I like the drill on me. That way no fuss or muss.
I want to try John's method of the drill in a quiver of sorts on your back.
I also want to practice Kris Solem's method with a custom fifi.
But with the baby Bosch one could devise a cool holster for it all Django-like.

Come On Spring! ;D

What is Solem's method?

It was described a few times in the Taco stand....would have to revisit it myself before venturing out.
But it involved the drill hanging on the last bolt with a hook that could be tagged from up above when at a stance.
The drill I believe was also on belay.

Ger, I think SoYo Climber described that approach in this thread awhile back - sounded similar anyway, with a fifi and tag line, etc.
Barry Chambers has been doing this too, from what I understand.

But don't they have drones now that can bring your drill up for a perfect hand off (as well as taking the quintessential mag cover worthy hero action shots)??

Lol Nate about the drone. Jerry, :) you boiled it down quite nicely.

Anyone going out there this weekend? Or rather warmer climates? We were free to but... so nice at home right now. Hard to motivate in the dark so early and with rain predicted through most the morning...

Irwin, the EU supplier for 10mm bits does not make a shorty 3/8" bit, which is relevant to the topic since a shorty bit might be less likely to open a 3/8" blood spigot in your calf, also less likely to be a hot bit on a nylon rope.

I'm pretty sure Fixe has 10mm bits as well.  Don't see 10mm bolts, but the bits are advertised.

A potential downside to a system like Kris' is that with the drill hanging from a hook, or fifi, it can come off and possibly pull the climber off.  It may be belayed but it can still drop enough to cause a problem.  To each their own, whatever one is comfortable with.

Now that I'm using those short SS wedgies, I want a good snug hole. The 10mm is slightly bigger, so not going to bother even trying their shorty bits. I guess I just have to stick with the longer 3/8" bit. :(

Dan found some of the short 3/8 bits. They are almost too short since you pretty much drill past the flutes for the short wedgies. I used one with one of Dan's hand drills and it felt like my finger was going to get pinched between the rock and the base of the drill. Otherwise a very compact setup.

I still have a few of the shorty bits but most of them don't seem to last long. I think Bob blew out three of them drilling one hole. I'd be happy to let somebody try them since I don't plan to use them. The 3/8" and 10mm bits are very close in size. My old (1994) copy of ANSI 212.15 "Carbide-Tipped Masonry Drills and Blanks for Carbide-Tipped Masonry Drills" says:

3/8 diameter is 0.398" +0.000 -0.008
0.398" to 0.406"

10mm is 10mm +.045 +0.20
0.401" to 0.411"

Simply measure the bit and grind a few thousandths of the sides of the tip.

Weird how the bits for a 3/8(.375") hole is closer to 10mm(.394").

Wow three broken bits for one hole is a pretty bad drill bit brand.
