Bosch 12″ Dual-Bevel Slide Miter Saw Review

CM12SD Review


The Bosch CM12SD 12″ Dual-Bevel Slide miter saw came out early in the summer of 2015.  I have had a few months to use this saw on some projects.  This saw has quickly become my go to saw for quick, easy and accurate cuts.  We often talk about the right tool for the right job.  With miter saws I believe that it comes down to quick miter angle setup that are very accurate.  The CM12SD has far surpassed my expectations of accuracy and ease of use.

The bevel lever is very easy to open and lock with its location on the side of the saw.  The motor and gearing has been moved to give a greater cut capacity for trim and crown molding.  The turret bevel detent system is super easy to use and is very accurate with common detents at 22.5, 33.9, 45 and 47 degrees.  The multiple options for adjusting the fence and table extensions are simple.  No matter how you cut it, this saw will place in the top few miter saws made at this time.

Continued Development


Bosch has done a great job listening to users and creating a saw that woodworkers, trim carpenters and other trades will all want to use.  This saw combines the accuracy and cut capacity needed by the many different fields who use a miter saw in their shop or on the jobsite.   The CM12SD features many of the quality items found on other Bosch miter saws, but also has new items to help increase productivity and user comfort.  While that may sound a bit like a commercial, everything on this saw made me comfortable with the settings and knowing that once set, they would not move if the saw was bumped.  Maybe I am a bit picky when I deal with items like this because I have had the experience of working with some very inaccurate tools in the past while trying to create and build homes.  Those tools never were around long.

Favorite Items

Bosch_CM12SD_handleIn some ways, it could be the small things that make me know that a tool has been well thought out and brought to market knowing the tool does everything it needs to well without cutting corners.  The absolute first thing I found done right on the saw is the trigger safety.  This saw was one of the first that I have used in a while where I did not have to change my grip or even think about having to push a button to make the trigger work.  For both right and left handed people, this should be intuitive and comfortable.

The miter angles are easy to adjust and read with plenty of detents in the correct places.  Being able to quickly and easily change the miter angle knowing the detents are positive and accurate was an absolute joy.  There was zero slop in any of the detents and each measured out to be exactly as labeled.

Bosch_CM12SD_BevelWhen I moved on to bevel cuts, I found myself locking and unlocking the bevel lever just for the smooth feel of the cam lock.  I knew that no matter where I locked the bevel angle at, it was still there if I bumped the saw with lumber.  The bevel turrets are easy to adjust and pretty easy to read.  In bright light they could have black numbers, but overall I could always tell where they were set and that my bevels were locked in solid.




This saw costs less than $8.50 per pound and in my opinion is well worth it.  That is an odd way of thinking of this 65 pound saw, but it has been a pleasure to use over the last few months.  I have replaced the saw that was on my mobile stand with this unit because of how comfortable it is to use.  For any people, they will find this saw to be perfect for their needs.  The few that will not be happy will feel that way because of the dual slides that stick of the saw when retracted.  For workshops the Bosch GCM12SD Axial-Glide System might fit better, but owning that saw also makes me appreciate the bevel adjustments of the CM12SD.  The bevel locking lever gives me more confidence on this saw.  They do share a few similar features, but I like the accuracy and adjust-ability on this saw a bit more.

If you are looking for a nice trim or woodworking saw and have the room for the dual siles on the back, take a good look at this model.
