    Looking into dust shrouds for 4.5″ or 5″ angle grinders.

    It seems some are vendor specific, and some are generic/universal.

    The dust shroud for surface grinding is different from a shroud for cutting.

    So my questions are:

    (1) It seems many of these inhibit your visibility. While it may not be so critical for surface grinding, it’s important to see when you are cutting concrete blocks or cement boards in place. Who is the best in terms of visibility?

    (2) Has anyone made a dust shroud that can serve both grinding and cutting? In other words, may be a shroud that can be reconfigured for the task?

    (3) In general, is your experience is a Makita shroud perform the best for a Makita grinder, a DeWalt shroud better for the DeWalt grinder etc…or is a third party shroud like Dastool, CutBuddie worth considering?

    I’ve only got shrouds by Bosch specific for my Bosch disk grinders and my surface grinder so I can’t really help other than in regards to visibily for cutting where critical, use a guide of sorts to execute.

    I’d also think that experience via frequently doing cuts without a guide with a shroud on is also doable accurately, but likely for those who do such on a daily basis which is not me.

    Did you pick out your grinder yet, or is the dust shroud issue part of your decision algorithm?

    Pretty much decided on DeWalt if I am going corded with the grinder, and Milwaukee if cordless.

    Since I do more cutting then actual surface grinding, a cutting dust shroud needs to be part of the equation. As far as I know DeWalt has a grinding shroud but not a cutting shroud. Milwaukee and Bosch has both.

    The shrouds made the Milwaukee, Bosch, Makita etc…are mostly metal shrouds with no visibility.

    Third part “universal” shrouds they do have transparent shrouds, however, in reading reviews many of them complained that they don’t fit on brands they claim to fit.

    Also noticed some complained that in a cutting shroud, as soon as the cut line is longer than the length of the shroud, the dust extraction fails because the cutting blade throws more dust into the groove then spin around the shroud.

    I don’t see a cutting shroud on MK Diamond’s offering. I see a few surface grinding shrouds.

    We usually cut wet with a saw.

    Outdoors on a horizontal surface I would also do it wet.

    Inside on a vertical surface, like bathroom tiles and cement boards, with an angle grinder wet cutting is not always that easy…unless I use a squirting bottle on one hand and the grinder on the other.

    If it’s a floor slab I will wet cut.

    If it’s on a vertical surface like 3/8″ porcelain tile over a 2″ thick mud bed with metal lath or concrete wall it’s easier to just use a grinder. Those are the use cases I want to use a cutting dust shroud. I have tried once with a squirt bottle in one hand and the grinder in another that doesn’t work too well.

    This thread is perfect timing for me. I’ll be cutting a vent for a range hood on the side of my house through brick. I’m thinking I should score it with an angle grinder and then chip with my cordless rotary hammer on chipping mode. The vent will be about 3”x11”.

    I have mostly Milwaukee corded grinders (four of them) so I ended up picking a Milwaukee branded vacuum shroud. But it is more for optimized for grinding, rather than cutting, and it is made of plastic, not metal, and it is black, not clear. And it isn’t quick release either. I’ve had it for 25 years, so I’m sure things are a lot different today.

    So in answer to your question #3, I went with the same brand shroud as the company who branded the tool, since the diameters would match. Not the diameters of the cutting or grinding wheels, but the diameters of the shroud collar that mates with the gear housing. I didn’t want any monkey business with the fitment. I wanted to pay the professionals (tool designers) for their already vetted and known to fit cleanly solution.

    Hence, I asked if you had selected your grinders of choice yet, because that might very well dictate either which dust control you go with, or which grinder you go with, due to the dust control.

    I like to us a saw on horizontal or vertical because I can attach a guide for the saw fence can ride on and tape on some plastic under so the slurry can be controlled.

    It all depends on the job I guess.

    I have one coming up soon that I need to make a few rectangular cuts in the ceiling.

    Old 1955 multiple ply rock lath ceiling. 3/4″ gypsum core backing, then another 3/4″ of brown coat plaster, then topped with a 1/8″ egg shell plaster, then may be 6-8 layers of paint over the years, wire mesh at all corners. A wet saw will be too heavy to hold upside down, slurry will rain on you.

    I would do a plastic tent for the one if you don’t want any dust to be in the house.

    I decided to give the Bosch GA50DC cutting dust shroud a try this week having to cut a recessed trench along a concrete wall and a bunch of angled cuts on old Chicago bricks.

    So here are the pros and cons:

    PROS:

    There is basically only one pro, it does cut down on the dust significantly, BUT it depends on how and what you are cutting. For example, if you are cutting a straight line along a wall, say 5′ long, the initially cut before still kicks up lots of dust, until the entire exposed part of the blade cuts fully into the material. Once it’s in I would say 70% of the dust gets collected. However, if you are making short cuts, like cutting at 45 degrees across a 4″X8″ brick, this shroud won’t help you much.

    CONS:

    (1) The dust shroud reduces visibility, makes it hard to see where you are cutting.
    (2) It’s a real pain attaching the dust shroud, and I am not sure if this shroud by Bosch is designed to work with multiple Bosch grinders, but my Bosch shroud does not have a very good fit on my Bosch grinder. Once the handle is tightened, the blade seems to have a slight skew, one side of the blade touches the guard. I had to finesse it to get it to clear.
    (3) The shroud does NOT mount two ways like the standard handle does on each side. It’s mounted one way and that way only. This makes it difficult to operate with the on/off button actually on the underside of the grinder if I am right handed.
    (4) The spanner wrench, when mounting the shroud, will only be able to turn a few degrees at a time when the shroud is in the way. You all know what a pain it is to have to depress the button to stay the locking wheel, this is much worse. See the picture.
    (5) The shroud really decreases the depth of cut. In some case with the shroud your cutting depth is greatly reduced. Try to cut across an inside corner, I had to remove the shroud to make the cut.

    Yes I didn’t have a Bosch hose adapter so I taped that connection LOL.

    Thanks for that mini review Sami.
