      WELCOME TO THE CASCADECLIMBERS.COM FORUMS   02/03/18

      We have upgraded to new forum software as of late last year, and it makes everything here so much better!  It is now much easier to do pretty much anything, including write Trip Reports, sell gear, schedule climbing related events, and more. There is a new reputation system that allows for positive contributors to be recognized,  it is possible to tag content with identifiers, drag and drop in images, and it is much easier to embed multimedia content from Youtube, Vimeo, and more.  In all, the site is much more user friendly, bug free, and feature rich!   Whether you're a new user or a grizzled cascadeclimbers.com veteran, we think you'll love the new forums. Enjoy!

rotary hammer drills...

Recommended Posts

So...I haven't drilled in probably 15 years or so. At the time I was using a 36v Hilti.

 

These days, it appears that 18v lithium ion hammer drills might be up to the task, especially with a couple of extra batteries in the pack.

 

Does anyone have any experience with these? Looking at a birthday present for *someone*...

 

Cheers

Make sure you get a rotary hammer and not a hammer drill, 36V will give you a lot more energy stored per battery pack then 18V.

 

People love the bosch hammers, but Dewalt, Hilti and others all have good options now. Beware of how much the batteries cost if you buy a bare drill.

Yah Kerwin...

 

meant to say rotary hammer drill. I'm more interested in the weight of the drill. I can pick up another battery so number of holes per battery is no a big deal..

 

Thanks!

 

I had the old TE-10A. Worked great but died a decade ago...

The 18v makitas do surprisingly well. With two batteries, you could get a route done at Index. Probably not at little si. They're so much lighter than the old 36v drills, and less expensive too.

I picked up a makita 18 v for 200, bare tool. It seems I get around ten holes in granite per charge on the 3 amp hour batteries. The tool's longish, not super well balanced for one handed use, but that's really not a liability since it's so light.

 

The only other one that really tempted me was panasonic's cordless. Much shorter tool, and I think it's the lightest on the market, with good reviews. No personal experience with it though.

 

I bet your wife will love whatever roto you get her.

Check out the Milwaukee 12v. I got one last summer and love it for a lightweight drill. I know a few other people that use one and they all love it too. cheap and as far as i can tell the lightest thing on the market.

 

I was getting 9 3/8" x 3" bolts in granite per 4amp/hr battery.

 

you should come over to my place next time you are down and i'll let you put some holes in my boulders.

When did Chris stop bolting routes?!? ;-)

 

Go test Wallstein's rig. Compare it to the 18v's, but sounds pretty damn good... I didn't even know there were 12v rotos out there.

 

Where's your little monster wanting to bolt? I'm guessing there's still a lot of potential at your OR hangout, like just right of JDI haha.

Mike...Drew's got an eye on several lines at smith. Inspired by Palo to start poking around the mud!

 

Kimmo...the little freak will have his license next August. Mike keyed him into stuff up at index.

 

next year should be interesting. The kid can run it out crazy style.

3 pounds! Without battery.... I think I'll get one.

 

Wallstein: you ever drilled in hard stuff? Basalt, rhyo...

This is timely, as I'm planning to get a roto hammer to develop a potential new crag, and to do some bolt replacement (1st pitch anchors on Davis Holland come immediately to mind). Is the Milwaukee model you're recommending the M12 Fuel 5/8"? Assuming so, any reason to get a drill that has a bigger than 5/8" chuck, for glue-ins, etc.?

I haven't drilled in anything but granite so i can't say how it will work in harder rock. I wish i could compare it to another power drill but almost all the bolts I've drilled in the last 10 years were by hand and any power drill is better that my elbow power.

 

I got the 1/2" SDS plus. model number is 2412

 

There are a few others out there using these things and everyone I've talked to is super happy with them.

 

Drew should add a direct finish to To Bolt! there is probably 35ft of climbing to do up there...

Mikey have you drilled on lead with that thing? Looks way more feasible than with a two-handled Bosch where the rear handle & trigger is so far out from the wall

The goal was to drill on lead with it, though I haven't yet. i think if you were to drill 1/4" (or 8mm since you are a canadian) bolts with a short bit you could do some pretty serious stuff.
