    • Read the manual! But, yes, it can cut.
Style: Adjustable
I bought this to cut some ~1/8" steel. In particular, this rack: https://www.amazon.com/dp/B002RYYY7C?psc=1&ref=ppx_yo2ov_dt_b_product_details The two rows of holes on each post are in line with each other so the rear set needs to be cut off. Not knowing that before I bought that rack, I bought this grinder to do the cutting. I was shocked to find that the manual claims that this grinder cannot be used for cut-off applications, because it doesn't say that anywhere on the Amazon page, or even on Bosch's website, unless you download the manual. However, other manufacturers such as Makita offer similar-sized grinders with the same or lesser specs that claim to support cut-off work, so I figured why not give it a shot. And sure enough, it works just fine. Just don't lay into it too hard and let the disc do the work. Also, wear adequate PPE and a dust mask or respirator, it generates tons of particles and stinks as the disc wears. Other 4.5" Bosch grinders claim to support cut-off applications, but it seems that Bosch has discontinued the "optional" cut-off guard, and finding guards for other brands of 4.5" grinders seemed equally challenging at this price point. It would appear that most people just toss a cut off disc in there and go, using the included "Type 27" guard that comes stock with this and any other brand of entry-level grinder. User beware, and be careful, but there are loads of videos on YouTube showing people using grinders to cut metal with Type 27 guards installed. Installing a Type 1 (flat) disc doesn't leave a lot of clearance with the included guard though, so I opted for a Type 27 cutoff wheel. This has the depressed center like the included grinding wheel, and offers better clearance. The one I got (Norton Blue Fire) says to use it with Type 27 guards, which happens to be what's included with this grinder. Despite this, the manual says not to use the included Type 27 guard for cut-off applications. It appears that there's a lot of conflicting information as to what can and can't be done. Or rather, what should or shouldn't be done. But for everyone wondering if this grinder is suitable for cutting, the answer is yes. Buy it, you'll be happy. It's inexpensive, and if you burn it out, just buy another. It'll still be less expensive than some of the other higher-end models out there. You'll be happy. ... show more

    • DON'T FORGET INNER FLANGE IS THREADED!
I. Am. An. Idiot. I started an earlier review talking about how I'm a professional furniture maker (bona fides/credibility, right?) who has owned many grinders over the years and while I love this grinder, I couldn't get the inner flange off... either because the machining tolerances were too tight, or there was some burr, or it just otherwise decided to fuse itself on. I even tried to use a gear puller to get it off!!! I had my return all set and figured I'd just get a replacement and make sure I reamed out the flange before seating it. Then I had a horrible thought... and searched "flange" among the other reviews. (Major face palm). Yes. This Bosch grinder is different from all the other grinders I've owned in that the inner flange is also threaded... and, I totally forgot that. What a dummy. Now I feel so bad for all the abuse I subjected this beautiful little machine to. Here's the highlights from my previous review: I like having at least 3-4 grinders set up at all times with different discs so I never have to switch mid-job. My wrists have started to get pretty sore by the end of the day, so I wanted to find the lightest grinder possible -esp. for careful detail work. My go-to grinders have always been Makitas but I thought this Bosch was worth a try. Immediately, I was impressed with the design and quality. The machining and finish of all the parts looked great and it felt great to use. Grinders seem like they should be the same -it's just a motor with a threaded shaft, but compared to a crappy Metabo I wasted money on, this Bosch ran like butter... so smooth, hardly any vibration... very well balanced and lightweight... seriously, a pleasure. I imagine eventually replacing all of my grinders with this model. Anyway... I heartily recommend this grinder, just don't forget about the threaded flange. And, the only other comment I'll make is -the cord is kinda wimpy... it's like the strength of a licorice rope... so, just make sure no off-cuts fall on it... that's all I'll say about that... otherwise... it's a great small grinder. ... show more

If you need to get into tight spaces for light to medium grinding or cut offs this tool is great.

    • Best to hold comfortably
Style: Adjustable
I checked out a lot of angle grinders from different manufacturers, my need being mostly DIY projects. I needed something that is fairly good quality, is good budget wise, should be easy to hold, not too heavy and easy to maneuver. Also it needed to be able to stay on without having to keep some paddle switch pressed continuously. So it came down to a choice between the Bosch 1735A (which seems shorter in length in the picture) and this one. This GWS8-45 is so slender that my thumb can almost touch my middle finger holding it so superb to hold and use it. I went with the GWS8-45 since it has the higher 7.5 amp rating though for my use even the 6 amp rating would be sufficient and the 1375A might be even more easier to hold and maneuver. Maybe I would have gone with that if I had both to hold and compare. The blade guard on the GWS8-45 is a bit interesting to install and not too easy to change positions. You have to use the provided key to loosen the bolt and then turn it around and tighten it. However the positive qualities more than make up for this and if you are using it set to a particular position for grinding or for cutting, you won't really notice it once set. ... show more
