People Also Asked  About For Bosch GCM12SD

Does the Bosch GCM12SD have a laser?
The big missing thing in this otherwise excellent miter saw is a “DUAL LASER GUIDELINE”. A dual laser guideline makes it faster to set the saw on the cutting mark providing more precision. It would be nice if Bosch would actually darn laser on these saws, especially because it isn’t cheap but lacks laser guidance. However, one can buy the Bosch LS010 Miter Saw Laser Washer Guide separately, which is designed to be used with the Bosch miter saws.
What blade comes with Bosch GCM12SD?
The Bosch GCM12SD bundles a 12-Inch 60 Tooth fine saw blade which is capable to holds up through anything from the ground to the crown. It can safely accomplish cutting off hardwood boards that are beyond the ability of smaller saws.

  • 14-inch horizontal cutting capacity

  • Easy to adjust, visible Bevel detents
  • Upfront miter and bevel controls
  • 15-amp motor, 3800 RPM powerful motor
  • 2 Durable and precise quick-release fences
  • Difficult to use the on-off button
  • Too big fence for cutting smaller pieces
  • Slightly hard to move around


Get ahold of the user manual and carefully read the instructions written on the provided user guide carefully when setting up and before operating the miter saw.

Unpacking and Checking Contents

Slowly remove the tool from the packaging material by carefully reaching down to the two side carry-handle locations, and steadily lift until it clears the package. Never lift the miter saw by gripping any component other than handles.

Attaching Loose Parts

There are usually few small parts like miter lock along with lock knob and bevel lock lever which is supplied in loose and has to be attached before the saw can be used. You have to look and identify these loose parts from user manuals and install them as per the directions given.

Removing and Installing Blades

The saw is generally supplied with a standard blade installed within. However, some users require different blades for specialized needs. In such cases, you should remember to always use a blade of the same size/diameter as the one provided with the saw and follow the instructions given in the user manual. Once you have installed a new blade, make sure to check it for not being obstructed by the table or blade guard.

Assembling Dust Collection System

The last thing to do is to assemble the dust collection system by attaching the dust collection bag with the coupler/port.  Having attached the bag, the first thing to do is making a “dry cut” by presetting the miter and/or bevel angles of the unplugged tool and practicing the cut before turning it on.

You should empty the dust collection bag once it is two third full by carefully removing the bag and pulling open the zipper on the bottom. You have to shake the bag vigorously to vacate it properly after which you can close the zipper and reattach it according to the provided manual directions.


Miter saws are dangerous power tools and could cause accidental injuries if used carelessly or casually without precautions. Some of the safety measures you need to consider when operating both these miter saws (in general all miter saws):

  • Always wear hearing protection and safety glasses or a face shield
  • Use a proper dust extraction mechanism else wear a respiratory mask
  • Don’t wear loose clothing or dangling jewelry
  • Always use the safety guard when operating the machine
  • Hands and fingers must steer clear of the blade
  • Whenever adjusting the blade or doing repairs, always unplug the saw from the power outlet
  • Frequently clean the lower guard for clear visibility
  • Always use the appropriate fitting blade size
  • Ensure that the fasteners and the blade is properly positioned
  • Use a material clamp to hold the material securely against the fence
  • Release the trigger once you are done with cutting


  • Bosch’s GCM12SD has a unique axial-glide mechanism instead of a conventional two-rod slide system making it compact than DWS780
  • As opposed to GCM12SD which is compact and can be fitted over a 24-inch workbench, DEWALT’s DWS780 needs larger space and require a 36-inch workbench
  • Sawdust piling affects the two-rod sliding system more and GCM12SD clearly is better in this term
  • GCM12SD has a better angled-cut capacity as compared to DWS780
  • Dewalt DWS780 features and exclusive XPS cross cut positioning system while any such mechanism is absent in GCM12SD
  • DWS780 has a larger horizontal and cross-cut capacity than GCM12SD
  • DWS780 has a maximum of 49 degrees bevel angle as opposed to GCM12SD’s 47 degrees which have a slightly larger left miter angle than the other
  • At 56 pounds, DWS780 is a whole 9 pounds lighter than GCM12SD
  • DWS780 offers a better pledge in comparison to GCM12SD
  • GCM12SD is a little expensive than DWS780


  1. GCM12SD and DWS780 have powerful 15-ampere motor to deliver no load 3800 rotations per minute (RPM)
  2. Both are designed to accommodate a 12-inch blade
  3. Both have 60 toothed carbide-tipped blades
  4. Both have similar miter and bevel ranges
  5. Both are ‘CE’ certified


However, Both GCM12SD and DWS780 are pretty much different from each other, each one having its own pros and cons. But both the dual bevel saws are equally up to the mark, adaptable, easy to use, and equally easy to move around as per requirement.

Both are using the same razor-sharp 60-tooth carbide-tipped blade that helps achieve higher cutting efficiency as the greater number of teeth means spiked edges so they start off sharper and continue cutting sharp throughout the cut with less chipping and a higher feed rate and are a much better alternative than steel ones.

When it comes to cutting capabilities Dewalt excels and is a better than Bosch miter saw, so we’d say out of them both, DEWALT DWS780 is a better bargain.

Final Thoughts

Choosing either one of them could be complicated as both are renowned industry power tools manufacturers, and both try to keep up with their name and reputation by continuously offering their consumers new and upgraded versions of their previous power models.

The detailed inquiry of both these miter saws including their price, cutting capacities, operations, and safety, warranty, and package inclusion further confirms that these power tools speak of brilliance and accuracy, but go with the one that matches your work aptitude.

Dewalt Vs Bosch, Tough Choice…

Good Luck!!!
