HERZO Dust Shroud Dust Extraction Cutting Guard for 5 inch and 4-1/2 inch Angle Grinder

This worked well with my Ryobi Angle Grinder. * Just make sure you adjust the small notched guide to align with your blade. Dust was minimal. Price is good for the project I used it on. It will hold up to several uses if I need to use again.

This item is constructed well. I had previously bought a different style and the depth adjustment broke the first time I used it because it was just a piece of flexible plastic. This model has metal threaded knobs for the adjustable portions which are much more durable. Visibility is really good and the included vacuum adapter allows it to adapt to lots of hoses. The dust port on the inside includes a cross-brace that catches larger pieces from making it back to your vacuum, this can get plugged with larger pieces but wouldn't be hard to remove. I'd buy this same unit again.

Seems to be a well designed product except near impossible to see where you are cutting. Its clear plastic but you can't see the blade where it contacts the concrete. It does have a pointer at the front of the shroud but impossible to chase concrete cracks. Would work fine if cutting a straight line. It did fit my Makita 5" battery powered grinder and comes with a variety of adapters. I ended up cutting the cracks with one hand on the grinder and the other hand on a shop vac hose directly behind the diamond blade. Worked well capturing most all the dust/chips. I did about 150ft of cracks in a couple of hours. Went down about .5" then filled the cracks with self leveling sealant. Sanded the filler a few days later. Good results

I think anyone using this shroud for making straight cuts in concrete will be satisfied. However, mine failed when attempting to use with a 3/8" crack chasing blade. The connecting collar was too fragile to stand up to twisting forces from cutting irregular shapes. The shroud was knocked out of alignment too easily, causing the blade to come into contact with the plastic housing.My workaround was discarding the shroud, and cutting with one hand while vacuuming with the other.

A friend of mine who is into Granite counter tops was going to do me a favor and remove one section of the counter so that the cabinet could be changed. The plan was to cut an existing joint so that the piece would be manageable to lift.Long story short is that I had bought this HERZO cover unit for another job but when I tried to attach it to my Bosch angle grinder it would not go down far enough. The friend who came had another brand and it fit on his just fine. I connected it to my Dewalt 9 gallon shop Vac and he made a perfect dust free cut. I really like how he could set the blade height just right and also keep the angle grinder level using the flat area on the Herzo.That dust free experience and perfect cut was worth the money I paid for this.

I tried this on a DeWalt angle grinder and a Milwaukee...two of the top brands and it doesn't fit either. I bought another grinder (Bauer) that looked like it should fit and it barely fits. Looks like I can make it work in one orientation only...not very user friendly and after reading the negative reviews I'm doubting this will even keep the dust down!

The media could not be loaded. I found very few grinder dust shrouds for cutting. I came across this one and thought I would take a chance. I almost returned it before trying it because of my skepticism. I'm glad I tried it because it worked amazingly well as you can see.

Shroud seems to be well designed and includes a number of ring and vacuum hose adaptors such that it accommodates my Bosch 1703evs 4.5" angle grinder and vacuum hoses without difficulty. While the shroud is not the quality of a Bosch accessory, it seems just fine and should withstand for years the limited use that I intend it for. I like that the kit included a diamond blade. I recommend this product for general use. If I were using it on a daily basis as a professional, I would have purchased the Bosch unit.
