  1. Harris Renovations LLC

    Ahh… The Bosch GCM12SD, what can I complain about?I’ve been in the construction industry for 26 years. I’ve used almost every tool brand out there. I’ve used almost every size, shape, color, and flavor of miter saws. After starting my own business, I needed a miter saw. But, which one? I knew I liked Bosch tools from experience. I also knew my budget didn’t allow me to start with something like DeWalt and work my way up to Bosch. I took a one-time chance with this saw and I haven’t quit… Neither has this saw.After years of chopping up everything I can throw at it, it hasn’t missed a beat. From fragile solid maple inlays to railroad ties, this beast knows no limits. 60-degree angles on 4×6 posts for a landscaping triangle would make most miter saws throw in the towel. Not this one. It made those cuts like butter.I’m tired of inaccurate ratings and reviews. “my item didn’t arrive on time, 1 star”, “the carrier appears to have dropped my item off of a 48 story building into a pool of lava and now it doesn’t work, 1 star”… You know what I mean?Let me make this as helpful as possible.Anyone who has used a sliding compound miter saw knows that the dust it produces causes the slide mechanics to gum up, restrict movement, and inevitably cut fingers off. Bosch takes care of this problem with their axial-glide system. Mine is still as smooth as the day I got it. No longer do you need a foot and a half behind the saw for the slide mechanism to work. The glide just kind of folds and unfolds. I’m still impressed with the way this system works.No, this saw doesn’t come with a laser, crown stops or someone to lug it around for you. If you need these items, you’re in the wrong business and don’t need this saw. Although mine was made in Malaysia, I’m sure it’s now made in China. What isn’t? That doesn’t mean it’s some cheaply made pile of junk knockoff.The saw does come with a blade. Unfortunately, the blade is only good for throwing at trees. (WARNING! Don’t do that). Do yourself a favor and invest in a few Freud Industrial blades. My favorites are the 60T for the “not-so-delicates”, and the 72T for detailed work.If you plan on using this saw to move from jobsite to jobsite, you’re going to need a stand with wheels. Although you can fold these stands up for storage, it’s almost a two-man job to do so. I never fold mine. This saw is heavy and awkward.There’s really not much else to say about this work of art. It does what it’s supposed to do without question. If it fits your budget, buy it. If you make poor choices or your favorite color is yellow, you know where to go.In closing, the only complaint I can think of is that it doesn’t bring me a beer at the end of a job well done.

    If you’re looking for a great shop saw, and you can afford this one, you won’t be disappointed. I’ve used a lot of miter saws and this is the best one I’ve had. It can play a large role in the shop. I use mine in the shop but I’m sure it can be portable. However, it is a large saw so you will need the contractors portable base. The only drawback is the dust collection system on it. It could be better, but you can rig up additional methods that work well. Bosch hit a homerun with this one.

  3. David A Smith

    This is my first impression after buying the saw and setting it up. Accuracy is dead-on out of the box. I made several cuts in 2×6 yellow pine. All were square both ways. The cut was good with the Bosch blade, even better when I installed a Freud 96-tooth blade from my old miter saw (blade change was easy–just follow the instructions). Dust collection is a challenge, but I modified my old miter saw cart and added my Festool vac to the mix. What the vacuum doesn’t get, the shroud on the cart does. I only have to turn on the shop vac that’s connected to the cart. The Festool comes on automatically–so I only have to start one vac, same as I did with the old saw. The Bosch saw replaced a Dewalt (I think it was a 714). The Bosch seems to run smoother and cut without straining as much as the Dewalt did. I saw some YouTube videos slamming the Bosch for not being accurate or having too much play in the sliding mechanism. Maybe parts will wear out, but out-of-the-box there is no play anywhere–everything works smooth and tight. Some reviews complain about the weight. I had no trouble moving the saw around, and I’m a 65-year-old plugger who’s by no means buff.

    Going from my 20 year old Makita, to this new “Glide Miter” is very cool! After calibrating, (insuring all cuts will be accurate!), this saw is a gem! so many years of being a high end trim carpenter, and custom furniture designer and producer, even as a child in my dad’s hobby shop, I learned early on that precision cuts are a necessity! I’d never thought any compound sliding miter could replace my Makita, it being tried and true even compared to so many other saws on the market, and those saws used in the field, (co-workers in fine trim carpentry skilled trade), I’ve have many times used another saw for being convenient, finding them just barely suited for exacting cuts, the need to be more so careful in making cuts as compared to the Makita, but with the Makita starting to fail in regards to so many years use, and its brake failing, I decided to pro-act, rather than wait for its demise at an inopportune time, I purchased this new type of Glide, vs Slide, compound miter.. I couldn’t be pleased with cutting results, ..Hands down, the finest saw I’ve ever used!

