Bosch GCM12SD 12-in Dual-Bevel Glide Miter Saw Review

Bosch GCM12SD 12 " Dual Bevel Glide Miter SawI can’t say which was the primary reason Bosch developed the glide mechanism for this saw, whether it was to make the action smoother or save all the space that’s usually taken up by rails hanging out the back of a sliding saw. But when the Bosch GCM12SD 12 inch Dual Bevel Glide Miter Saw came out, both were accomplished.

Every single buyer who has reviewed this innovative saw has commented that both the up-down and in-out action of it is smooth and effortless. Some even said TOO smooth and effortless – Bosch fixed that problem by adding a tension adjustment so you can tune it to your liking.

The patented Axial-Glide pivoting arm system also saves you up to 12” of space behind the saw, making it ideal for using it in a shop setting – you can actually set it up on a 20” deep bench just a couple inches from a wall.

Other Features:

  • Up-front bevel lock and controls so you don’t have to reach around the back of the saw
  • Integrated base extensions that pull out to increase support to up to 40” and can be locked in at any position
  • Tall quick-release fences that can be slid out to the same reach as the base extensions for superior support and more accurate cuts
  • A handy little length stop that can be attached to either extension for repetitive cuts
  • Thumb actuated push button miter detent override right there in front of the handle/locking knob
  • Easy-to-read etched stainless steel miter scale and equally clear bevel scale and indexing on the fences
  • The dust collection chute will mate up to a vacuum hose in 1-1/4” or 35mm size to keep your work and your work area clean

What Buyers Have To Say

On the CPO Bosch site (where I recommend buying)  there were 5 buyer reviews, 2 gave it five stars, 2 gave it four and one had some problem with it and gave it two.

One cabinet maker had this to say:
“The saw is perfectly balanced and is very smooth to use. It makes very clean, exact cuts. The unique glide arm is worth every extra penny it cost — both in balance/ease of use, and the workbench space savings. Highly recommend this saw, it’s certainly well worth the investment.”

On Amazon, there were 30 reviews, 16 of them five stars and 7 gave it four.


There are two shortcomings I see and wouldn’t you know it, they’re the two most often mentioned by the buyers who didn’t give the GCM12SD five stars.

First off there’s a problem with the drive housing getting in the way on the right side. If you try to bevel 45 degrees to the right, you’re limited to 1/12” of thickness and mitering to the right, it’s something like 4-1/2”. What really bugged a few people is the Bosch literature claims you can cut molding up to 6-1/2” up against the fence but didn’t mention is has to be a square cut or mitered left.

The second glaring shortcoming is the lack of a laser guide. For a saw this advanced and in this price range, that’s just odd to me. Bosch does make an  arbor mounted, battery operated laser (optional, extra-cost) but it’s not very bright, only works on one side of the blade, and the batteries don’t last. Oh, and unlike saws like Makita’s, it only comes on when the blade is spinning so it doesn’t help you set up your cut before triggering.

Less of a problem is the issue of weight. Bosch says this saw weighs in at 65 lbs but a couple of buyers have mentioned figures like 80 and 88 lbs. If the buyers are right, it’s not very portable but still an excellent shop saw.


This a super-innovative machine, smooth operating and accurate. If you don’t need a laser and don’t have to cut tall stock mitered or beveled to the right, this is a definite yes. Expensive, but most owners love it.

Where To Buy

I’m definitely going to recommend buying this saw from CPO Tools. It seems a lot of people who bought from the big company that starts with “A” had major issues with the saw being damaged in shipment. And one of them said if you’re going to order this saw get it from someone who uses FedEx, not UPS. CPO uses FedEx.

At CPO Bosch, the price is right, shipping is cheap and if you’re so inclined, you can buy a factory reconditioned saw at a $120 saving. Since it won’t come with the mediocre blade the new one does, you could use the savings to buy the blade you know you want to buy for it anyway. Or put the savings toward a Bosch miter saw stand, either the folding leg model for $249.99 or the vastly superior Bosch T4B Gravity-Rise Wheeled Stand. That one would actually make this big saw very portable.
