Earth rod driving stud size

[Zerax]

Does anyone have the spec of the TE72, as it is no longer made seems to be a bit sparse of detail, trying to compare it with this:

• 1500W
• Drill, Hammer Drill & Chisel
• Max. Impact Energy: 8J
• Anti-Vibration System
• Mechanical Safety Clutch
• Magnesium Gearbox
• No Brake
• On/Off Switch
• 6-Speed
• Replaceable Brushes

Mostly interested in the Impact Energy.

I don't have my set of "Top Trumps" for hammer drills with me right now...

That's a surprise.

Can be difficut to find out very much of anything about Hilti, beyond prices and details of maintenance contracts.

Ah but the RB22 Auger was much better. ?

Good little machine,as a manual...on air,they were a bit unpredictable,first thing,on a frosty morning

All I wish to compare is the Impact energy between different machines, my Hitachi SDS @ 3.2 joules is a bit of a lightweight, however the cheap and cheerful Titan @ 8 joules is a bit of a beast in comparison, drills into concrete and Granite without much of a problem, but is very heavy to work with free hand.

Can't find much on the TE72, but the TE80 is 11.2 joules so it does look as though the TE72 may be better than the Titan at driving in an earth rod.

Drilling is very different to driving earth rods I don't think you should drive rods with an SDS constantly unless you have a big budget for new drills

The breaker I carry for daily use is 39 joules "blow energy" according to the manufacturer

I bet you have big biceps, I'm a weedy OAP don't even think I could pick one of those up, let alone use it. ?

I am also a few hundred miles away from my workshop, hence the question, thanks for your input guys, I think this is what I need: https://www.ebay.co.uk/itm/Kennedy-5-8-A-F-Impact-Socket-1-2-Sq-Dr/114465887524?_trkparms=aid=111001&algo=REC.SEED&ao=1&asc=20160727114228&meid=6703839bd388492590751377f8365c2a&pid=100290&rk=1&rkt=4&sd=114465887524&itm=114465887524&pmt=0&noa=1&pg=2060778&_trksid=p2060778.c100290.m3507

The Socket has arrived and its 26mm across the flats, thanks to those that helped especially Julie for the vernier calliper picture and measurements.

Amazon sent me this link today: https://www.amazon.co.uk/gp/product/B07ZTQMQJ7/ref=pe_3193591_547463921_em_1p_0_lm. Looks as though it's just a plain shaft, no thread and over diameter would probably bell over the end and make it impossible to attach a second rod, looks like the best idea is the driving stud and impact socket.

Sent from my laptop using all my fingers

There's no way I'm clicking on that link... I hate to think what might come up !!

Having spent some time in the Piling job,where motorised percussive driving,is usually faster and easeir,i prefer using an old TE72 hilti,and that gets through most materials,given chance.

I wouldn't be shy of using a sledge...i own two 56lb items,which nobody is rushing to borrow,but they are used with the acceptance of damage,to both animal and mineral..?

.....i actually got an eemoji to stick....Trump will be gone,before i work out how.....

Just wondered if you would be interested in selling one of your 56lb items?

 

[Mike Johnson]

The cheap Triton SDS drill has 5.5J of power and even though its heavy once on top of the rod drives it in with ease, less strain than a 56lb sledge.

Hi,sadly no.....got an acute aversion to releasing tools in to the wild (tool hoarder)
I would imagine there are a few unused examples out there....too much for the smart phone generation - gym or no gym

If i remember,one came from a pals grandad,years before i was capable of using or needing it,and the other came by chance,with no shaft,from an architectural supply place called Bygone Times,at Eccleston....not sure if still in business.

Not the only stupid Thor themed tools i have....got an inch and a half diameter,6 foot prybar...a 36" steel set square which weighs 15kg....coroner is gonna need an engineering almanac from last century...to correctly identify the ridiculous tool i'm found lifeless,under

Take care. Roy

I'd be asking why she wanted to go in your shed!
