Does $550- include more than one battery? and the charger?

My preference would be Hilti over Bosch.

I have this guy, small compact and long battery life. I recently bought the 6.3 battery for it and was able to drill 14 3/8x3.5" holes in limestone and still had plenty of battery life left. The one drawback with my drill is getting the hole started, once you do get it started it does fine. My guess is that with the drill you are looking at it has more torque and you won't have that issue. All in all I have been very pleased with my 18v Bosch

Agree with Batrock on the 18v Bosch drill. These 'baby' drills are super light and easy to lift overhead when going GU and or hanging them off the harness. But getting a hole started seems to be not as easy as the previous versions of Bosch drills.

To compensate for that I tend to buy more fresh new bits than I used to. I use the Bosch SDS plus bits you can get a Lowes for 7-8 bucks each. Cheap and easy to obtain. They have a point at the tip that helps with starting the hole.

It appears from the specs you posted, that it doesnít drill deep enough holes (?)

Damn. I thought I put a link to the thing.

It has some sort of power ramp up which is said to make for more precise bit starts. I wonder if this is what you guys are experiencing when you say it's tricky to start. Did they fix something that wasn't broken?

Jaybro, I hope those numbers are diameter.

Go big for a Hilti, the extra expense will be worth it. I will never buy another Bosch again. The problem is not the batteries or the power, rather it is the mechanical connection between the SDS chuck and the motor shaft. It seems stupid, but the slightest sideways bump of the drill bit against the rock while dangling from your harness will cause the system to be out of alignment, resulting in a wobbling drill even though the drill bit is not bent. I have had this happen twice and it cost me over $150 each time to fix it at a local Bosch service shop. For some reason, the attachment system is a poor design.

Definitely also get the Hilti four point drills. They are more expensive, but drill extremely fast and very straight (when not used with a POS Bosch drill).

Climberdude, slightest I think means a bump to your hip, but did it get dropped with bit in it? Can you give more detail?

Weigh it without the battery.

Munge,

I did not mean that the drill fell onto the drill bit, but rather when I carry it on my harness with the drill bit in the drill, the end of the drill will occasionally lightly touch the rock. This is enough to cause the SDS chuck to go out of alignment on the motor shaft.

Now, I carry the drill without a drill bit in the chuck, but the effort of putting a drill bit into the drill each time you want to drill on lead from stances is horrible. Bosch drills are POS.

I have also learned that many drill companies make different size batteries that have very different weight. If you want a ground up drill arrangement, get the smallest battery pack. If you are going top down or massive bolting where weight is not so much of an issue, get the larger (more mA-h) battery pack.

I'v gone to the 12v Milwaukee rotary hammer. For lead climbing they work really good. They drill a pretty fast 3/8" hole, and you can't beat the 4 pound total weight. They work with a pneumatic actuating piston so they have a light feel that they aren't going to push you over backwards. They have a short body, and they are surprisingly powerful. Awesome little tool, really! About $300 from Home Depot, with 2 x 4ah hour batteries and 1hour charger.

Weigh it without the battery.

Specs say 6.2 vs the 36 volt 9.7. I assume that both weights are with the battery.

the end of the drill will occasionally lightly touch the rock. This is enough to cause the SDS chuck to go out of alignment on the motor shaft.


I've used a lot of various Bosch drills. I've dropped them, fallen with them, backed over one with my truck once (it was on soft ground to be fair.) I even had a hook blow when I was about halfway in the hole, I ended up hanging by my hand from the drill, bent the bit almost to 90 degrees before it broke, at which point the drill and I went flying. The drill was fine.


I've never seen the problem

My cheap AF used Dewalt took a 100+' crashlanding on talus and or scree inside a broken attachment'ed BD crampoon case and still gets it done. I don't drill granite for the most part though, and still need to run a head to head against my buddy's new Milwaukee

Specs look good, the price maybe not so much:-) I have no experience with that model, but have seen that Bosch make some of the best rotohammers. I have the old school Bosch 36V and the newer lightweight 36V and they both rock the house. We were drilling some hard andesite (so harder than granite) a bit ago, and buddy brought up his brand new lightweight Milwaukie. It got 2 holes per battery charge. The light weight Bosch got @ 14 or so holes with the lightweight battery. Drilling overhead with an extra 2 lbs is not that easy when your shoulders are tweaked.

BTW, my heavy Bosch has well over 1000 holes drilled and it's going strong. Both drills have been bumped many many times and I haven't seen the wobbly effect described upthread yet. I'll likely sell one of them now as I got old and don't need 2 drills.

Climberdude,
Iíve had 3 boschs and never had this symptom so I think you got one bad build. Iíve dropped mine, dragged it and stuffed it in packs. No issue with alignment.
