          I'm looking to cut off a concrete landing/step at the bottom of my deck. I have a Bosch 5 in. General Purpose Diamond Circular Saw Blade for Cutting Concrete, Block, Brick, and Stone. will this fit on this Angle Grinder?
          ByJun 9, 2022
          1 Answer | 
          Answer This Question

          This angle grinder is not designed for cutting wheels and using it with a 5-inch diamond blade intended for a circular saw is not recommended. The provided guard is designed for Type 27 grinding wheels (4-1/2 inches) and may not offer adequate protection against debris generated during cutting. A different tool, like a circular saw designed for concrete cutting, would be more appropriate for your project.

          Can someone from Bosch recommend a type 1 guard to fit the GWS8-45 grinder? I kind of regret buying this model because I want to do cutting with it. Kind of sucks that all Bosch angle grinder are not made to use with an OEM type 1 wheel guard.

          Answer This Question

          Hi there! The GWS8-45 Angle Grinder is not designed for Type 1 abrasive wheel and the only guard you can use is 1600A00XU6. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

            Can this be used for cutting with a cutting wheel or does it require the purchase of another guard type just to do cutting?
            ByJan 26, 2022
            1 Answer | 
            Answer This Question

            Hi there! This GWS8-45 Angle Grinder is not recommended for use of cutting wheels (e.g. Type 41/1A or Type 42/27A). The provided guard is intended for Type 27 grinding wheels only and may not contain or deflect swarf, particles or fragments during cutting process. Other guard design or size was not tested, it may provide different result. For further assistance, contact us at 1-877-BOSCH99 (1-877-267-2499) from Mon-Fri 7A-7P CST.

              Does this require the purchase of another guard piece just to do cutting with a cutting wheel? It won't do cutting straight out of the box with a cutting wheel? I thought all angle grinders do both grinding and cutting with different wheel pieces.

                This was more than enough power to tile my fireplace at a reasonable cost.

                Powerful and light
                This angle grinder is both lightweight and powerful, and the cord doesn’t hinder me at all. It was also easy switching out the blade. Bosch always seems to be reliable brand.

                    Not rated for cutting and no guard available to allow for cutting. Although it can be used, lots of videos of people cutting with no guards at all, I’m not happy with the restriction so returned it and purchased a Makita which has an appropriate guard

                    Light weight and plenty of power
                    Only used this grinder a couple of times but I am impressed. It is light weight and has plenty of power. I would definitely recommend this.

                    Very good design. Easy to grip. Slide switch on the side is easier to access than my last grinder that had the top switch.
