Does its job
We ordered this for a commercial installation involving drilling into a concrete pad. It worked well and did what it was supposed to do

Trabajo
Es bueno funciona muy bien pero si es poco pesado y el cepillo donde absorbe el polvo es muy frágil se rompe muy fácil

Better than all the dust extraction devices out there
Cons: would be nicer if it were more compact.Pros: works great , large storage for dust, powerful.

Pretty good
Pretty decent peace of equipment. Sucks up the dust fairly well. Difficult to tell if its suctioning till you see it in the filter.

Dewalt vacuum attachment for Hammer drills
Dewalt makes some DI products especially the 60 V line is amazing but I have to say this contraption works very well and I was impressed. The problem is is they have their own ankle drill system that uses a 3/8 or a half inch anchor with a little tap to put the ankle set All in one shot the vacuum wouldn’t let it go deep enough and I couldn’t use it. I had to return it. So I would say it depends on the application if it’s real short bit, it’s probably not gonna work, but if medium fit probably in real long bits probably not.