    I’m not going to sugar coat it, this saw is badass. The stock blade is pretty coarse but it cut base molding well as well as 2×8’s and 3/4” plywood. The saw is super adjustable and leans to both sides for miter cuts. The crazy multi arm slide is smoother than any slide type saw I have ever used including other Bosch saws, Rigid or Dewalt. It’s not cheap but if you want the best heavy portable miter saw available this is the saw.

  6. Glenn Smith

    We have had the saw for about three weeks. It arrived via delivery without any damage. Before purchasing this machine I researched Milwaukee, Hitachi, Freud, Dewalt, Makita, Festool & Jet saws. Here in Columbus we have a Woodwerks store that features Festool and I was given a hands on demonstration. At $1,400 it seems to be a great machine. But, the Bosch is also a great machine and the there is a substantial price difference. My Son and I have a cabinet shop and needed something to replace my 35+ year old Makita Model 2401 10″ miter saw. For some time we have been cutting off hardwood boards that were beyond the ability of the small saw to accomplish safely. For over a year I was considering this machine. But at $750 I wanted to be sure it was durable, accurate with repeatability and user friendly. Two months ago Woodwerks raised the price to $799. I had decided that it would be a good idea to purchase it before the price went up again. Then I found Amazon had the saw for $599 including delivery. I have purchased several machines from them: 15″ Jet Planer, 14″ Jet Lathe, 18″ Jet Bandsaw, Bosch Barrel jigsaw and others. All have arrived as promised without damage. So I have a high confidence factor with Amazon purchases.It was easy to spend this money on this saw.Others have criticized the weight, the noise, the inaccuracy, etc. I would like to comment on each of these points:WEIGHT: The Makita 2401 weighs in excess of 50#. It was one of the first Japanese Miterboxes to come to America. It has been virtually indestructable. The Bosch 12″ Saw weighs less. But because it is larger, there is a physical handling aspect that you should respect if you move it from site to site. It is certainly not as light as my Son’s DeWalt 12″ box. Don’t let negative reviews scare you.ACCURACY: I have never purchased any piece of equipment that didn’t require final adjustments. The factory settings are usually quite good out of the box. However, if you have to turn out superior work, each tool will require setup. Taking the time to go through the process provides you with knowledge of how to make the adjustments. It also allows you to understand when something is not right. Plan on spending 2 hours to make the needed adjustments to: 1. the miter detent plate and 2. the vertical scale. The manual is well written and relatively easy to understand. I used a 4″x4″ cherry piece to check/adjust the horizontal and vertical cuts. I found that by adjusting the vertical indicator arrow to the left side it is easier to achieve a more accurate and repeatable angle adjustment since the vertical angle is not detented.NOISE: The belt driven saws, like the Hitachi, are quieter since there is no gear clash. The Bosch is extremely quiet in comparison to the Makita 2401. I wear hearing protection when using machinery but this saw is much more ear-friendly than other saws I have used.CUTTING HEIGHT ON MOTOR SIDE: One review complained that the saw was limited to 4.5″ in height on the motor side. Anyone who has ever used the old Rockwell Sawbuck will remember the 7.5″ blade. Yet we were able to make wide cuts in trim materials simply by taking advantage of the long range of motion when the workpiece is laid horizontally on the cutting table. The purpose of any SCM saw is to allow these cuts to be made by taking the time to understand the way to set angles in the flat plane. Cheat sheets are available on the internet to show you how to utilize this powerful aspect of the tool. If you do not intend to use this function, then this saw is not for you and you would do well to buy a DeWalt 12″ miter saw.KICK FROM NON-SOFT START MOTOR: try an older saw like the Makita. You will quickly understand that this is nit-picking in the extreme.SAFETY SWITCHES: The saw has two safety switches on the top of the handle. You can cut from either side and find a easily located safety switch for either hand. Like any tool, there is a learning period. I know a man with 2 and half fingers missing who decided to defeat the safety switch on his miterbox. Learn to use it.TABLE NOT FLAT: this table is flat.UNPUBLISHED MEASUREMENTS: I mounted this saw on the left side of my workbench. I had to wait until I had the saw in my shop to get the measurements needed to set the height to match the workbench. There is no way I would ever take a written measurement as something to set a critical height. From unpacking to setting the saw’s mounting surface (bench) and setting the saw in place took less than an hour. The reviewer used this factor as a reason to “knock down” the rating. This is unreasonable and shows that the review is flawed and unreliable at best.DUST COLLECTION: There are few dust collection systems on any of the machines in my shop that would satisfy some of the ardent critics of this saw. Even the Festool at more than twice the price can’t do that.LASER – DIM: If you are novice, then the laser is important to you. If you are a craftsman, you rely on your eyes. I have not found a laser that can be as sharp as my old eyes.Conclusion: this saw is the best of the type under $1,400. Woodwerks’ repair department is full of DeWalt and Hitachi SCMs. The repair tech said that the Hitachi was the quietest and easiest to repair. The filled shelves speak volumes to me. Looking at the display models utilizing the two round tracks to support the sliding mechanism, I found side to side movement that was not present in the Bosch. I learned a lot about reading the various reviews, especially the writers who complained about things that are not really part of the machine. 90% favorable reviews to 10% disgruntled only proves you can’t make everyone happy. If you need this type of machine, buy this one.

