Hey Everyone I have been putting up some new sport routes and borrowing a friends drill. It is about time that I got my own. I want any advice you have on which drill is the best right now. Thanks

I just recently purchased a new drill that I haven't had a chance to use yet but the reviews I read were very positive. It's the Bosch 11536VSR (36 volt, lithium ion batteries) and I found a new one with two batteries on eBay for $405.
It feels heavier than the previous 18v Milwaukee I had but I'm sure it's going to be worth it to have the 36v power.
I read some good information on drills in this thread on the SuperTopo site before making my decision.

I am not sure of the name of the drill or the number but I believe it is the latest cordless Bosch hammer drill with 36 volt Lithium Ion batteries. 20 plus years of drilling and it is the best drill I have ever used. Good battery life and fairly light weight as cordless hammer drills go. Have done a few ground ups and it worked fine but it would be dicey in a precarious position as it takes a fair amount of pressure to engage the hammer mechanism. It is less force than a Hilti or the older Bosch Annihilator. It is also a little heavier than the old Bulldog but it gets more holes and a 3 inch deep hole only takes about 15 seconds in most types of stone. 1Eric Rhicard

I bought a Hilti TE6-A last year and I really love it. Hole after hole, deep and fast.

But its so darn heavy! I tend to like to like longer routes and the area I climb in has unclimbed rock far away from the road. So I'm thinking a lighter drill that could drill a few fewer holds would have been a lot nicer.

So before you jump on a 36volt drill of any kind, take a look at the 24 an even 18 volt hammer drills from Hilti. I think the 18 volt lithium is about $360. If you talked them into an extra battery you could drill a very long time. That would be very nice.

Last year I purchased the 36v Bosch Rotary Hammer Model 11536VSR . This is one wicked drill.They Claim 7.1 inches per minute and I would have to agree, even in harder rocks like quartzite. We have been putting up new routes in really hard quartzite and this drill is amazing. Also amazingly light for being a 36v. This drill has enough power/torque, all you have to do is apply a small amount of pressure and let the drill take it from there. Highly recommended. Shaun Greene

Thanks for the advice. It looks like there are only two brands to choose from, Hilti or Bosch, so that narrows down the choices. Now I just have to convince the wife that I "Need" a new drill. Jeremy H

wham bam hand jam. Wrapping up the final moves of ...
dont underestimate Dewalt. i have a 24V Dewalt that i modified and it pokes a hole quicker than the bosch. It is also a little cheaper too. i got mine on ebay for $200. left me money to buy a couple deep cycle lead-acid 12V packs. the stock batteries suck, so if you are not planning on supercharging it, than probably spend the extra cash on a hilti.

my dewalt is a bit heavy, so i cutoff all uneccesary stuff to fit in my holster. again, the trade-off is its got way more ass behind it than the bosch.

drill selection really comes down to end use, with the battery selection more important. weight, hole speed, and quantity of holes. if you are setting it up for lead bolting, speed of the hole is priority, but sacrifice some weight, and quantity of holes. if you are primarily rap bolting sport routes, than probably battery life (quantity of holes) becomes desirable.

in granite, my drill 'only' gets about 30 holes per charge (3/8" x 2-1/4") and fewer 1/2" holes. but i dont need any more capacity than that. if i do, than i have some solar panels to charge in the field. but it will drill a hole in under 10 seconds.

my too-sense.

I 2nd Darren's initial statement there. My un-modded DC212DA eats through 3.25" of granite at 3/8" in well under 10 seconds; and it's only 18v. Can't say anything definite for battery life other than trying to run it down at home i gave up after 20 or so holes and used the same pack and charge (forgot to charge it) for five more three weeks later on a route.

If you can find a used one the Hilti TE-10A 36v is the best drill I have ever had and used. Mine is supecharged on a 100ft cord and drills 4" x 1/2" holes in very hard limestone all day. KirkH

The Petzl Rocpec works as good as any. A little pricey but they hold up very well.

Does any one have instructions on how to modify a drill? I could definitely do it without instructions, but I would feel more comfortable with some guidance. Vince Arena

Hilti TE-6a all the way. You can get a belt battery pack extension for it cheap. You can also get the batteries rebuilt and supercharged for 140 bucks. Jesse Zacher

Rawl hand drill: Bit's don't fall out and you don't fuck up the rock with 10 second holes. You think, plan carefully, choose a nice hard spot that rings when you hit it with a hammer. You spend up to an hour drilling that 3-1/2" hole in granite. You make damn sure it's a worth the effort before you drill. Spider Savage

Mostly the extension of the battery pack for drilling on lead. But any other useful mods would be cool too

I have been drilling routes for 20 years and have used about every type of drill on the market. I would strongly recommend getting a lithium ion powered drill, preferably 24v Bosch. NiCad batteries basically suck, don't hold up in the cold, don't last for very many years unless you use the drill frequently, and are very expensive. The lithium ion batteries developed for the new hybrid cars are MUCH lighter and don't seem to be nearly as expensive.

A 24v drill should have all the cutting power you need and if you ever needed to you could modify the drill to run off of lead acid gel cells without ending up with a 25 lb battery pack. It is probably a good idea to be careful modifying any of the newer drills as they have electronics for evenly draining the factory battery packs in the switch. Reversing the polarity on a modified set-up can fry the switch, at least in a Bosch.

Sometimes folks will sell their drill on ebay because the batteries are shot, but if you look around you can find mom and pop shops that will recondition your batter for about $100, and they'll work better than new. I would go that route rather than buying new. Mike Anderson

I second the motion for a Bosch 11536VSR (36 volt, lithium ion batteries). You can get good deals on reconditioned ones at bosch.cpotools.com Brian

BOSCH!!!!!!!!!! Lithium Ion Batteries are a must! Bulldog is a bit big and heavy... The smaller is pretty sweet... Can't go wrong with either one. Check out TylerTool website.... Drew Spaulding

I use a Hilti 2a. Works great on sandstone, I get about about 15 half inch holes. Bought it on eBay and then got an aftermarket battery replacement. If you are going to be drilling hard rock you might consider a 36v. DrRockso

+1 if you are going to do it, do it right, something you will be proud of when you are old and grey.

Except it might also induce you not to put as many in as you should or not in the best place because it is awkward to hand drill there. You also are unlikely to use 1/2" bolts. Some might find it more fun, but the whole hand drilling makes it better thing is BS. It might help you think again about bolting another mediocre line because of the effort, but if you are thoughtful, and have a modicum of self restraint, using a power drill is better for most.
