Summary: Bosch 3912
Comment: I have owned and have regularly used this saw for over three years. As others have pointed out it is almost impossible to get 100 percent accurate cuts from this saw. Tightening the lock down knob does push the blade out of alignment. The only thing you can do to improve this is to not over tighten the knob, but keeping the blade from shifting is still problematic. There is also some play in the blade which allows it to deflect slightly from the work piece, no matter how expensive or stiff a blade you use (worse when cutting hardwoods). But I've discovered that miter saws by their nature aren't accurate enough for fine work. To get extremely accurate crosscuts you need to use an accurately tuned table saw.

Summary: Bosch 3912 compound miter saw
Comment: The saw seems to be of rugged construction and needed only slight adjustments. My first test cuts were very disappointing using the blade supplied. After borrowing a much better blade from a friend and professional hardwood installer the next tests cuts were much, much better. I suggest that Bosch not ship such a cheap blade with the product. That is a disservice to the overall quality of the saw. I only gave a four star rating because I have not had the opportunity to use the saw much yet. I bought it to replace interior railings and trim in my house. Springs projects will start in a month or so.

Summary: Bosch 3912
Comment: Well made - like better than Dewalt or Makita. Plenty of power. Easy to set up - made no adjustments. Love the right or left handed operation - old school. No laser but I'm old and doing workwork for 40+ yrs. - wouldn't use anyway. Use on Denali Stand - very versatile.

Summary: Excelent value
Comment: I had searched, and researched for more than three months before making my purchase.
I read reviews, visited models in stores and talked with the guys at the wood working shops.
Finally I had it down to the Bosch 3912 and the Dewalt.
A side by side review, with 7-8 models including the Bosch and the Dewalt in one of my magazines really pushed me to the Bosch.
It is, and was the right choice. If I needed to do it again I would make the same decision.
I make furniture, and do finish work at home, and I have used a radial arm saw for years, and if you never have used a Miter you must have one...but expect to buy an up scale blade. If you want finish quality cuts you must have at least a 60 tooth blade, the more teeth the better. If you buy the saw...buy the blade at the same time unless you are just doing dimensional cuts that you will finish at the table saw. Quality blade = quality cuts. The 40 tooth that comes with the saw is only good for first cuts that will require finishing.
The one thing I would have liked as part of the machine is a laser guide.

Summary: Amateur Woodworker
Comment: This saw performs wonderfully. I have used it for floor molding, hardwood flooring, crown molding, small construction/framing projects, and now I am using it for some cabinetry projects.
The detent angle settings work great for the majority of the project. For the finer projects like cabinetry (or picture frames like another reviewer complained about) you will have to use a square to make sure the blade is at the exact angle desired in relation to the fence and table. Doing a quick check with a square or 45 before you do the critical cuts would be necessary on any saw and I have found that, now that I have made a few tweaks to the hard stops, adjustments are rarely needed. The blade is very decent and the saw has plenty of power.
I have not found a use for the work clamp other than using it to wrap the cord around when the saw is not in use. Maybe other people use it but I do not. After a lot of use, there is still no play in the blade bearings or anywhere else on the saw. The only down side about this saw is that it works so well that my Dad keeps borrowing it. He has his own craftsman that no longer gets any use.

What the Bosch 12-inch compound miter saw may lack in popularity compared to some of its competitors, it makes up for in quality design and construction. The saw has a heavy-duty 26-inch steel table that extends to 29 inches, and a tall sliding fence for working with crown molding and other large stock. While this isn't the lightest 12-inch saw available, at only 43 pounds it's still plenty portable, and comes with a cushioned top handle for easy carrying to and from the truck. Considering how solid and stable this tool is, and the amount of metal making up the base and table, we were actually surprised to find that it weighs as little as it does. The 15 amp motor on this saw, in typical Bosch fashion, runs remarkably smooth and relatively quiet. The electric brake stops the blade quickly every time. The miter gauge on this saw is engraved, so if the paint wears off you won't lose the markings or need to replace the saw. This is a great feature, and the Bosch saw is one of only a couple of saws on the market that includes it. It also features nine miter detents that can be easily overridden for micro adjustments, and we had no problem getting the table to lock in tight at a half degree off the detent. The saw has a comfortable horizontal D-handle, with a nice wide trigger and a safety switch inset in the handle right where your thumb can reach it. This saw offers all the accuracy and cutting capacity of other 12 inchers in a design that's easy and comfortable to use. Best of all, it comes with the Bosch reputation for solid engineering and smooth performance. The saw comes with a quick-action clamp, a directional dust chute, a dust bag, a 40-tooth carbide blade, and wrenches for adjusting the fence and changing the blade. -- Brian Trinen Choosing a Miter Saw
Miter saws are versatile tools that have become a mainstay of workshops everywhere. These powerful saws make angled cuts by pulling a circular blade down onto a workpiece with a short, controlled plunge. It might appear that miter saws are infinitely complex and varied, but there are only three general types. The type you choose will depend on your woodworking needs. Basic Miter Saws
Basic miter saws are the least versatile off the three major variations, but they’re a great starting point for novice do-it-yourselfers. These models typically adjust for miter cuts only, so consider upgrading if you need to do more than that. Compound Miter Saw
Compound miter saws are easier to use than basic miter saws because you can place your stock flat for cutting, and they adjust simultaneously for miter and bevel cuts. A compound miter saw is great for jobs that feature stock that's not very tall or wide, such as door and window trim or picture frames. Sliding Compound Miter Saws
Sliding compound miter saws are the most versatile of the available models. They have a motor and blade assembly that's mounted on a moveable arm to accommodate longer, wider workpieces. For smaller pieces, the saw performs like an ordinary fixed-head model. On some models, the blade can only pivot in one direction, but on a dual sliding compound miter saw, the blade can tilt to the right or left. Important Features at a Glance
Though models will vary by manufacturer and design, these are a few of the more commonly found features that you might want to keep in mind. - Electric brake: Reverses the flow of electricity when the saw's trigger is released. This is an important safety feature that slows the blade quickly in case of emergency.
- Blade guard: Most miter saws have self-retracting guards that withdraw when the saw is lowered for use, and reappear when it is raised.
- Laser guide: Gives a precise visual line where the cut will occur on your workpiece.
- Dust bag: Helps collect sawdust for a clearer, more tidy cutting area.
- Shaft lock: Immobilizes the shaft and blade for quicker, easier blade changes.
- Table extensions: Mount on either side of the saw to help balance longer workpieces.
Miter Saw Blades
Miter saw blades come in a variety of different sizes, grades, and materials, but there are three main types: steel, high-speed steel, and carbide-tipped blades. - Steel: Inexpensive and good for cutting soft woods or plywoods. Sharpness diminishes quickly in tougher materials.
- High-Speed Steel: More rugged than steel blades, and great for cutting harder woods.
- Carbide-Tipped: More expensive than other blades but much more durable. Maintain sharpness over a longer period.
