Miters saws are one of the most time-saving tools you could own. Their versatility makes them an excellent choice for performing intricate straight cuts through wide pieces of lumber. Compound and sliding compound miter saws take it several steps further and give you the ability to cut on two planes through wider boards.
The Bosch CM10GD goes beyond what a regular sliding compound miter saw can do. It comes with space-saving features that significantly reduce the amount of required clearance to draw the saw head forward. Now let’s see what else the CM10GD is packing.

You might be wondering why the CM10GD isn’t called a sliding compound miter saw. After all, the saw head “slides” forward and backward to increase the saw’s cutting capacity. However, the saw head doesn’t slide like in sliding miter saws, but instead, it is directed by a gliding arm.
The main difference between “sliding” and “gliding” is that the CM10GD’s axial-glide arm doesn’t require the use of long rails that protrude from the back-end of the tool. This means you can push this tool up against the wall without having to worry about whether or how far the saw head can move.
One feature that most people overlook is the fence. The CM10GD has a two-piece fence; a fixed lower fence and an extendable upper fence. The markings on the fences are easy to read for precise repetitive cuts. However, the design of the saw has one major flaw in regards to the design of the fence. While the extendable fence is closed (not extended outwards), then it’s possible that the saw blade can cut through it. This is, in our opinion, a major flaw that the operator needs to be aware of as not to cause any damage to the unit.
Due to the mitering and beveling nature of this miter saw, there is a wide range of different cutting capacities to take into consideration.
First, with the saw head positioned at 90°, the 10-inch blade can cut boards up to 8 inches thick and 12 inches wide. When angled at 45° in either direction, the saw can crosscut boards up to 8 inches wide. While the blade is tilted at 45°, it can blocks up to 4-1/2 inches thick.
It’s not uncommon to find that the miter gauge needs some fine-tuning to get the saw head at the desired angle. However, that is not the case with the CM10GD. Straight out of the box, the CM10GD’s miter gauge will be perfectly set so you can get straight to making compound cuts.
The miter gauge has positive stops at 0°, 15°, 22.5°, 31.6°, and 45° in both directions. There are also positive bevel stops set at 0°, 33.9°, and 45° to the left and right.
It’s extremely important that you keep your miter saw free of sawdust at all times. When dust goes airborne, it can settle underneath power tools which could become a fire hazard. The CM10GD comes with a collection bag that captures 90% of the produced sawdust. There’s also a 1-1/4-inch dust port to connect a shop vac.
Despite all of the CM10GD’s features, there are some pretty significant drawbacks to this tool.
The first thing we noticed is that the axial-glide arm doesn’t is a bit wobbly. This translates into imperfect straight cuts which could ruin the cut-edge of your board. The arm moves straight when it’s coming forward (toward the user) but then angles slightly away as it retracts.
Another thing we’ve found is that the dust collection bag doesn’t seem to want to hold onto all of the dust. It’s a bit too porous and leaks sawdust everywhere behind the tool. If you get this tool, we recommend connecting a shop vac for maximum dust collection.
Something that all professional handymen are looking for is portable tools. The CM10GD weighs 65 pounds which is quite heavy by portable miter saw standards. However, keep in mind that this tool has a small footprint so it won’t take up too much space when loading it onto your truck. To increase the tool’s portability, you can get the Bosch folding miter saw stand (sold separately) which comes with caster wheels for easy movability.
There’s no denying that this is a great miter saw from Bosch. The lightweight, compact design makes it a noteworthy sliding/gliding compound miter saw for professional and hobby use. There are some rather significant downsides, such as the angled retracting trajectory of the saw head and the fact that the saw can end up damaging its own fence. However, with extra care, this could be an extremely valuable tool for your workshop or to take to the job site.
