Petzl Rocpecker Hand Drill
|
Hi , I found a cliff around where I live a couple of years ago. I inspected it last summer and the rock seems to be solid and of ok quality. |

Hand drills suck, especially if you're going to put in beefy rap/TR anchors. Unless you're drilling in sandstone, and I assume you don't have much of that in Quebec, you're looking at 1/2 hours per hole at least. My reference is 3/8" x 2 1/2" in granite, for TR anchors you might want to go beefier, which means more time. |
|
Drilling by hand really, REALLY sucks. I hand-drilled a 1/2" x 5" hole in sandstone last week with my Rocpecker hand drill and it took 45 minutes-1 hour. If you've got lots of time, patience, and a high pain tolerance (my wrist is still a little sore) then yes, you'll be just fine. Otherwise, get a cordless rotary hammer drill. |

Sounds like you want to look up a local or two with bolting experience and maybe practice on some out-of-the-way choss before you launch into this one. "I have never installed bolts but I've climbed at a lot of sport cliffs" is a lot like playing a doctor on TV... |
|
Hand drills also have a tendency to drill slightly larger holes...with expansion bolts and little experience this can get dangerous pretty quickly. You also go through bits faster because hand drilling with a dull bit is unbearable(50 minutes of numb legs and tink, twist, tink, twist unbearable)while with a power drill only a couple minutes are added. I also agree that it is worth watching someone who has done this before...its not a public service if your bolts rip out and kill someone. |
|
Thanks for the advices... I think I will hold off on the hand drill. |
|
The hammer drills I have used took a while, those were only 18 volt though...I suspect if you got the right one it would work ok. Nothing beats a good Bosch or Hilti rotary though in my opinion. |

You don't necessarily need to spring for a Hilti or Bosch. I'm a student, too, and couldn't afford one of those. Here is the drill that I have and it works great. Not a bad deal (I paid $30 more for mine). When my batteries were new I could get 12-15 3/8" holes in limestone. Someone will probably come up and say "Don't mess with anything but Hilti or Bosch" but I've drilled hundreds of holes with my DeWalt and have been happy with it. I've used extensively my buddy's 36v Bosch and have seen no significant benefits. Here's (it's in a post by Todd Gordon) another testimony of the DeWalt. |

Just buy the hand drill. They are cheap. Sure, you are at 1/2 hour per bolt, but you save a lot of money. If you install a few anchors and get the bug then you will have a lot easier time justifying the large cost of a "real drill". I'm sure you can find an hour to install a TR anchor. I started off on the hand drill and after about 10 bolts in bulletproof granite, I decided the cost of the power drill was worth it. The hand drill is a LOT lighter and better for crags with long approaches and few bolts. |

I second the hand drill. Practice on a boulder, then go up there and sink a couple top anchors. Make sure you consider how the rope will pull and the right locations. |
|
i also like the hand drill. with patience and technique you can get a near perfect hole. As with most things, the key is in the body position and rhythm. They are a great back-up to the power drill, and will save you money on bolts... |
|
It's really no big deal to hand drill, it just takes some patience, and you'll get faster. Regardless of what you get, listen to Rob and practice on small boulders/large rocks (not bouldering boulders!). |

Greg Barnes wrote:Over-torquing bolts is the most common mistake (one that even experienced bolters make), and you can snap even 3/8" bolts with a short wrench. Hand drills have loads of advantages - weight, size, battery doesn't run out, etc. Learn with one and it will also teach you to limit your drilling to what's absolutely needed. It's also a good base skill to fall back on if you later start power drilling and the battery runs out.i once sheared a bolt by over tightening. pretty sobering. greg brings up a good point, bc it is possible to over torque a bolt and it could hypothetically start to yield... then suppose some poor dude whips on the thing... yikes! i use short wrenches. they are the cat's-ass ratcheting snub ones. save more knuckle skin that way. |

My vote would be for you to just use a hand drill. |

The drill was $75 (!), batteries will cost another $40, a charger will be $20, plus wire and stuff should be another $20 at most. (Search on Supertopo forums for info on how to do the conversion). There are lots of options... -TristanTristan, I just converted my Bosch Annihilator to an external battery pack, using much of the advice from Supertopo. If you're interested, or anyone else, I can share what I did, which didn't involved taking the drill apart. I set it up so I could go back and forth from a single standard battery and my external battery pack. Works outstanding by the way. |

Consider, also, over-torquing your bolts [by a few pounds] then backing them off to the correct torque. This will help reduce bad bolts; i've snapped a couple doing this. Any metal is susceptible to irregularities and flaws regardless of whatever fancy standards and acronyms the manufacturer "adheres to" and slaps up on their pretty web page. Assume nothing, iow. |

sorry got distracted. Daryl Allan wrote:I think you should place about a hundred with a hand drill before buying a cordless. Or at least a few dozen.best advice yet. almost a rite of passage. |
|
Nobody with a hand drill has ever said "what the heck, I'll just slap another bolt in there..." |
|
I think everybody who wants to bolt should have to in fact drill by hand first until they figure this out. This will really make you think twice about drilling,true. It is also a necessary learning experience to be a good anchor placer, route setter, and thoughtful balancer of nature and desire for the sick new send bra. Place at least twenty by hand, do it right, do it clean, use the best hardware and then see how you feel. |
|
Agreed... also, for best results while using your pecker, be sure to maintain a firm grip on it, whacking and twisting with a steady rhythm until the correct depth into the hole is reached. |

The rocpek is nice in that it needs no tools to install and remove bits. The flange to protect your hand could be bigger but if you have any carpentry experience you should be fine. |
