Bosch GWS8-45 4-1/2 In. Angle Grinder

I bought this grinder to use with poly abrasive stripping discs to remove paint on an older ranch house. I appreciate that the grinder is not heavy while still being beefy. The grip is small enough to run one handed, which I needed to do often while stretching arms length at the top of a ladder. The left-side push switch took some getting used to when using left handed. The constant on function works easily...push the switch forward and then press inward. I ran this grinder continuous for up to 15 minutes at a time, through a 5 pack of abrasive discs, over three days, grinding off old paint on wood siding. The grinder got warm, but never overheated. I was impressed. I like the safety guard. It fit the 4 1/2" x 7/8" poly discs perfectly with no contact. The guard requires an Allen key to loosen and reposition it. A clamping guard would be a plus. The auxilliary handle can be used on either left or right. One thing I. like is that the Allen key for the guard, and the wrench for the blade nut are all in one piece, an interesting tool, a little different from the standard wrench. The holes in the blade nut are standard width. It took me about one minute to assemble the tool out of the box. The single speed is rated 11,000 rpms, and I note it runs constant, and has not bogged down in my use. The wheel-lock on the back is red, and is easy to use while changing a blade. Glad I bought it. This is an excellent quality tool for professionals that definitely goes to the job site.

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.

Very sturdy and lots of power . Very good price !

I have several hundred hours of work done with one of these on a huge project, so I bought another one just in case. I highly recommend this Bosch. It may not be the most fancy looking one on the market but it is a workhorse. The construction is durable and i was able to buy some accessories for it, like a vacuum collection cover that just made it all that much nicer to use. It's not any louder than the DeWalt angle grinder, but the side switch on this one is a little bit harder to activate. Overall pretty happy with it given the price and the durability.

Now, disclaimer, I'm fairly novice with grinders. I bought this for the welding class I'm in, in which I grind lots of metal all day everyday. It's pretty resilient, fairly powerful, and still smaller than others which to me is great. I do have some complaints though, some may be more specific to my situation than others, I'm not sure. The tool itself while small can still be awkward to hold, especially if what your grinding is higher up than hips/waist height, the placement of the handle going more forwards also adds to this problem. Another issue is how the safety guard attaches/adjusts, it goes on the very back layer and you have to position it properly in one of the set places, then screw it tight to keep it there, meaning if you frequently want/need to adjust, it's pretty tedious. Overall it's plenty great for my purposes, just some minor things to consider and how it will impact your usage

I needed an angle grinder to use with my new lawn mower blade sharpener. Can't say this is any better than other name brands but the price was attractive and it seems like a quality tool. Been working well for me so far.

THIS FIGHTS ABOVE IT'S WEIGHT. SURPRISED ME HOW STRONG IT IS. I'M SHARPENING TRACTOR BLADES.

Was the best choice for me out of the dozens of models for sale. Good ergonomics and powerful. I have had good luck with Bosch power tools.

Exelente producto!, como siempre Bosch no decepciona. Trae un disco de desbaste para que consideren las compras que realicen. La relacion calidad-precio es muy buena, tenia mis dudas sobre la amoladora pero entrega buenos resultados. Ya ranure en la pared, corte tubo de acero y realice trabajos de lijado con disco de grano 36, todo sin ningun problema!!!!

L'outil Bosch utilisé pour couper un trou d'évier dans une tuile de céramique porcelaine de 24 po. X 48 po.. Facile à utiliser, precis et n'effrite pas la tuile taillée . Facile à soutenir et manier avec une main. Je recommande fortement. Vous ne serez pas déçu.

bon rapport qualité /prix

Se ve de buena calidad y con buena potencia.

La marca la precede! Es buena herramienta!!
