Question: Is this set powerful enough to screw sheets of drywall into wall studs?
Document: I had this product delivered fairly quick, packaging was good (enough to protect the contents).After opening the package, there was an added bonus inside: a 12 volt torch with 6 step adjustments (no additional battery provided, though).Both the tools work as advertised. While I did not purchase this set for carrying out extensive work, I'm perfectly happy with the performance, so far.The only complaint, if any, would be, while there was a screw-driver bit included, there were no drill bits provided along with this.
This set is under powered, even for 12V stuff. I've used Bosch, Milwaukee, Mikata, and Rigid 12V tools(all similar lithium models) and I'd say these Hitachi units are less powerful than all of the other units. I compared the specs before buying and according to the sheets, they said they are similar, but I promise, they are not. I attempted to drill 1/2" holes into PVC on high speed and the drill wouldn't do it. I had to put it on low speed and it still struggled.
I used a friend's sub-compact impact driver (Bosch 12V) to finish a deck this summer, which was enough to quickly convince me that these little impact drivers were absolute wonders for driving screws (of any size or type). They have plenty of power, they don't strip out the screw heads, and they don't transfer any torque or twist to your wrist. Impact drivers are clearly superior to drills for driving fasteners of any type. They are wonderful.So I decided to get my own little impact driver.
I got these for my son, and have been using them on his remodel of a 1940's house with plaster walls.Unlike my Panasonics, I can hold these INSIDE a wall cavity (don't drop!) to run screws for wire clamps. The batteries last good and long, lightweight and powerful. The new Lithium batteries are way better than the old NiCads. Chuck runout is minimal and the impact is perfect for the duties of an electrician, setting boxes, etc. I have run some 3&#34; deck screws into the old case hardened fir timbers- it works hard, but does the job!I decided I need a set for myself for my instrument repair- I needed a small drill to hold for interior tube polishing on brasswind instruments, and now I have an extra set for around the house, and my Panasonics are for the big stuff.The bag is well designed- i actually use it, as opposed to the plastic cases, that are building up in my shop attic!
Just bought a new fixer upper and these have been used for various tasks. Kit is great. Impact driver has been more functional than I imagined. Just installed a cabinet with it, no stripping on 3" drywall screws. Removed old shower doors in two baths, worked great. The drill is not overpowered, but I did use it with a hole saw to cut plumbing lines, had enough power to work through 1/2 inch plywood.Both tools are very maneuverable. Great for small spaces, limited width situations etc.My only minor complaint leading to 4 stars is that the Li Ion batteries offer no forwarning that they need to be charged.
Great set of tools for jobs around the house. I replaced my Dewalt screw gun that had smoked with these. Lifetime warrenty is awesome. The Dewalt went in the trash after it died due to warrenty.
Pros: This tool set should be sufficient for small jobs. The design is pretty comfortable, small and light.Cons: The advertised voltage is 12 Volt, which is a bit misleading. Actual usage is around 10 V. The impact wrench did not have enough torque as I tried to remove an old rusted bolt (even though I think that it should have handled it). The impact wrench still failed to remove the bolt even after I easily loosened it with a wrench (with minimal to medium effort).
I drove 3 1/2&#34; wood screws into a 2 x 4 with no problems. The small hammer drive unit is light and powerful, very handy. The charge lasts a long time, you shouldn't be able to overcharge and they charge quickly. My only complaint is that the free bits that came with the set are not magnetized and fall out of the drills. Overall, I really like them a lot!
First off, no tool is going to do it all, if you are drilling concrete all day long or building decks this is not going to be your primary drill set. Personally I own a few corded drills and a small collection of craftsman 19.2 (good tools but not as well made than the Hitachi).I was at Lowes when I picked up the display unit and it just fitted like a glove. I figured I had enough tools but I did mention it to my wife, and a couples weeks later, while I was going over the hill...Surprise: Happy birthday with Hitachi.The ergonomics for me is amazing, from the feel to the size and the weight.
This combo is GREAT!! Lithium ion is the way to go...light weight yet powerful. I had an 18 volt Ni-Cad and this is almost as powerful at about 1/3 the weight. The impact driver is almost handier than the drill-driver. The set also included a free light that hadn't been mentioned and tools are lifetime warranty. I am totally impressed!! Also got the set at a great price!
