The grinder is smooth running and the soft start-up is a pleasant feature. The speed dial offers a large range and is located at the back of the tool where it is not likely to get bumped. The guard is easily attached and removed. It is nicely balanced, even with the additional weight.

You'll appreciate the soft start especially when working at high grind speeds. That alone would justify the additional cost of this vs. a standard grinder.

Blade cover was easy to remove and attach. One of these days I may actually use it.

Quality, long power cord with long lasting strain relief. (You know the tool will eventually be carried by the cord.)

It has excellent torque for a small motor. Difficult to bog down unless I'm using a large diamond disc.

I have abused and misused this grinder to the point I thought I'd kill it. I blow it out and it works as good as new. It has held up to regular all day long use.

I have never been disappointed with a Bosh tool. This is no exception.

Let me just say that I was urged to buy a variable speed grinder by my dad who has owned his (and probably a few others) fair share of tools and let me tell you he was right and I urge you to GET A VARIABLE SPEED GRINDER.

After reading some reviews on other resources than here it looked like some bosch grinders really had great balance and let me tell you I was definitely not disappointed.

Besides what others have said about the variable speed, and the slow startup (both very nice features btw) I would like to add some other comments however. The balance on this grinder is absolutely amazing. Everything feels so smooth I've even one handed some things and felt totally comfortable doing so (of course, I wouldn't recommend for others to do the same as it isn't the safest).

I have used this tool on a range of mediums, from sanding down some wood edges with the grit wheels, to taking down a fiberglass sub box I've been creating, to cutting off some loose screws hanging from the studs in my garage. Through all the tools has felt wonderfully balanced and incredibly receptive to whatever you toss at it.

2 things no one else has mentioned yet is that the cord is made out of the higher quality rubber/plastic and is the type where when it is in extreme cold temperatures it stays malleable and flexible. This is a relief to some other corded tools that stiffen up horribly in the cold.

Also, I will say the only downside i have to this tool is that the trigger is extremely difficult to press forward and hold forward, so I nearly ALWAYS find myself locking the grinder on.

I am stripping paint off concrete floors with a Norton Non-Woven Depressed Center Rapid Strip Discs, 4-1/2" Diameter, 5/8"-11 Arbor Hub, Grit Coarse (Pack of 1). I bought a 13-amp DEWALT D28115 Heavy-Duty 4-1/2-Inch/5-Inch High Performance Grinder with Trigger Grip and it works great, but Dewalt doesn't make a dust guard and I couldn't get the Bosch 18SG-5E 5-Inch Surface Grinding Guard to fit. This grinder was highly rated so I bought it.

Unfortunately it bogs down constantly when I use it and is essentially worthless for any heavy duty grinding tasks. It might be great if you need a light-duty variable speed grinder but otherwise it's a waste of money; might as well just buy a cordless. Bosch doesn't seem to make any 5" grinders over 10 amps.

Also I found the switch to be inconveniently located and annoying to use.

i give this variable speed angle grinder 5 stars based on its price and the fact it performs very well. It costs considerably less than other name brand angle grinders yet works very well. I have used this to polish granite with dry pads and it works beyond my expectations.

Good machine, angle grinders should all be variable speed control due to the variable speeds required in different materials.
I am somewhat dissatisfied with the low torque especially noticeable at low speeds.,but this is to be expected in all but the most expensive variable speed grinders.

By Tim Merkin on November 16, 2011
I am abusing this angle grinder by using it to polish an entire concrete floor ( about 14 x 14 foot room ). I first started out with a dewalt 7" grinder and it about rattled my teeth out. I returned the Dewalt and bought the Bosch 1803EVS and immediately noticed a huge difference due to the vibration dampening handles. The Bosch 1803EVS also had sufficient power to spin the 7" diamond cup wheel just fine even though it is labeled as a 5" grinder. The variable speed option was huge The Bosch was a beast and allowed me to chew through the very hard concrete surface to expose the aggregate. I have since used it for every polishing stage after the cup wheel (50, 100, 200, several 400, several 800, and 1500). I have polished both wet and dry with it. The thing is a beast and runs like a champ. I easily have 80 hours of very abusive solid grinding and have had no issues. I also bought an additional vibration handle (one for each side) so that I can use both hands to push evenly down on the floor.
