I picked up a Panasonic 24V EY6812 a few years ago and finally used it on a route this last winter. The body is 4 pounds 10 ounces and the Nickel Metal Hydride battery is 3 pounds 3 ounce. Came with two batteries.
I have not used other drills enough or recently enough to compare, but Barry Chambers was impressed. We were drilling 3/8" diameter by 2" deep in about 10 seconds each. I think we put in 10 or 12 holes in a couple of pitches and belays. There was no sign of slowing at all. That was in Tollhouse granite which might not be the hardest granite around but not soft either.
Don't know if they are still available.

C'omon Bachar, do some real damage.
Below; the one on the left for cutting down obstructions at the base, & right for touching up holds. It's the year 2007. Get the latest good gear.

Anyone with a Bosch Litheon or a Hilti TE-7a ought to be run off given they both have a hammer-only setting and available SDS chisels. I'd have to wonder about a person's intentions buying either.

... Gotta get me a new drill for the lead. What's the word on the street, Hilti or Bosch?
I used to drill with a Bosch 'Bulldog' but traded up for a Hilti - a little heavier but much faster. That was ten years ago - I imagine both companies have improved their products a lot since then. Which one is better now days? Especially for leading?
Thanks, jb...
Jesus, it's the end of the world as we know it.

Just got off the phone with Hilti, none of there new drills are lighter than the new Bosch and they are all double the price $1000+ compaired to $550
Per the Hilti website, the new version of the TE-6A with the lithium battery weighs 8.4 lbs.
Per Bosch, new 36V Bosch weighs 9.6 lbs. Older 24V Annihilator weighs 9.3 lbs (much less with the 1.7aH batteries that aren't available anymore).
Gotta get me one of them new lithium batteries...
End of the world? Nah, time to drill one handed is all...

Also, Werner, with the one on the right you may not need bolts because you could quickly slice a TCU placement into the rock. Then there's nothing to age, nothing to break and nothing to see, either.

Curt - don't worry, the world will not end. Brian in SLC has it - time to drill one handed (like placing a cam with one hand). I've done a few 12a steep face routes without resorting to hooks by drilling one handed - it kind of puts a new twist in the ground up game. Dan Osman was into it as well - even on a new route where he already had hung on a hook to place a bolt, if he got to a spot where he could drill one handed, he would! Crazy, eh?
It's a weird choice - I never wanted to hang on hooks and I also didn't want to rely on "electricity" either. Like I said up thread, I wish there was a way to hand drill with one hand/arm while hanging on the rock (like placing a permanent piton or somethng).
Don't worry, I'll let Werner experiment with all those power toys of the "future" that he posted!
Loomis - I like your rig - looks just like what I need

My buddy and I have Hilti TE 6-A that we got off eBay and we are wondering if anyone knows what we can expect performance wise. Specifically, how many holes we can drill in granite off one charge. I believe this was used for consruction purposes but it seems to be in good shape. I am sure its the original battery though. And what is up with the charger? Light has been blinking. Does this mean its charged? Thanks dudes!

Bachar I've got an old bosch bulldog that the battery is going south on. It would be ideal for conversion. Let me know if your interested.

Thanks, but I ended up getting a Bosch Litheon 36v. Works great, very fast but a little heavy on the lead. I got to figure something out for those tough placements - it's kind of daunting to drill on harder stances with this puppy.
Raydog -
you still make protective drill cases? anybody?

John: Bosch makes a big one (36V 1″ SDS-PlusŪ Rotary Hammer
Model 11536VSR) and a small 36V (18636)
They say the small one is comparable to an 18v regular Nicad hammer drill.
Could you share what you chose, where you got it, and what it cost you?
Also, love to hear how many holes you are getting per charge when you finish your first project.

Another option to reduce weight is to get 80-100 feet of speaker wire, sheath it in tubular webbing and leave the batteries in the ground. Then one can really beef up the battery system with gelpacks in series.

I've been really happy with both my Hiltis (but I've had older ones- not that wierd charger thing Werner spoke of).
I currently have a TE10A, but think that would be way to heavy for lead bolting.?
I think Hilti is a better drill, but $1,000 vs. $550??? tough call
Loomis- that rig is somethin else-nice job

Erik, don't see the TE-10 listed anywhere.
BUT, of major signifigance to all of us is this number: speed of drilling into concrete.
Hilti claims 450mm a min with an 8mm drill bit into B35 concrete with the TE-6a lithium ion.
Dudes, thats a whopping 17+ inches a min. I have drilled with the Hilti TE-6 and think thats most likely an accurate range. (8mm corresponds roughly to inch 5/16. So slower for the 10mm - 3/8 dia holes we commonly put in.
http://www.hilti.com/holcom/modules/prcat/prca_product.jsp?OID=13121&CATE_OID=-15380
The Big Bosch claims " Drills faster than key competitors, both corded and cordless! 50% Faster Drilling - 7.1 in/minute!", but doesn't specify the bit size and concrete spec.
http://www.boschtools.com/tools/tools-detail.htm?H=175982&G=54915&I=69863
If it's apples to apples, Hilti has a big performance benefit. If the Bosch is rated drilling a 1/2" diameter hole, well, not comparable then.
I have emailed them requesting this info and will post their response here.

I guess the blinking light means its fully charged. Hope so, because its one hellacious approach. Going to drill til the battery dies then its back to old reliable, "tink, tink, tink". I did grab a belt kit for the 36 volt Ni-Cad battery at the Hilti shop. I can throw the battery in a pack and go for it. Was a little worried drilling with that big dog all in one piece. Thing must weigh 10-15 pounds!
