No, I mean need to gain an extra metre over and above a metre long bit.

Might have to cut and shut an extension rod.
Buy a new drill bit on the small K tapper then but an adapter small_large K taper ,weld the adapter in a piece of 26mm tube on both ends then you will need a sds- K taper drive for the drill

I doubt the standard size sds will be strong enough ,soon twist the shank off ,,you,ll have to use the sds max which is much stronger ,even then its asking alot to drill into that depth

There'll be a lot of torque in the bit, but not drilling full depth. :eek:
Just enough to get the bottom of rebar into solid stuff, then fill wall.
Might have to drill in at the bottom block on angle, drive rebar into angled hole from top, then fill wall.
Bodgetastic.

I had to do similar once, got a piece of tubing that was a tight fit over a 12mm sds bit, welded it on then welded another knackered bit in the other end to drive it, pretty bodgetacular but it drilled approx 50-60 holes before it cracked the weld, luckily at the drive end so just welded it back on and done another fair few holes

That's the plan. Unfortunately some of walls are under a low leanto roof so might have to bend drill at 90 degrees to get it out. :confused:
