Buying hand drill. Advice?
|
Like the title says, I'm looking to buy a bolt kit. I will be mostly looking to put in rappel and belay anchors on new back country trad routes. I want to start with a hand drill due to the weight, cost, and few holes I will actually drill. |

Find somebody to teach you. Hand drilling is a lot more complex and involved than using a power drill. And then there's also all the concerns that go into putting in a bolt in the first place, such as prepping the rock so the bolt and hanger can sit flush, drilling perpendicular to the rock, etc. |

Don't |

No one should be recommending a bolt type without first hand knowledge of the rock you're dealing with. |

Get a Petzl Rocpec. Use 3/8 inch X 3 in. stud bolts. And hey, look. Here's a video. |

How big are your hands? Mine are large andni love the fixe drill. The hilti bits are the best bits and if used correctly are warentied. Cheap bits from dewalt are fine and come from the same factory as bosch. |

Rob, curious why offset diagonal is the best? thanks |

Best drill bit? Where to save money and where to shell more out so I have something that works but doesn't break the bank? Tips for someone new to this? Thanks.What kind of rock? |

Just an opinion grog, I like 1 chain 2 links 1 ring. I also think by limiting the inward vector you can preserve the hole and limit twists. |

Cheap bits from dewalt are fine and come from the same factory as bosch. If you place studs, make sure you place some in boulder to get the torque correct. Studs require a really precise torque. Please set your anchors offset diagonalPretty sure you mean 5-Piece (3/8 SS in particular) which have a greater risk of shearing off or worse, being close. Studs are more tolerant of under/over torquing. Not that you want to of course. With Stud/Wedges, hitting the correct torque lets you know the bolt will hold its listed strength. It's a torque controlled anchor. |

Will be placing in tuff, basalt, andesite, and granite. My hands are probably a little smaller than average adult male climber hands. I appreciate the "don't" sentiment but its for ground up back country trad routes, not crag construction projects. No desire to haul the Hilti up some multi-pitch choss climb 10 miles from the car or try to free close to my current OS best with it hanging on my harness. |

IMO sometimes people pay more attention when hand drilling bolts,, a good thing. Look around for the best placement, really flatten the drilling are before starting, frequently blow out the hole..etc |

I've used both the rocpec and the Fixe drills. I much prefer the rocpec. I prefer the smaller profile and tighter feel of it. The Fixe clanged like a bell and was cumbersome. If I recall correctly, changing bits on the Fixe involved removing screws or something too, whereas the rocpec system is easier and can't be dropped. |

Be responsible in backcountry areas, ask yourself if your chosen line is a worthy route, and use bolts as a last resort. Particularly in Wilderness areas the Forest Service is watching. |

Ya, tougher than it looks to do it right |

Please set your anchors offset diagonal Run us through the reasoning behind offset and diagonal. Makes no sense to me. |

To Mick's point: it takes some skill to hand drill for a mechanical bolt in my local tuff. I know some vets who can pull it off, but I find it difficult to drill out a perfect cylinder, and the margin of error is smaller in soft rock. I'm replacing several bolts with glue-ins for this reason. Guaranteed I can hand drill a near- perfect hole into a rock in my backyard, but it's another story when hanging sideways off a cam. Why use hand drill? Wilderness area. Short of a really long approach, I don't see another good rationale for hand-drilling these days. There are some surprisingly light hammer drills. Plenty of discussion elsewhere on MP. 3/8" Powerbolts (5-piece, DeWalt) would be my choice for what you're describing. They engage well in imperfect holes, and are strong enough. We had to break one once and gained a lot of respect for this unassuming little bolt. They're not cheap. |

Stainless Steel 1/4" is a bit sketchy. I do all my wilderness granite work now with 3/8" X 3" Hilti KB3 or Kb-tz. THIS IS INCORECT INFORMATION. SEE FOLLOWING RESPONSES. |
