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

Demo'd this shower stall in a 100 year old house. Used HERZO to cut the grout lines so that this would break up with a 4' bar. HERZO is an excellent add on that allows you to work without clouding up the whole project! Depth gauge works well. Overall design is excellent. The only complaint is that most people using this type of tool, have Shop Vacs that have a much larger hose than what the adapter accommodates. Nothing a couple laps of masking tape couldn't cure. BUT, we really should not have to do this. Great product otherwise and could not be happier!

Had to cut concrete inside the house. Used the attachment and it worked great. Fast delivery and decent price, came with extra blade. Highly recommend

Más piezas que las que pensé!!

Came with everything I needed was just as good quality.As the higher priced items

Overall a nice package.Pros:Clear material allowed guiding the cut. Fit my old Mastercraft angle grinder. I used the included inner flange pad.Captured most of the dust.The 'baseplate' would be useful on a flat surface.The baseplate can be used as a depth gauge. Nice feature.Came with a diamond blade. I haven't evaluated it because I already had one.Came with a nut wrench.Cons:Dust capture is spotty on irregular surfaces like a stone wall. I did notice that I could improve the dust capture by angling the grinder to 'nose down' into recesses between stones.My shop vac hose did not fit the dust port on the product. Luckily I had some rubber gasket sheet from which I cut a strip to fill the difference. This also held the vacuum hose to the dust port. Herzo would do well to address this for future units.Beware that you have tightened the unit well. If it works itself loose it will go towards the blade and damage itself. Unfortunately this relies on a pair of small Phillips screws. Make sure you have tightened them.Notes:Don't start grinding plastic away till you've checked all the components. On my grinder the unit sat right up against the blade until I tried it with the included inner flange.If it doesn't fit you may need to use one of the included spacing rings (clamping washers). I used one for my Mastercraft.
