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

John, go for the new Bosch 36V lithion, smokes the new hilti and it is half the price.
Details: Here

I'm more concerned with speed of drilling and lightweightness (is that a word?) - I can always carry extra batteries...

Edit: Wow, the Lithion! Is it heavy? How does it compare to the Annihilator? (Weight vs. speed)...

sorry, just posting out loud.

that one that just got posted I believe is a pound lighter than the Annihilator. but still, at 8lbs, i think, still heavy for leading.

modified rig for on the lead bolting would be ideal. batter on your ass kind of thing, with just the plastic for the hand.

Good idea Munge - yeah, it weighs 9.6 lbs. vs. 9.2 lbs. for the Annihilator. Plus it has 2.2 ft. lbs. torque and the Annihilator only 1 ft. lb. torque.

Canabalizing the battery is a pretty easy thing to do, I did it for a bilge pump I designed to go into my whitewater open canoe, I call it the "Sucks a-lot". But that is another story. Anyway it can be modified to fit a battery belt with just the weight of the unit in your hand.

We have both John. The Hilti has a weird anomaly in it's charging system that drove us crazy. The battery packs have digital switching system (cut-off) that is used both for the charging and temperature protection. Our battery packs have failed several times due to this stupid circuitry.

I rebuilt the battery packs with sealed lead acid batteries from Hawker corp.

The Hilti operates at 36 VDC and the Bosh at 24 VDC as you already probably know. The Bosh would be lighter.

Our hilti is setup with battery as an external pack with cord.

Whoops: Just saw that you can get a 36V Bosh version now.

Walleye - If I can drill 'one-handed' without hooks I'll go for it. I wish someone could invent a 'one-handed manual drill system' with a hammer and stuff - boy, wouldn't that be cool - no electricity needed!

Maybe Deucy can come up with something!

My drill weighs 4.2 Lbs. with this modification. With an extension cord, the battery can be left on the ground/anchor. Perfect for one hand hook or stance drilling.
This can be done to the newer model Bosch too. But wait until the warranty expires.

John, it is perfect, the power button is on the side of the drill, so when the drill is above your head, it is an the right spot. After you are done drilling it hangs at your side vertically. In the years of use after the modification, would not go back to the bulky old style of drill.
Next time I am on the east side, would be glad to show it to you.

Hilti just came out with a new lithium battery that takes the weight of the TE-6A down to maybe just below the weight of a Bosch Annihilator. Also has a battery indicator, which, I've always liked on the Bosch (see how much juice is left).

Hilti also makes a newer drill, I think the TE-2A (?) that is much lighter and according to friends who do a bit of backcountry drilling, pretty sweet while still gettin' 'er done.

If you can find the older 1.7aH batteries for the Annihilator, that makes for a nice lightweight lead drill.

Or, you can do like some folks and separate the batteries from the drill, either with a fanny pack, or, by a loooong extension cord. Knew someone who knew someone (ha!) who would pack in a Honda generator and an 80 foot extention cord for a standard 110 volt power drill. Pretty light set up once you hiked in the generator. And, as much power as gasoline. Might be the old Ryobi (gettin' a burn on the thigh when that rig flipped over is kinda fun).

I'll have to say...after lookin' around a bit, I'd look at the new lightweight Hilti drills.

Cheers!

John, Kris Solem just cut his Bosch up and put an external battery pack like Loomis'. You can spend many dollars to buy super light, super powerful batteries and the old Bulldog will drill much, much faster. I think you can drill a 3" x 3/8" hole in about 20 seconds with his new setup! It's a very sweet deal. He left the handle on though.

Jan, I get like 50 holes per charge! The handle is obnoxious, gets in the way and catches on things. I did this modification for 10 other people, they are happy for their decision.
I spoke to WilPower in LA. They told me of a new Lithion Battery that takes the weight way down from the sealed lead acid batteries. Buy they are pricey.

Edit: The other problem with the handle, is that it pushes one away from the rock.
My design keeps one over their feet and close to the rock.

I never liked the handle Scott. It seems like every time I try to take the drill out of the hole I end up engaging the trigger with the back of my hand from the weight of the drill. But then it isn't my drill to bastardize. It sure is nice drilling with the new hefty batteries though. The drill doesn't even sound like the same piece of kit. It takes a while to get used to the power cable hanging there and is easy to get tangled up in (personal experience!).

Did you check out Makita?
The HR 160 is said to be very light,( 2,5 kg) but a bit slow on the other hand.
On the website of the late Jürgen Känel
there are drills of different companies compared.
its in German, but i think easy to understand

Hilti TE-6a with the new battery - everytime. They cost twice as much for a reason.
