drilling in concrete roof without dust

[electricalchief]

i have to drill about 2000 holes in a site that is in use. So i want a (new) driil with dust collector. i dont want a cheap collextro or a collector with external vacuum. so i m searching about this at first on internet.
I have found these bosch tools in good price but i want any info of already users, if there are.

bosch gbh 2-23
and

gsb 19-2


what do you think about?
any other suggestion?


cordless tool is a good idea but also is a too expensive choise.

forget cordless on 2000 holes. you'll spend more time waiting for batteries to charge than you will actually drilling.

Not used a Bosch one , but we use the hilti Te6 at work and they have cordless vacs , there pretty good to be fair !

I'd agree with that

i have a bosch gbh drill, its a really good piece of kit. theres offers for around £200 for set with dust collector, deffo worth the money.

Thanks for reply. my guestion is concentrated about the mix of a drill and dust collector. no just a the drill. I have already, bosch, makita and dewalt pneymatic drill tools.

Dust collector....isn't that what the mates for? Uh oh, I've had young Billy following my around with his pockets open for months now.
