Angle Grinder Dust Shroud and Grinding Wheel are heavy duty & make short work of tasks
We've had an angle grinder for probably 40 years but you know what I haven't used it very much until I got this diamond grinding cup wheel with the Dust Shroud. This grinding wheel makes the very short work of difficult tasks when you are grinding down a surface like part of a driveway or smoothing out some sharp concrete on a walkway, like my husband did. The grinding wheel is aggressive and works fast. I am searching for reasons to grind something because it is so effective and when you are able to smooth something out that has been on your radar for years, in a few moments, it is just cool. The grinding well industrial out were pretty simple and standard to assemble on our angle grinder. Now our angle grinder is probably 30 years old and it is a very heavy duty and I am this grinding wheel so much that when it wears out I'm going to get more because it out a chore in a few moments that otherwise with other tools would take hours. This feels very durable The grinding wheel edges are sharp and hard and work very well Period now it's not meant to last forever these are heavy duty chores but they do make short work of each chore and that is a fantastic value. Well worth the reasonable price point. If you need a very aggressive grinding wheel for your underutilized angle grinder This one is pretty good and works well It's easy to assemble and pretty self explanatory

Well made - won't fit Bosch GWX10-45DE
Last year I bought a Bosch GWX10-45DE 4-1/2 In. X-LOCK Angle Grinder to do some leveling on some of our walkways. I knew I would need a dust shroud; but after doing extended searches I found out that Bosch does not make one for this model. I've tried a couple of 'Universal' models; and no luck. I saw a post that said someone had made a universal model work by removing the shroud adjustment lock before installing it. I've been looing for a universal dust shroud for 4.5-5 inch angle grinders that look like they could work for my Bosch since seeing that. So, I was very interested in trying this FectoSaw Dust Shroud when it appeared in the things I could try from the Amazon Vine program. I was impressed with it when I opened the box. There is an adjustable mounting system to fit types of angle grinders in the 4.5-5 inch size range. It come with 4 sizes of collar rings, a universal wrench, and 2 vac connection adapters, plus a 5 in grinding disk. My model is a 4 1/2 in; so I knew I wouldn't be trying it for safety reasons. I took off the lever on my grinder, and tried to fit the basic collar onto my grinder. It won't fit; but the Bosch GW series seems to be unique, so I don't blame FectoSaw for that. I can see this being a great addition for a wide range of 'normal' grinders; so only minus 1-Star for non-universal with my Bosch.

Not "universal", probably works fine if it fits your particular grinder
Unfortunately, despite the claim of being "universal" in several places, it won't necessarily fit your angle grinder. It doesn't fit mine, a Chicago Electric from the harbor store that sells freight. The opening diameter is fine and one of the included adapters would work, but there's just not enough clearance for the shroud to sit flush on the grinder gearbox. It does seem well made and I'm sure it would work fine if it fit my grinder. The shroud is plastic though, so it might not hold up under daily use. But then again if you used something like this on a daily basis you'd probably have a dedicated concrete grinder rather than repurposing an angle grinder. For homeowner or DIY purposes, I think it's probably fine. There's probably no way you're going to know whether it fits on yours or not unless you try it yourself. There's no way I would have been able to determine from the pictures or description that it wouldn't fit on mine.

Awesome product. Safety is very important when grinding masonry
I’m super happy to have this dust collector attachment for my grinders. I don’t grind masonry often, but when I do it’s for extended periods. Grinding stone makes a huge mess, and requires strict PPE, so it’s great to have this dust shroud to contain some of the debris and dust. The adapter is sturdy plastic, and it comes with adapter rings to fit it to different size grinder housings. It’s easy to attach, and stays secure once it’s clamped down. While it claims universal fit, it is still heavily dependent on individual grinder designs, because there are so many types. Unfortunately, this adapter would not attach to my DeWalt DCG410 right away, and I would have to unscrew the spring finger for DeWalt’s quick guard adjustment system to let it fit. I didn’t want to mess with taking small parts off of my grinder, so luckily this fit without problem on my Craftsman CMCG400. The biggest criteria to make sure it fits is to ensure the grinder has an unobstructed and smooth spindle housing. The set includes four shims of different thicknesses, so the most critical part is ensuring nothing is sticking out of the spindle housing that would prevent the ring from sliding onto it. As a small nitpick, I suggest the manufacturer proofread their safety label, and perhaps fix it so it looks more professional. While it’s good that they cared enough to put a safely label on the dust shroud, and I appreciate that they did, the warning should be formatted properly and not have typos. I attached a picture of the label to show the typos and forgotten spaces between words. It comes off as sloppy on an otherwise well thought out and manufactured product. Overall, It’s quite good value when you consider that it comes with a grinding disc, and I’m happy to have it. Just visually inspect your grinder to ensure it will fit unobstructed before purchasing, and I don’t think you’ll be disappointed.

Excellent dust shroud and grinding wheel.
Pleased to report that this worked perfectly with my grinder. Used it to level out the high spots in our kitchen during renovations. Dust shroud and grinding wheel worked beautifully - ended up spraying the concrete to keep dust down for good measure. Overall excellent. The spacers were invaluable, was able to fit one to my grinder for a perfect fit.

Works great!
This dust shroud and grinding cup combo works very well for concrete and similar surfaces. It fits a typical four and a half to five inch grinder securely once the height is adjusted and the brush ring sits flat on the floor. The included diamond cup cuts concrete smoothly and removes coatings quickly without bouncing all over the place. The vacuum port is a good size and once connected to a shop vacuum the amount of dust in the air drops a lot, which makes a big difference in a garage or basement. The clear front section makes it easier to see the edge while grinding and the spring door lets you get close to walls. It takes a few minutes to set up correctly the first time but after that it goes on and off quickly. For the price it is a very useful kit for smoothing concrete, prepping floors, or cleaning up rough patches with much less mess.

Measure your grinder for fitment before ordering
FectoSaw Dust Shroud for Angle Grinder, 4.5-5 inch Make sure you measure your grinder before ordering since this only fits grinders with a maximum diameter of 48mm for the mounting collar. My grinder was 57mm so I could not mount this and give it a try. It comes with different collars to fit different sized grinders, a couple of adapters for different sized vacuum hoses, a wrench and concrete grinding stone. The shroud is made of plastic but it seems durable. I don't think this would be good fit or hold up under daily use but would be a good fit for occasional DIY use. The front can open up so you can grind right up to the edge of walls. The price is reasonable given the materials and quality. I would recommend this only if you have a small job here or there that would require it.
