        Does this saw have a depth of cut setting that can be used for half-lap joints?
        ByAug 8, 2026
        1 Answer | 
        Answer This Question

        Hi! Thank you very much for your question. Yes. The CM10GD features a Depth of Cut Adjustment, which allows the blade depth to be set for non-through cuts rather than cutting completely through the material. This feature can be used when creating half-lap joints, grooves, and similar applications where a controlled cutting depth is required. For further assistance, you may email us at bosch.tools@us.bosch.com or contact us at 1-877-BOSCH99 (1-877-267-2499) from Monday through Friday, 7 a.m. to 5:30 p.m. CST.

          will the DeWalt stand work
          ByJul 31, 2026

          Answer This Question

          Hi! Thank you very much for your question. The GCM12SD is designed to be compatible with standard miter saw stands. However, since the stand is manufactured by DEWALT, we recommend contacting DEWALT directly to verify compatibility with your specific stand model and mounting system. This will help ensure a proper and secure fit.

              How can you make such a good and high technology tool and you you don't add shadow line or laser??? Would that really increase the price ?? I was about to get it. Pitty. That is a deal breaker! Very disappointed!

              Don’t let the Bosch answer to your question fool you into thinking they haven’t gotten this feedback for years. It defies logic they have not added this feature. They would literally sell 2x as many of these saws.

                Bosch was the first manufacturer to offer a laser on their miter saw. Professional carpenters, millworkers. and cabinet makers did not like the feature the majority of the Bosch purchasers are professionals they discontinued the laser feature.

                  Hi! Thank you very much for your question. We’re very sorry to hear about your disappointment, and we sincerely apologize for the frustration this caused.

                      This is an excellent miter saw with all the adjustment for the miters and bevel angle changes in the front of the saw. The only challenge is getting the dust collection port to connect to a Vacuum like a DeWalt. The Bosch vacuum likely attaches but if a dust separator is used the hose compatibility is a bit challenging. Otherwise this saw comes already calibrated with everything square both on the horizontal and vertical planes. Attaching it to a plywood work station is very simple. This saw has lots of power and can do wide boards! This is the second one have bought this one for my son. Excellent saw!

                      Purchased this saw for a dedicated miter saw in a woodworking shop. Happy with the smooth movement when cutting. It does not have a laser but I was able to add a shadow line using an aftermarket product. Very happy so far

                      This is replacing an old Hitachi saw. The movement is incredibly smooth. Power is excellent. There is no bog down in any type of wood. The controls are slightly fussy at first, but you get used to them. At first, I didn't see positive stops at 0 and 90 for the bevel, but they are there.

                      The Bosch 12” Mitre saw is outstanding in performance and the glide system is awesome, and allows for the saw to be mounted close to the wall, saving valuable space in a small shop. The only drawback I have had is the dust collection could be leaps better. I would recommend the mitre saw to a friend and only suggest the dust collection be better and add a laser or straight line light.

                      Arrived clearly opened and used. Sawdust all over it. Was sold as new. Arrived very out of alignment, but that’s expected. Used when sold as new is NOT expected.

                      Buy Once Cry Once
                      Bought this saw a few months ago for a home renovation project. Since then I’ve come to a few conclusions about this saw. This saw is well packaged and easily recyclable material. Heavier weight gives it a more in a shop feel than a jobsite saw. Amazing ergonomics and powerful. Easily mitered 6x6 PT posts in 2 cuts. One gripe is the safety on the trigger could be easier to use. All around amazing saw and glad to have it in my arsenal.

                        Best compound miter saw I’ve had. The arm movement is so smooth. It cut perfect right out of the box. I suggest getting the Bosch stand as well.

                        Great miter saw
                        Overall this is a great miter saw. I do have some complaints though. First of all, it was square right out of the box. There was minimal setup involved. The gliding mechanism didn't need adjusting. It was very smooth. There is one issue I am noticing. The cuts aren't clean. The blade makes a weird sound. As soon as I hear the sound, I know the cut's going to be off. The blade seems to wobble. The funny thing is that it doesn't always happen. I will make some adjustments to see if I can correct the issue. Also, I knocked off a star because, for the price of this saw you'd think they could include a stop on the extension wings. This saw is replacing an old 10" craftsman miter saw. The only thing that saw had that this one doesn't is the axial glide. I'd expect Bosch to have thought about including that and not make it an after purchase accessory.

                          Cheap metal for locking mechanism.
                          I have a custom woodworking shop and have used DeWalt and Hitachi sliding compound saws daily for the last 6-7 years without any major issues. Decided to go with the Bosch this time because of the reviews and the sliding mechanism they designed. We only had the saw for 10 days and the knob that locks down your angle in the front completely snapped and split the metal base where the boards sit. Did not over tighten, it snapped with just being snug. Wouldn't recommend for more than a hobbyist tool

                            Bosch miter saw is almost perfect except it misses shadow line or laser. To build one, you need Dewalt N030317 Work Light, 5V AC to DC converter at least 0.45mA (1.5"L x 0.77"W x 0.6"H), a switch (or one from Dewalt Miter Saw Power Supply N078832)
