powerful enough that when you lower the blade, it cuts through the material with ease. If you find that you have to apply extra force and pressure to cut through a piece of wood, it isn’t powerful enough.

The standard of measuring how powerful a miter saw is is how many revolutions per minute it makes. For most standard works, a 3800 RPM is sufficient.

Direct drive vs. belt driven

The motor is responsible for the blade’s revolutions per minute. There are two ways power is transmitted from the motor to the blade, direct drive and belt drive. Direct drive means the motor is directly connected to the blade hence more power.

Belt drive means that power is transmitted with the aid of a belt. Belt drive saws have their advantages, but if its power you are after direct drive is the better option.

Ease of use

Overall, you don’t want to spend ten minutes trying to figure out how to use a sliding compound miter saw. As such, ease of use is another crucial factor to consider. The bevel and miter scales should be clearly marked.

This way, you can make the necessary adjustments when cutting any material. Also, the blade should be easy to change in case you need to swap out the default blade.

Dust collection

Miter saws produce lots of sawdust when in use. Sawdust can interfere with your ability to make accurate cuts. Also, sawdust poses a health risk in the workshop, especially if it’s a small workshop.

As such, it is essential to consider the dust collection capabilities of a saw. The best 12-inch sliding miter saw will typically have some sort of a dust collection port.


Compound miter saws can be bulky, with some weighing upwards of 88 pounds. This is because they are typically designed to be stationary. However, you may want a sliding compound miter saw to use in a job site.

In this case, you will want a saw that weighs a little bit less. Some saws weigh 50 pounds, making them capable of being carried.
