TEMCo TH0405 – 1-1/8” / 30 mm Hex Shank Demo Hammer T POST DRIVER ATTACHMENT

I bought this T stake driver to fit on my import demolition hammer. I'm using it to drive in tent stakes for a commercial tent. Works perfectly. What used to take a considerable amount of time hammering in stakes with a sledgehammer, now takes effortless minutes.

This thing saved my old butt from a ton of pain! Ground is hard here in west Texas, and with a reg t-post driver I was about to give up. Drove 28 t-post in about 2 hours with this attached to my demolition hammer. It has its own special place in the tool box because I Love It!

Not 1 - 1/8" shaft. Measured with calipers at 1.25" (1-1/4") shaft. Will not fit into Bauer 1632E-B which accepts standard 1-1/8 in. hex steel bits. Additionally, the locking surface is milled across the face (flat portion) of the hex shaft rather than bisecting the corner as shown in the straight heavy shaft graphic on the "Pick your t-post driver to match your t-post driver" page.It is heavy duty and I really wanted it to work. I meticulously milled the shaft thickness to 1.125 inches and cut the locking surface across the corner of the hex bit so it would fit in my demo hammer, only to find it was too short for the internal workings of the demo hammer to contact the shaft and drive the t-post.Very disappointed. Wasted half a day trying to get it to work. In the end, I resorted to using the old fashioned manual t-post driver and getting more of a workout than I wanted that day.

I used this is a couple different but effectively identical jack hammers. The XtremepowerUS 2200 watt and the CCTi 2200 watt. It hung in the CCTi jack hammer. I think that jack hammer is slightly defective. It drove 90ish posts very deep into hard clay soil. Mission accomplished.

This thing has been an absolute life saver. So far no issues with it and this thing drives t posts with ease. I was getting exhausted from driving just a few 7ft t posts and it was wearing me out. We have a combination of two different clays and it's extremely difficult to drive t posts. This thing saved me so much time and I was able to to drive 15+ t posts in no time. Still have more to drive but this thing is gonna make life so much easier.
