John asked: "What's the shiznit hand drill these days?
Does Deucy still make his system? I though his was pretty tight..."
__
I put Johns question here cause that question was buried below many megapixels of Jpegs on the Hurricane Hand Drill thread where I posted the manuel, which would pretty much eliminante our dial up bros from even seeing the question below all that stuff.
-So-
What is the current schizzel? The Hurricane was one of the best designed drills in the world for climbers. It appears they no longer even make them. Despite the proliferation of awesome power drills, people still need hand drills.
BTW, they are signifigantly lighter:-)

Bill

Edited to add: welcome John: BTW that crack pic you asked about was of Trout Creek, Elcapinyoass got it right.
Werner: I didn't forget Merry's request from the other day. Little time is needed is all.

Thanx couchmaster - that other thread was pretty slow to load.
I sold my old Rawl hand system a while ago...don't even know what's around these days.
Another weird question I have is what size hand bit do you use for 3/8"?
I used to use a slightly smaller bit than a 3/8" because the hole ends up being a little wider due to the inevitable wobble of the hand drilling process. It's been a while and I just can't remember the exact size bit I used....
Oh yeah, who made that Hurricane Drill anyway?

I'm liking the Petzl. No wrenches. I got a nice shorty bit for it too, so it's lower profile and easier for me to hit my target. It bounces, so you need to be careful that you don't pinch your hand in the bounce.
Edit...Their's also a hole in the handle that you can stick the bit in so that it's 1/2 the length so that you can have it on your harness w/ less dangle or so that it fits all the way into your bolt bag.

Petzl Rocpecs are very light, super quick & easy to change bits, and are fairly short overall length. Disadvantages are that you can only use SDS bits (a lot of Valley folks like metal drilling bits in Hurricanes with the right collet), and that the spring-loaded locking mechanism tends to pinch your hand (no prob with gloves, or you can wrap a piece of tape around the junction, but that hugely slows down drill bit change-outs). They are pretty stubby for guys with large hands. Used to be $35 for the Petzl but the price is now up to $60.
Standard 3/8" SDS bits are 3/8" at the tip but less than that along the shaft, so no problems with wide holes or drill binding (same design for other sizes like 1/4"). No more drill bits breaking right when you're nearly done with the hole. Once the flanges on the edge of the tip start wearing down, the hole will start getting smaller and you'll notice that it's harder to pound in a bolt - but most people hit hard enough to break the bit tips before that becomes a problem.
Used to only use the Hurricane, then used a Petzl as a backup to the Hurricane (ususally with 1/4" bit), then switched to 2 Petzls, one with 3/8, one with 1/4. Light, simple, no wrenches.

I've gone from the old RAWL, to the Pica (with the allen screws),
to the Hurricane (ground my own bits), to the Petzel.
I'm thinking of going back to the RAWL because you can put a
ratchet wrench on the thing and bang away while using the wrench
to crank through the hole. But since I'd have to go back to
grinding my own bits, I think I'll stay with the Pecker with
easy-to-find SDS bits. Plus, the SDS moves back and forth, which
seems to do good stuff with the roto hammers. My complaints with
the Pecker are that the same as Greg's, it's way short and the
thing pinches.
ON ANOTHER NOTE, what hammer do you use to drill? Looking at a
roto hammer, the thought occurred to me that it doesn't hit hard,
but just a LOT of times in a short period. With that though, I've
been thinking of using a lighter hammer and going into whail mode.
What ye experienced bolters think?

I have no depth perception, so I love that the Petzl is short. I think it also helps me to keep the drill straight.
It never occurred to be that you big guys would have a problem with it. Hard to believe they finally made a peice of gear that works better for smaller people.
I could live w/o the bounce though.

Started with a hardware store ball-and-pein hammer, big and heavy.
Then finally started using a BD Hammer (thanks Ted at the Mountain Shop - gave me an old used one!).
Beat 3 or 4 of those to death. Then I bought a Cassin hammer for 14.95 (Sierra Trading post), sawed off the end of the handle to make it nice and short, and I had a custom "lightweight wilderness hammer." After using it a few times, switched over to using it nearly exclusively. A lot lighter, smaller, easier to use, and it fits in the A5 bolt bag along with a full bolt kit. No good for funking though, still use the BD hammer for heavy-duty rebolting projects.

Thanks Greg, that's what I wanted to hear...
I have an old Chounard Ice Pick /hammer.
I was thinking of cutting off the pick to
make it lighter and less dangerous, but just
can't seem to bring myself around to do it.

Greg - Petzl Rocpecs, that's it? SDS bits only???....
Question: How true is a 3/8" Rocpec hand drilled hole?
I'm using the superior strength Taper Bolts from MKT Fastening and they require a pretty true 3/8" hole diameter ( I knew you'd get a kick out of that!)...
Oh yeah - I use an old Chouinard Hammer - great balance.

Oh yeah, there are other nice things about the small light hammer. You hit faster and less heavily, and so the drill bits rarely disintegrate on you (and it's easier to avoid binding the bit when expanding 1/4" holes). And when the hammer is riding in a gear loop (or hammer holster), the handle isn't as long so it doesn't get in the way of doing high steps as easily.
It wouldn't be good for driving pins just because the handle is short and you'd scrape your knuckles - it would also be bad for funking out pins.

