Thread: Impact Driver!

Haven't seen a battery powered one till now. They are readily available for pneumatic systems, and they sound great (for us motor racing fanatics ) I got one in a kit of air tools, and although I didn't think I would have a legitimate reason to use it (making motor racing sounds while doing up and undoing a specially mounted bolt in the shed wall doesn't count as legitimate ), I found it worked a treat on some rust-frozen bolts.

G'day,

Nah, that ain't an impact driver. For me it's the thing I grab when I've got very stubborn screws. Something that you give a good bash and makes lots of noise.

Impact wrench......or Rattle gun is what I've always known them as, seriously good for some work, very dangerous in the hands of idjits, specially if they'rw working on your machinery and a torque wrench is the tool they should be using .

I have an electric Makita Impact Driver (or as Bruce says a Rattle Gun.) which I used to use to install Roller Doors, Panelift Doors and Tilt-a-Doors as well as that I used it for erecting sheds.

This is an indispensible tool for those applications and I would have loved to have a battery driven one at the time but they wern't invented then provided it had the power of the electric one.

I used it for tightening Dynabolts, driving coach bolts and tightening 16mm construction bolts in sheds. Beats a ratchet spanner hands down and very fast compared especially when you needed to undo them as well.

Hmmm, digital clutch.

Does that mean it either works or does not work?

Wow. :eek: :eek: :eek:

That's really $^%#$^%$ expensive, scary even.

Uhh, they be pretty thick on the ground around here, and I don't own one since I learned how to use a regular cordless drill for driving screws.

They do make it much easier for the hamfisted folks I have found, which is good and bad.

(Next time you want to, say, drill a hole, you will find out how well these things replace a proper drill...)

Agreed - rattle gun pictured, impact driver is hammer powered!

Het Schtoo, I'd not be reaching fer one when assembling a cabinet, but when assembling a GTHO, horse for courses an all that.
I still don't reckon I've got ham fists , although my kids reckon I have got sausage fingers, what you get I s'pose from a life spent in the timber game

1060 inch pounds - that's ~88 ft pounds. All that torque through a 1/4" hex shaft :eek:
That's 2/3 rds the way to typical head torquing values, and you'd use 1/2 drive for that usually under constant pull.

Like to see how tough it really is pushing 88 ft pounds day in day out through such a puny final drive shaft - especially as an impulse drive.

Caveat Emptor methinks.
Yeah I agree, mash hammer and hardened tips with a spring loaded thingy in between is a real impact driver.

I just had a relook at the specs on that tool. That would not be capable of driving a 16mm Hi Tensile construction bolt to hold a shed up or drive a 3/8 100mm Coach Screw into hardwood without going into failure mode.

This is more like what I was thinking of.

Roofing or putting up steel fences a must , the early Makita had a chuck prob but the latest are ok, the pros I talk to like the bosch units.
they are obviously for specilised jobs , but as I said for roofs , fencing a must

I picked up a dewalt DW056 on ebay for $105 (without batteries). I already had 2 when i got my cordless bradder. Probably the best and most useful tool i have.. Will drive 100mm batten screws into hardwood with ease..And i just screwed a roof off and being so light and small its much easier than dragging a powered drill up there. It starts spinning at about 2500rpm but under load drops way down and that when the impact starts.
Great for any type of screwing. I use it to hang doors and is perfect for kitchen cabinetry.
Superb tool. A must have in my opinion.

I got the Dewalt DW056 with 98 feet pounds - the best screw in town
Bought it when I had about 300 screws to put into hardwood - no pilot holes just screw.

Ive got the Japanese version (National), brushless motor impacter.
Great for fences,sheds,impacting bolts in concrete etc.
Put about 1000 screws in yesterday, with no pilot holes. Made the job easy,didnt even have to change the battery
cheers. Gary.
