Good Evening all!

I am after a long masonry (about 8mm) drill bit.

The longer the better!

The longest on I currently have is 400mm, and that's too short...

I don't have an SDS drill, just a "normal" hammer type

Any idea where I could get longer bits?

1,000mm would be nice, just in case!!

Sparks...