The Pika Drill is shiet. After a few hits the allen screws start to come undone and the bit wobbles. Pain in the ass to change out bits. THe cable attached to the head as a keeper sling does not rotate so it ends up kinking and breaking. The head doesn’t mushroom though..

JB, I've never had any problems with SDS bits, and they are the industry standard in construction and with power drills. True holes as far as I can tell, although I don't really use any bolts that would be super-sensitive to perfect holes. The only thing I've seen regarding precise hole diameter is that a well drilled 3/8" hole would see the old Fixe stud bolts bind in the hole, but they were 10mm and thus slightly larger (now they make 3/8" versions). I never noticed any difference between the Hurricane and Rocpec as far as the holes. You'll have to ask some of the Valley guys on the metal drilling bits in the Hurricanes, not sure what precise diameter bits they use.
Of course, good technique is still needed to make a good straight hole. Especially since the SDS bits are slightly smaller along the shaft - thus it's possible to very slowly change the angle of the bolt hole (I've never had any trouble).
The Rocpec mechanism allows the drill bit some forward-backward play, which actually helps clean dust out of the hole as long as you don't put too much pressure on the drill.
I used a Pika once for part of a hole. I know at least a couple guys who swear by them as the only drill for guys with huge hands, I think they use light-duty threadlock on the little set screws.

Greg, do you custom sharpen your SDS bits for hand drilling?? Change the angle of attack on the insert a tad to drill faster?
Also, with 1/4" bits, are you drilling a pilot hole first, and then finishing up with a 3/8" bit? You think that's faster? Hole quality better?
Yeah, the Rocpec can put a painful pinch on ya.
I've been using a Grivel Thor for some of my bolt work (setting, mostly, but some hand drilling too, in sandstone specifically). Heavy enough to set a pin too. Pretty good cleaning tip and the handle hides a nut tool of sorts. Been a nice hammer and lightweight.
Cheers!

Hey Brian. No, don't sharpen. I sharpened some of the old ones years ago, but you can't sharpen the SDS bits now that they are all wavy-tipped (supposedly drills better, but actually keeps people from sharpening bits so the companies can sell more). Never noticed any benefit from sharpening them, and they disintegrated much quicker. Some Valley folks swear by sharp metal drilling bits, but you have to re-sharpen all the time.
I use 1/4" buttonheads with stainless SMC hangers on FAs, as well as 3/8" - depends on the stance. Properly drilled in good rock, they're good (at least for a while). I replace most of them right away. An interesting side product of doing that is finding out just how good the rock is - last fall I pulled a freshly placed 1/4" in what I thought was fairly good granite (bit lower quality than most of Tuolumne) only to find nearly no compression since the rock was a bit too soft.
No way would I drill a 1/4" as a pilot hole for 3/8", you need to drill fast and expanding a 1/4" hole is somewhat delicate work - it's way too easy to bind a 3/8" drill bit when expanding a 1/4" hole if you try to rush it.

Holy s#it, k-man!!! What are you thinking? If you really want to destroy it, send it to me and I'll send you a new Yo-Ham or similar. Have you seen the ridiculous prices people pay for that old Chouinard stuff on eBay? Seriously, collectors eat those up. As nice of a bolting hammer as that would make, it would be a shame.

A friend of mine tossed me the ice pick. He also has a mint
condition Chounard/Frost ice axe, man that thing was pretty.
He tried to give it to me as well, but I couldn't take it from
him. A day later, I saw one go on eBay for $1500 (and in worse
condition).
PS. I did take his A5 hammer though ;-) But that'll kill your
are to drill bolts...

Use the Hurricane drill w/ the Pica as a backup.
Only prob w/ the hurricane is that my pinky and part of my ring finger hang off the rubber handle. Does get loose from time to time, but nothing like the Pica style setup.
The pica is basically a copy of the old ? (I forget, but I've used it. Has set screws.) Some lock tight or something would help so it doesn't loosen up often. It does have a big rubber handle though which is nice.
One would have to get used to the "rebound/recoil" on the Petzl (have heard many complaints about this).
BTW, I primarily use 3/8" SDS bits, with an occasional 1/2" SDS and 1/4" bit thrown in. Hurricane is my preferred ... wish the rubber handle was longer!
Enjoy!

I agree, do not sharpen the SDS bits, the tip will disintegrate after one hole. I used a Petzl and my Hurricane last summer, both have their advantages. The pinching from the Petzl is a real drag when you're already gripped and on an uncomfortable stance.

I fifth or sixth the recommendation for the Petzl RocPec. I used the Rawl system then the Hurricane before switching to the RocPec. I would agree that the sliding nature of the way the RocPec holds the bit seems to mimic the way a hammer drill works. My in-the-field tests indicate to me that I can drill a 3/8" hole much faster with the RockPec than with the Hurricane. The only thing I can attribute it to is the loose(sliding) way the RockPec holds the bits.

I disagree with the Petzl drilling a hole much faster. Used them back-to-back last summer. Or maybe it was cause the Petzl was pinching my skin so bad I had to stop and curse more often.
