If needing to put t-post in solid rock should you drill a 1 1/2 ", 1-3/8" or 1 1/8" hole size I thought a t-post is 1 1/2" diameter but I've heard you can tap t-post in a 1 1/8" hole This is solid rock not rocky soil
Also how deep should you dig the hole in rock
Anyone have any experience with this.

Are you putting up a fence or anchoring something down?

Fence. I've use the 1/2 " hole with rebar and that worked great for anchoring

I'm going to try using using my rotary hammer that I have and just get a 1-3/8 or 1-1/2 inch bit It worked great for the 1/2 in. Holes but now I want to try a larger hole for t- post

I've had great results with a 1 3/8 bit in near solid limestone. Some places have less than 6" of dirt/clay cover. I use a large hammer drill I got cheap at a pawnshop and a bit that will drill in 16" You may have to hammer off the t-post spades but the posts hammer in real snug without too much effort, and they won't go anywhere once in.

I checked today and my rotary hammer only take sds or sds-plus drill bits meaning the largest bit they make is 1-1/8" Do you think I can pound a t-post into a 1-1/8" hole?
Scoop what kind of drill did you get at the pawn shop? Does it take sds-max or spline type drill bits

I think the model is a thunderbolt? by Milwaukee(sp) and it takes spline bits up past 1 1/2" but nor sure of max. I originally got the 1 3/8" cuz they had it in stock cheap, and it woulda cost double to order in a 1.5".
Not sure you could get a t-post in 1 1/8" hole in solid limestone. Also, can you get enough depth with a smaller drill?

You have to be careful with the SDS bit, small shank, can break unless you go slow. Let the drii/hammer action do the work. Of course the spline is a better deal. Check some of the better tool suppliers for a larger SDS bit, Fastenal, Hilti, etc.

They do rent an electric jack hammer, if you have access to a generator.
