Can anyone explain what these tools are for?

[deepdrop]

I received an 18 volt Makita tool set for a gift. It includes a couple of tools that I don't know how to use properly and the manual is pretty useless.

One is a "cordless percussion driver drill". This seems to be just a regular cordless drill, but it has three settings. One for drilling, one for screwing (no jokes please) and one for "hammer drilling". What is "hammer drilling" and when do I need it?

The other tool is a "cordless impact driver" and it seems like I could put a variety of bits on it, from screwdrivers, to nut drivers, and even drill bits. Does anyone know what differentiates this from the hammer drill? Again, I'm not sure in what situations I would use this.

They seem like great tools and I'm sure I'll get a lot of use out of them once I know what they can do<g>. Thanks for any help from someone with more experience than I have.

The "hammer drill" mode on your Makita is used with masonry bits for drilling into concrete, brick, or stone. It imparts sharp blows to the drill as it rotates just as the name implies. You will not feel any hammer action while the drill is operated unloaded. When you bear down it will vibrate strongly as it drills. Never use this mode with a regular drill bit.
Your cordless impact driver is an electrically driven, less powerful version of the pneumatic impact wrench you have probably seen used for lug nuts at tire shops. The type you have is mostly used for loosening stuck nuts & bolts.
Congratulations, Makita makes good tools that will last the casual user a lifetime.

Hey Deep, sounds like a pertty nice combo set you got there!

The hammer drill is what you would use when drilling into concrete, block, or any other masonary type material. A hammer drill spins the chuck like a regular drill but hammers the drill longitudinally. (make sure to use a carbide tipped drill bit for this type of work)

The impact wrench is what you would use loosening/tightening bolts/screws/whatever. An impact wrench just uses blows to spin the chuck (well, the square stub that sticks out the front of the impact wrench).

Hope this helps...Enjoy those new tools!

I have no idea. Please ship the tools in question to my house immediately. I will do a free analysis of these tools and ship them back to you as soon as I am done. I will post the results here on the forum. I have a backlog of testing to do. It may take me up to 1 year to return the tools in question. Sorry for the inconvenience.

Sounds just like my neighbor.

Thanks for the explanations! And Chris, thanks for your kind offer.

It sounds like the "car guys" show where they present the week's puzzler and suggest you send your response on the back of a delta 50 inch table saw with unifence system, three point locking system and hairline pointer with built in steel tape...or you can just email us your answer.

Anyway, it's very nice to have a community of people like the ROC. I wish I had friends like you guys in "real life". Maybe I'm just getting sentimental because it's a new year, or maybe I'm just going crazy from all this snow in NH after living in Florida for 15 years!!!!
