Requirement for large drill hole depth for Post-installed Rebar

I've just completed a rebar design using N20 bar with embed depth 700mm, how can I drill a hole that deep?

An N20 bar requires a minimum hole diameter of 25mm.

For hammer drilling, use TE-YX drill bits 25mm up to 800mm working length or a hollow drill bit, TE-YD 25mm in near 1 metre length for a safer job.