    I’ve wanted one of these for a while now. I finally had an excuse with my latest project putting 6″ baseboards in the house, my old saw could’t do 6″ in a single pass….Calibrating the detent table for a nice 90 degree cut was a little tricky. After a few tries and getting “close,” I found the best way was to have a second person help. One held the square firmly against the fence with both hands while the second gently put pressure on the miter table until it was turned snugly up against the square.Another small note, where the dust collector outlet sits isn’t the best. We all know those dust bags don’t work all that well, and the outlet is near your head while you saw. I can see it was kind of unavoidable. the moving arm that makes the saw so great means there’s not much room for the dust port to go straight back like it does on regular saws. I used the lathe to make a a tapered hose adapter out of some scrap pvc pipe. I don’t plan on using the saw too much without the shop vac attached

    I was very hesitant to order the Bosch chop saw. I presently have the Dewalt 12″ sliding saw. I have been using it on the job for over 8 years and its as good as the day I took it out of the box. I needed a chop saw for the shop and this Bosch with the linkage instead of the slides, really is a space saver. When I read all the reviews, there were so many that complained this was out, and that was out and no way to adjust. Many said its junk, it forget this saw.? That really made me nervous, but I went ahead and purchased it anyway because of the space saving feature. I got this saw about a week ago and I have to say its great. Obviously those people that wrote those bad reviews did not know much about machinery. Even if it is perfectly set up out of the box, you should take the time to go over each item and double check. This way you know its right on, and you can check for any loose bolts, and you learn and get acquainted with the saw. Yes, it was suppose to be all factory set out of the box, and it wasn’t, but there are setting for everything and the manual is very well written and easy to understand. I spent about an hour going through each item and adjust every possible setting and stop. Extremely easy to set up, most all adjustments use the same size Allen wrench (that comes with the saw and stays on board the saw in its secure spot) Its very smooth with no play in the linkage. Bottom line, I was very impressed with the saw and would highly recommend it, especially for the shop setting. For the job site, I’ll continue to use the Dewalt as the Bosch really is pretty heavy. 89 lbs. I think it was. You would need the rolling stand to take it on job sites, but for the shop, I welcome the extra weight as it cuts down on any vibrations. And if you will be doing finish work with this saw, you will need a good finish blade. The blade that comes with it is a good blade if you doing framing. And I cant say much about the dust collection and the bag it comes with, as I hooked mine up to the dust collector system right away

    I am a high end fine trim for guy for south Florida. Been wanting something without the double tubes for the slider. The double tubes still always have play with precision cuts. The arms on the Bosch are solid and cuts being very precise. Also being able to cut 7 1/4 inch trim base is a big plus. Also love the fact you can control all angles from the front. The bevel adjustment being in the front saves so much time. First time getting anything other then the top of the line makita saws. But this has by far done more then expected and is been out preformed all previous saws.

    This is the top of the line best axial compound miter saw you’ll ever need.The only saw you’ll ever buy.Zero lateral movement when fully extended….,that’s the most important feature of any tool.It’s solid, and accurate, at a good price.The price has come down since i bought mine, but i’d buy another one at any price because i love this saw.In my opinion, the 12” is the way to go but i’m sure the 10” will do.The 22” just give you maximum capacity so you can cut boards standing up or large bulky stock without having to finish the job with another saw or having to flip it over.If your cutting long boards, you don’t want to be flipping them around especially if you are cutting many pieces. If you are looking to buy a full featured miter saw, you’ve found it.You’ll want to put it in bed with you.You’ll dream about it, and wake up smiling.The axial glide system is so solid and accurate, and glides so smoothly that Bosch has to incorporate a tension screw because it needed to be slowed down. How great is that. The axial system are two hinges mounted opposing each other at 90 degrees that makes this saw what it is, and it can be placed against a wall to save bench and shop space, then pulls out to a cut massive board widths.Easy blade change as well.It can’t be beat.This saw is top shelf !!!
