BoschHDC250 SDS-Max Hammer Dust Collection Attachment

This thing is awesome for keeping concrete dust down. I'm always drilling in finished areas, so this is a must for me.

This is meant for containing silica dust on a jobsite, but it does a fantastic job of containing the drywall dust from a regular old hole in regular old drywall. It's not going to send the chunks that might break off into the vacuum, but it will keep that fine gypsum power off of your clothes and bookshelves.I tip the top of this toward me when I remove it from a wall. That keeps the big stuff in the apparatus. Then I can either dump it or vacuum it out. I bought the big one so I would have plenty of room to use an oscillating tool for cutting in remodel boxes for electrical. I usually have to reposition it once or twice, but it works well.Another reviewer mentioned that there is room to stick a small LED light inside. That's a fantastic idea, and now I am day dreaming of hacking this with a permanent LED. Oh, projects: so many ideas, so little time to do them.

Works like a dream

Great for DIYers too. Sticks to vertical surfaces so well you could use this to hold a light load without damaging the wall. Works awesome so easy to use even if I am drilling a small hole in wood this makes cleanup so quick and as you drill you can see easier as the material is sucked away.

It requires a special vacuum adapter to connect easily to the hose. I used duct tape and that worked well. I use a 5hp Rigid vac with a dust deputy and HEPA filter and that easily held this to a brick wall while drilling. A little dust fell when we turned off the vacuum and took it down. I think having the correct hose fitting would be a good idea since shutting off the vac to remove it from the wall would not be required. It easily handled the dust while drilling a 4.5" hole.

Used this for coring holes in concrete for ductless ac units

Does exactly what it says. The more powerful the vacuum the better. The battery ones get the job done but you really want something with more oomph for more than one session. And it collects dust great but bigger chunks will clog the tiny port that goes from the wall suction chamber to the dust collection part. Just a detail. It truly reduced almost to cero the fugitive dust in confined environments when drilling concrete.

Esta pieza es buena porque no deja caer tanto polvo cuando se está barrenando con una barrena de 2 1/2

excelente producto cumple con su funcion perfectamente se adapta a las aspiradoras sin ningun problema

Why did I only just find out about this!? What a superb tool, I use it with my Henry hoover which goes straight into the dust extractor, and the suction to the wall is superb. I’ve done a few 125mm core holes and the dust is minimal. Really good but, I will be getting the smaller one next!

Perfect dust collection for larger sized concrete core bits. Easy to connect and use. Make sure the surface you place it on is reasonably flat in order for the vacuum suction to keep it in place. It does work for overhead drilling as well, but won't be as convenient compared to the normal horizontal and downwards positions. This is not a shortcoming of the accessory, but rather the weight of the rotary hammer and trying to keep it in a vertical position.The included adapter will fit standard shop-vac type hoses. If you are connecting a hose with non-standard ends, then this may present a problem. The easy fix might be some duct tape, but it's better to source the right fitting. There are available various inexpensive shop-vac reducing adapters for attaching to smaller diameter hoses.This dust shroud is well made. The flexible rubber seal is of good quality, and can be replaced if damaged. The body isof rigid, glass-filled nylon.

Fonctionne tres bien . Bonne aspiration qui le tient en place.

Anyone who drills holes through walls should have this product.it is well made and looks robust enough to last. Using it for the first time was simple,as it fits most vacuum nozzle ends.used it with my Fein perfectly.I think it's more suited to diamond coring than traditional coring bits.But it would work well with both.It left myself,my glasses and my work area very clean.It also looks very professional when viewed by customers.If you are the type of person who has gone to the expense of buying diamond core bits then I can't recommend this highly enough.I bought mine for around £30 but I have seen an alternative UK coded one for around £90.
