Our Bosch CM12SD Review

Cut Quality

This 12″ miter saw offers the power and accuracy you might expect from Bosch.  It was designed to give users wide cut capacity and the versatility to get almost any job done. For most general purposes this miter saw comes ready to be put to work.  For finish work and more delicate applications, some minor adjustments are recommended per usual.  To take this saw’s cut quality to the next tier, upgrading to a 80+ tooth finish blade is recommended.

Owners of the CM12SD report that it’s simple to use and produce great cuts.  True miter and bevel angles support consistently accurate cuts.  Even without adjustments or upgrades, this miter saw delivers quality cuts again and again.

Ease of Use

Although this miter saw comes ready to be put to use, most craftsmen (should) know how important adjusting and calibrating is.  Making adjustments is easy with the Bosch CM12SD.  Simply undo the lock nut, and turn the screw in either direction for the necessary adjustment.  Long-time users report that calibration remains consistent over the years, even after considerable use.

This miter saw was engineered with many features that make it a breeze to use.  The high-powered 12″ blade makes for butter-smooth cuts (more on that below) by itself.  Bosch increases ease of usability with a number of helpful features.  A dual bevel range of 47 degrees on both sides and a tall 4-3/4″ fence design allows for just about any cut you could need.  The electronic brake enables quick cutting, without sacrificing safety or accuracy.  And an exclusive-to-Bosch quick select turret bevel stop system has positive stops at 22.5˚, 33.9˚, 45˚, 47˚.


The Bosch CM12SD-RT doesn’t trade toughness for anything; the majority of users are beyond satisfied with the durability of this miter saw.  It comes ready-to-go, designed to take all the abuse that you can throw at it.  This 12″ saw boasts a 15 amp motor that ensures you’ll never be without the power you need to get the job done.

Overall Value

The CM12SD is undeniably a popular power tool.  You can find it on work sites all over the world.  Many users who bought this miter saw with the intention of using it as a backup, said that the CM12SD became their primary miter saw.  When you consider the accuracy, durability, and long-lasting ease-of-use, it’s not hard to see that this miter saw is worth it and that goes double if you’re able to save money on the refurbished CM12SD-RT.
