couchmaster - Mine looks like the one in the photo that Loomis posted above (3rd post). Don't know how many holes per charge yet but it drills quite fast - less than a minute per 3/8" hole for sure (in granite).
All my bolts have been one handed on the lead so far...that thing is heavy.

Travelin - the "Turtle" graphic on the Hilti TCU 7/36 charger is the button for [url="http://www.hilti.com/data/editorials/-12237/akku_total_en.pdf" target="new"]conditioning the battery[/url] which should be done occassionally.

For all of you with a beaten up Hilti, when I bought mine the rep told me they have a 3-year warranty. After that, you can bring it in to a Hilti store and they'll recondition it at any time for about $300 (after which it has a new 3-year waranty). Kind of a nice way to re-do the whole thing if you already have one.
Hilti makes a battery belt pack with a keeper cord that lightens up the drill a lot.
Also, my TE-6A is pretty damn heavy and I'd love a lot less weight. I kinda wish I'd gotten the new 24 volt for the weight savings.
Anyone know where you can find one of those padded drill covers?

Ten,
If you want help to rig a remote battery pack to lighten the load, let me know. I built one for a Bosch years ago. It was a big improvement.

Nice barely used Hilti (24 volt Lithium Ion) hammerdrill at the Hilti store in San Diego for $350. They had a bunch of used stuff in there (mostly demo). If anyone is in the market for a Hilti I would check your local store first.

Mr. Bachar,
I still think you should only place bolts with a hand-held drill and hammer, while on lead, and without hooks or aid, as per the old style, Kamps, Higgins, in order to keep bolting from becoming too easy. Yes it will limit what one can do, but limits are good. Or is this way too old fashioned a thought nowadaze?

Mr. Perry-
Yes I have wrestled with that thought many a time. Tough call. I actually placed about eighty 3/8" bolts by hand before I switched to electricity. I didn't place any more or less bolts after I switched either.
I do like the ability to drill one handed - then I don't even need hooks. The other thing I like is that the hole and the bolt come out closer to perfection. Sometimes when I hand drilled, the hole diameter was a little inconsistent thereby making the bolt possibly a little unsafe. I figure if I'm going to drill a hole in the rock I should do as good a job as possible and try to make it perfect.
I still wrestle with these ideas however and I appreciate your input...jb

You might try flippin' the drill upside down and squeezing the trigger with your pinky. Seems better balanced that way especially for placements at/near the end of your reach.
Also, they're spendy, but, the Hilti 10mm drill in 4" length makes drilling on steep leads easier too.
Yeah, power makes for a nicer (and sometimes fatter/deeper) hole. If you're not just climbing for yourself, a nice gift to the community to leave a solid anchor.
Cheers!

Here's some links to a couple of tests on cordless hammer drills on CONCRETE. Basically the new Bosch outperforms everything in these tests. The high-end Hilti drills 50% more holes but it uses a battery with 65% greater capacity (Bosch=2.0AH, Hilti=3.3AH). The Bosch is the fastest without question. Read the reviews for more info. The street pricing shown is via Google Product Search (used to be Froogle). Toolsforless.com has the Bosch for $560

The Bosch unit also comes with two batteries for only $10 more than the Milwaukee. Most of these units come with two batteries. I'm sure the Milwaukee is good, but the Bosch is going to beat anything in terms of speed. Milwaukee started the whole Li-Ion battery system, but everyone has caught up with Milwaukee now. If I had to buy right now, it would be the Bosch 11536VSR.

Just got one of the new Bosch 36v drill today. Will let you all know how it works out in the RRG sandstone after this weekend. I think the also make a slim line battery for it that might shave a bit off the weight. Though not a big deal to me, as I am always hanging in my harness while drilling!

Hey all. I was pretty interested in your alls evaluation and research on the different rotary hammer drills. Reason being, I just went to work for Hilti. I've been climbing, mostly trad, since 98. I have never done any installation of climbing bolts. But now understand their usefulness in the construction world and climbing world. they make a persons job a hell of a lot easier!!!!
If anyone has any questions about rotary hammers, specific Hilti, I'll do my best to help out.
Based on the current thread, I was curious what kind of drill bit was used while performing the test. As with all consumable items, there is wear and tear which can cause the performance to decrease in not only the tool but the bits.
Also was a fresh bit used for each demo and the same type of bit?
Brand new tools, used tools? How long?
I have found out Hilti tools are priced at a premium, but they are design to outlast any other tool. When purchasing a Hilti cordless or corded tool, we cover any damage to the tool, less act of God or abuse, and will ship and repair free of charge if it does need repairs. Just take it to your local Hilti center or call me I'll help you out. Also those batteries, we will replace if one dies on you for any reason for a full year! Or tell your Hilti rep, has to be done at a hilti store or online, that you want to put it on fleet and we cover the battery for 2 full years!!!
Sorry if this sounded like a sales pitch, but I think its important to consider more than just price when buying.
Anyhow, good drilling!!
I forgot to add, if you have a old hammer drill (any kind), take it to your Hilti center and we will give you a trade in value for it, even if its broke!!!

ok,so here's a question: Some guys like the hilti bolt anchors. What's the deal on them? How useful are they compared to the rawl 5 piece? Are they removable? How much are the stainless steel? Any good deals you can get on them for the masses?

I've done my setting in Maple Canyon. At times, drilling the holes directly into boulders and not into the matrix. After using multiple types of drills. Hilti is the only way to go. They cost more but you get what you pay for.

Just wandering around the web, looking for a drill recommendation, and it looks like John Bachar was doing the same quite some time ago. Ah, John, we miss you here. Is "lightweightness" a word, John? It was until you were taken away.

We all miss the guy. He left some huge empty shoes and an unmatched amazing legacy. If everyone who bought a hammer drill restricted themselves as John did, we'd all be the better off....I know for myself, the drill makes it very easy to put em in.
I would imagine that if JB was looking for a drill today, he'd get the lighter Bosch. Be aware that part of the lightness difference (a good part) comes from a lighter, less amperage battery. So any of you old dogs have the one Conrad bought and sred refers too and want to get on lead with it, get the slimpak battery. The 11536C-2 gives up some impact force, however, it appears to be smaller, making it much easier when reaching overhead and drilling.
I wonder how John was liking the new drill anyway.....
The Lil Dawg. The last 3/8 x 2" handdrilled bolt I put in came in at @20 min. and cramped arms. The lil Dawg put in that 1/2 x 7" long stainless wedge anchor to back up that rusty anchor chain there in 10 seconds. I remember John Middendorf saying he thought he held the handdrilling record of like 47 seconds for a 1/4 x 1" split shank Rawl stud. Makes you wonder how long it would take a maestro like him to do a 3/8 x 2 bolt.

WWWWWWHHHHAAAAAAAAAA??? What whhhhuhhh? I've been working at a newer soft rock area and have a couple of hundred of the stainless 1/2" x 6-1/4 and 7" wedge anchors laying around. (insert gratuitous pics here)
Hardly a crack within 20 miles anywhere. Getting holes 7" deep in 7-8 seconds pretty consistently. I understand that the Hilti battery's last much longer. I'm getting @13-15 holes per battery charge at this area.
