The Bosch GWS8-45 4-1/2 In. Angle Grinder is a light, ergonomic grinder, with a slender grip circumference that allows users to work comfortably for extended periods. This 4.2 Lbs. tool delivers plenty of power, with a 7.5 Amp motor that produces 11,000 no-load RPM. It has directed air flow that diverts dust away from vital components. Bosch’s Service Minder brush system shuts off the tool when preventative maintenance is required, which helps to eliminate guesswork. This grinder has a two-position side handle. It has a burst-protection quick adjustable guard designed for user protection, as well as a large spindle lock for easy disc changes.

    This thing is like hand of God and will do all that you ask. Grinding and cutting like a champ. Throw a diamond cutter on here and cut through cast iron like a hot knife through butter! (Mine says made in Germany, not sure if that’s still the case)

  2. Wall2Wall

    This thing is a powerhorse. It will cut thru granite and everything else smooth and easy.

    We used it to cut tiles and it was very precise. Took some getting used to hit the safety trigger and hold it down to make it run.

    I previously wrote the following:
    “Just bought this grinder and bought a BOSCH disk (4 1/2 inch, DB4543S). When tightened, the lock nut makes contact with the backing flange, not the disk. The disk spins freely. What am I missing? I have tried flipping the lock nut over (made the problem worse). Should I have a washer? I cannot recommend this product just yet but am hopeful if this issue is cleared up.”
    I went back to the store of purchase and their staff graciously allowed me to swap my locking nut for one they had in a box for the same model. The locking nuts were obviously different but all other items in the accessory bag appeared to be the same. So issue seems to be with quality control (wrong accessory bag or wrong item in the accessory bag). I was told that the store would return the unit with the incorrect locking nut to the manufacturer tagged as defective.

    I have been using this grinder for a month so far so good. It is not the Bosch grinder I use at work by any means but I did not expect it to be either. This one has a smaller motor and a much smaller price so is what I expected. I just hope it will last a while on weekend warrior type fabrication. Mine does not seem abnormally loud and my switch works well.

    Bought this as a backup to my 1380 slim since bosch decided to take away a good grinder. Switch on this grinder now is junk, doesn’t stay on when I use it, always shuts off when I’m trying to use it and it’s slower than the 1380 slim was. Disappointed. Waste of money.

  7. Scottydog

    I just bought this grinder, It’s brand new, I’m sure it will work fine, I’m not a very good welder so I am a good grinder, this will be the fifth one over the last 25 years, they get abused, ask me for a review after I use it for a while. DUH. looks pretty HEY.

  8. Edalica

    We are a Busy Custom Metal Fabrication Shop and have tried multiple products that burn out within a week or 2 in some cases. This grinder stands up to heavy industrial use and abuse. It also has less vibration than many of its kind and easier to hold.

  9. Merk

    [This review was collected as part of a promotion.] I just purchased the GWS8-45, and was actually a little worried due to it being so inexpensive. I was very wrong, and am extremely pleased with the purchase. It is a well made product, and I couldn’t expect any more, except maybe a storage case.

  10. Dman89

    I have the standard Bosch 4.5″ grinder, this slim one seems much louder. Although it seems to be good quality, I don’t think the slightly slimmer design makes it any better than the standard especially because it louder.

  11. BigLuther1*

    I bought this grinder 2 weeks ago to replace the last grinder that quit working. It is not as bulky making it easy to hold. It sounds smooth without a rattle sound. I would buy again.

  12. RichB

    First angle grinder for me. Used it over the past few weekends cutting some steel posts and it seemed to work just fine. From here on out it will be employed for some masonry repairs.

  13. Chris1982

    I would have hoped for a hole in the wrench. Keeping track of the wrench for a grinder is very important. A hole to put a zip tie or lanyard through would be helpful.

  14. Anonymous

    Heavy for the size and does not come with a case or a bag. Nice power and quality button and grip. Even though it is heavy it is balanced well in your hand.

  15. Sdiddy84

    I love how compact the handle is. I can comfortably hold it in my hand and the weight distribution is perfect. I expect nothing less from Bosch.
