I use a cheap a$$ Black and Decker drill I bought for 60 bucks Canadian Brand New.....with standard Masonry bits....It's only 14.4Volts.....Runs out a little quicker than most but I just carry an extra battery......I have drilled sandstone, limestone and granite with it.......This crap about NEEDing a hammer drill is nonsense....yeah it works a little better but if your budget minded......and have a little extra time.....about 30 to 90 minutes more per route ....go with it......inn the end it is you who must balance the pro's and cons of each......

Bosch is the old reliable, get lots of bits and extra battery packs. You'll get tired of drillin' holes soon enuff.

In reply to: My Hilti Te-6a has gone as many as 45 holes 3/8 by 4" in good limestone, the thing is way more efficient and comfortable to use and the battery charger actually works, My annihillator was great but with the 3.0 ah battery I was only getting like 15 holes tops in good rock.
Something was wrong with your battery or charger or both. Friends of mine are getting similar performance if not better with their Annihilators. And you are leaving out the price of the TE-6A battery here, which is $300 as opposed to the Bosch, which I hear is more like $70. I still regret getting the Hilti for this reason.

Sorry, you are totally incorrect on this one 15 holes out of a 3.0 ah bosch annihilator is the norm around here, I know 4 others who own them, and yes the bosch charger is a weak unit.
the bosch runs on a 16 amp motor and has two 24 volt cells to run on for 3.0 ah.
The Hilti te-6a has a 12 amp motor drawing current from three cells at 36 volts, 2.4 ah, your argument makes no sense the hilti flat out kills any bosch drill, would'nt trade back for any reason, when i go out and haul 70 lbs of gear and jug endless rope the last thing i want is to run out of juice at a different bolt count everytime, the hilti will go home with power to spare everytime.

So the Bosch chargers are limiting the efficiency of the drill's battery you are saying? Well if that link in the chain is weak, yeah, not a good selection. None the less, a friend of mine has reported getting very impressive results when he first bought his Bosch Annihilator drill new. I hate to try and guess at the number of holes he was getting on each battery, since I don't recall the size bit, hole depth, etc. But it was over 50 I sort of recall in concrete. Not sure how it's doing now.
I've never put the Hilti to the endurance test with a stock battery.

Concrete!? Are you joking? That doesn't even compare to rock. What numbers is he getting in rock? Last Sunday my TE-6A made 32 holes (3/8x2 1/2) in granite with plenty of juice left and I've had better days than that. I don't know about the Bosch, but I know my drill smokes!

The only point I was making is that the Hilti te-6a draws less current from its battery and it has a 86 watt hour battery at 36 volts, so its power reserves over the Bosch annihilator are huge. the Bosch is a great drill but it drains its battery very quickly, and when bosch issued the 3.0ah battery to replace the 2.5ah battery they made no change to the charger, wich already was a piece of crap.
The bosch drill has no deep discharge prevention, the hilti simply shuts off when its time to recharge, and the hilti charger trickle charges and conditions the battery for best results.
Operator comfort was the biggest selling point to me, the rubberized ergonomic handle and lack of vibration transmited to your hands are great as well as not having to really ram it into your work to get it to drill, especially helpful when drilling on lead or in caves, My bosch required constant, strenuous pushing to engage the hammering mechanism, this kicks your ass when your holding a bolt to your waist and drilling way over your head. if price is your issue go on Ebay I found mine for 200. bucks brand new in a case, and was able to sell my Bosch for more than i paid for my Hilti, piece smky.

There's different grades of concrete just like different types of rock. No comparison between, say, entrada sandstone and the quartzite in the Uintas, for example.
I'd take drillin' in soft matrix in Maple over old, hardened concrete. And, no doubt some concrete is a bit harder to drill into than the granite at, say, Castle Rock.
TE-6A rocks. But, I'm leanin' toward the Bosch for further from the trail and lead stuff. So much more compact and lighter.
Mike, you probably got lucky and have a "tuesday" or "wednesday" model... (btw, how many routes?)
Just picked up an Annihilator. I'm curious to see how it works...

Why not just rent a Hilti for a weekend? Most equipment rental places carry hammer drills and it should only set you back $50 or so.... Go ahead and mark the spots where you think a bolt would be necessary while on toprope before renting one though...

I think the best thing about the TE-6A (as previously mentioned) is the deep-discharge prevention and the conditioning charge mode. Time will tell whether or not that equates to actual longer life of the battery, but it should. It certainly takes the guess work out of "maintaining" the battery. One thing I would change about it, is that there is nowhere good to tie a shoulder sling...you could duct tape it do the handle, but I hate gunking up a brand-new tool like that. The ergo-handle is pretty sweet.

Actually they weigh the same, unless you purchase your annihilator with the tiny 1.7 ah battery, in wich case good luck even getting one pitch up a day.
The Te-6 is actually smaller, I used to own both these models

4000 psi Concrete is fairly comparable to medium limestone, which is all I have bolted to date. Super hard limestone, eh, fewer. And you have just admitted that you don't know about the Bosch. I have used both and have the TE-6A myself. Really, is there a reason for all of this misplaced emtion about one's choice of drill? It's a tool for Christ's sake. Both are good.

No they don't weigh the same.
TE6A weighs 10.4 lbs, Bosch Annihilator weighs 9.2 lbs with the 3.0Ah battery, and 7.7 lbs with the 1.7Ah battery.
Above is according to the specs available on each products website. And...I have to say, that holding each one out in front and above you with one hand, even with the 3Ah battery, the Bosch feels much lighter.
Size wise, they seem about the same (should measure them side by each). The Bosch seems smaller to me, and the case is a BUNCH smaller.
Specs on length are 13.0" each. TE6A is 3.9" in width and 8.9" in height. Bosch website doesn't list a width and height.
One thing I wonder about, is overhead drilling one handed with each drill. Hilti is heavy and bulky, but, rock-n-rolls. Bosch has this clutch thing that engages under a load, so, I'm wondering how that would work while you're sweatin' bullets leading (anyone know?). Bunch of folk seem to like leading with them.
Balance of each drill is nice in that they aren't too long compared to the weight distribution and battery location. Be even nicer with a 4" drill bit (anyone know of any 3/8" diameter 4" bits available for these drills??).
Mike, I girth hitch a 6mm cord onto the handle of the TE-6A with a short loop to which I clip a locker. Then attach to a padded gear sling. Seems to work well, carry well, hand nicely, easy to pick up and put down. No tape mess either. Will probably try to fixture the Bosch the same way.
Just bought some lead acid batteries...will have to give them a try...in a fanny pack, makes drill body light to get the batteries off.

Post subject: Re: Advices to buy a drill for bolting
the plural of advice is advice not advices :shock: unless advices is some totally new word that I have never heard of and is not in websters which I just got through checking (I had a dictionary by my desk):)
just it would be nice to make another post that has no relevance to the origional question
:wink:

Obviously you have never seen "Pumping Iron" with Arnold:
"When it comes to the competition, I am his Father.
He comes to me for advices. So, it is not that hard to give him;
the wrong advices." -Arnold
Brian, how do you keep the cord from sliding up onto the trigger? I'll have to see your setup some time.

In reply to: I would be a better climber if bolts were not everywhere. I do think there are enough bolts up and the rest of the planet should be trad. That's My humble opinion. Buy some cams with the cash. Climb On, Bill
Suuuure and get stuck climbing cracks. How do you protect a slab without bolts?

check out the Hilti TE-6A with the belt mounted battery pack..that way, the heaviest part of the drill is on your harness and not on the drill and in your hands. Could help with the fatigue factor if you end up doing alot of bolting.
