I'm about to route some new RG6/cat5e/speaker cable through my finished house. I'll have to drill through wall studs and will need a right angle drill.

Anyone have a recommendation? I definitely want a corded drill as I hate having to wait for a charge. How many amps will I need to punch 1" holes through studs/joists? Thanks!

If you're only going to be using it for this one job you might consider renting one. Also, when I did some of this for running electrical and needed to do about 20 studs I just used a spade bit and my normal power drill. In my case the walls were open and the overall length was short enough to fit in the stud bay so I was able to drill straight through w/o any problems.

You don't need a right angle, use any old drill. The holes don't have to be straight, they could be on a little bit of an angle of your drill won't fit into the stud bay.

I do very little residential work, but when I do, I use a spade bit with my 18v Dewalt. It cuts thru like butter and 2 batteries last me all day.

If you are only going to do a few of these you might want to think about a right angle drill attachment:

I picked on up for $15 at a tent tool sale. but they are available on-line as well.

I've got a Hitachi I bought around 10 years ago and somehow the batteries still hold a great charge and it's got a ton of power for 9.6V.
I've also been known to chop a spade bit down in length with my bench grinder to buy myself more room when drilling in tight places, that might be all you need to do to be able to use your regular drill.

Mark F, funny you should mentioned that, I have an old 9.6V Makita right angle drill that still runs great, even the batteries are still going.

It's got a chuck key, it's not variable speed, it doesn't have a clutch to stop it from spinning when you let off the trigger- BUT it still does it's job!
