Milwaukee 2665

renosteinke's picture

This is a cordless impact driver with an unuaual 7/16" HEX chuck. AFAIK, there are no competing makes.

What has a 7/16" hex shank? Self-feed bits and hole saws.

Intended use: replacement for Holehog or other right-angle drill.

Verdict? While the hammering action is a lot louder than the usual impact driver, the tool is wonderful. NO torque back to you, so this thing won't be tearing your arm out of its' socket.

It uses the same 18v. batteries as many other Milwaukee tools.

Downside? No bit storage space in the case. I'd also like to see an LED light in the nose.

You had me going there.  The tool you list is an impact wrench, not an impact driver.  They are different tools.

I don't get your point.

My tool with the chuck for 1/4" hex bits is called an impact driver by several manufacturers. This Milwaukee tool is exactly the same in use, and appearance, save for the larger 7/16 hex chuck. That is, it has a hole you slip the bit shank INTO .... rather than, say, a square pin you might slip a socket ON to.

If anyone ever starts making socket drive bits for this chuck, this thing will be the bee's knees for driving in lag bolts. Ditto for the usual auger bits.

In any case, both tools hammer the bit "around," rather than "in." A tool that hammered 'in' would be a hammerdrill, rotohammer, or the like.

Not that it matters to me ... call it 'chopped liver' if you like ... but either buy one, or continue to fear the Hawg.

if it don't matter to you..... (post #206072, reply #3 of 9)

it don't matter to me that they are two different tools. 

There are impact drivers and there are impact wrenches.

Perhaps you would care to enlighten us? What, exactly, is the difference? Or, is it but simple word-play?

Does Jim's explanation suffice?

They are not the same (then read Jim's message again).




And if anyone who doesn't know it and goes on a tool buying venture-bet they wish they knew.

Cordless impact wrenches and impact drivers utilize a hammering action to apply torque to fasteners and are powered by battery power that comes in a variety of voltages. The main difference between a impact driver and and impact wrench is that the driver provides positive engagement while the wrench does not.

What is the difference between an impact driver and an impact wrench?

There are 2 main differences between these tools. The most obvious difference is that, generally, an impact wrench can provide much higher torque than the impact driver. For example, a strong driver can reach around 1400 in-lbs of torque, while an impact wrench can deliver more than 300 ft-lbs (or 3600 in-lbs)

Secondly, a true impact driver delivers a small amount of downward force while the impact wrench is purely rotational. This helps the impact driver get much better engagement of the bit in the fastener, and is part of the reason why they strip screw heads much less frequently.

As for usage, an impact driver is targeted more toward fasteners like screws and smaller bolts, while the wrench can be used for much larger diameter bolts and nuts (like car lug nuts).

Thank you, Jim, for at least (post #206072, reply #7 of 9)

Thank you, Jim, for at least trying to answer the question of 'what's the difference?' Just re-iterating 'they're different' doesn't help anyone, though some seem to think it does.

I sure can't tell / feel / hear any difference in using the tools. That is, comparing the 1/4 hex 'driver' and the 7/16 hex "wrench". One has a larger chuck, and that's it.

So, I'll call them a 'distinction without a difference.'  Sort of like the engineering geeks who assert a difference between a '2-way radio' and a 'transciever.' Or the interior decorators who distinguish between 'lilac' and 'violet.'

Meanwhile, this Milwaukee will have an honored place on the shelf, right next to my Harbor Freight, and other, quality Chinese tools.
