Does anyone have any first hand experience with using the Makita BHR202Z hammer drill with the lithium-ion batteries. How may holes per battery in hard rock (granite).
Seems like a great light weight option for placing bolts on lead in the alpine.

Thanks for the post. Hammer drills are great for lead climbing in the alpine. Hand drills take way too long, esp in granite.
When we are new routing we typically lead with a tag line. When the drill is required the belayer attaches the drill to the tag line which the lead climber hauls up to get the job done.

if you are looking for alpine or in remote locations where charging is an issue, I would suggest gasoline operated SDS drill. they weight about 7kilos in an average and one small tank of gas offers 30-100 hole . I use Ryobi ER-160 and EH-1930 along with few hilti SDS gas operated and these guys are the king of SDS drills. They are super power full, easy to work with and run on regular gas (mixed with little oil).

HAve you taken a look at this:

I recall seing some guys using it to bolt some crazy looking stuff on lead. Much smaller than other systems so perhaps better for alpine needs?

I think that 7 kg is too heavy for lead bolting hard routes and the Panasonic drill is similar to my Dewalt hammer drill which doesn't work on granite....but thanks for the suggestions

The panny is a Rotary Hammer not a hammer drill so... different.
MANY, MANY people use this one (including my self) and love it. Lighter than that Makita by 1.5lbs, established track record and more compact as well. Bosch has an 18v "mini me"model on there as well but I don't have experience with that one. The 18v model has 60% of the impact force of the larger one though (2 lbs lighter)
All depends on how many hole you anticipate...

Weird - your profile pic shows you holding the one linked above?

I´ve used the BHR202 but only briefly, the drill I normally use for lead bolting and Alpine style is the BHR162RFE which is considerably lighter and I´d buy this one again in preference to the 18v model. It´s both much lighter (2.1kg + batt) and better balanced for one-hand use. I get 7-8 holes for 80mm X 10mm bolts in marble and granite per battery. The batts are small enough to just carry a spare in a chalk bag or pocket, I normally carry 5 batteries, the spares in the seconds rucksack.
The integral light is handy when you´ve screwed up that 18 pitch first ascent and didn´t take a headtorch!

Your post is over a year old but if it's still of help - yes I have bought and used a Makita, not the BHR202 but the BHR241 which is very similar but has a slightly higher output and is the same price.
I'm drilling coastal BC granite & basalt and get between 7 and 10 3/8" x 3" holes per 3amp/hr battery charge. I typically carry 2 batteries. I hear Makita may be producing a 4amp/hr battery soon.
Whether you should be bolting in the alpine or not is a whole other debate, I won't go there other than to say I hope it's not in any park or protected area.
