Customer Review: Suprising power for such a low voltage tool
Summary: 4 Stars
I purchased this tool after I was unable to find any reviews about it, but figured that I could use the batteries and charger for my impact driver and drill even if the rotary hammer didn't live up to my hopes.
After 2 days of use, I am pretty happy with it. I think that it will drill about 80 or so 5/32" tapcon holes in hollow block, or around 40 5/32" x 2 1/2" holes in concrete per battery. Obviously, compared to a corded SDS drill, the panasonic is no match, but for small projects, it works great.
I have been hanging cabinets on block walls and find the relatively light weight tool to be comfortable to work with.
I have yet to use the supplied shoulder strap because its not extremely easy to attach and remove.
The RPM's on this tool are a little low for must drilling applications. I just don't have the time to wait and would rather use my cordless drill or impact instead.
It includes an adapter to use 1/4" quick connect bits for drilling and driving. Its a nice addition, but one that I don't think I will use very much.
Just for fun, I threw in a 1/2" x 4" bit and had the buried in a concrete slab in under 15 seconds with no problems.
Overall, I am happy with my purchase. If I didn't need the batteries, I would have looked into buying the larger Panasonic rotary hammer drill. Since I think that this tool will only see use about 20% of the year, I'll give the batteries a workout in the drill and impact, and maybe a cordless jigsaw some day.
