Long wood auger + extensions

[88v8]

I need to drill some 16mm holes a little over 4ft long.
Oak cross-grain.

I can see some 39" auger bits, but am struggling to find extensions. I've asked Timberfixings, UKtools, Famag, but no useful replies.

It would surely be simple enough to go into the warehouse, get hold of an auger and see if it fits an extension, but apparently not.
Perhaps they can't be arsed, or perhaps none of them actually have these things in stock, they just order them in.
Grrr.

Anyone know of an auger/extension combo?

It doesn't have to be cheap.

You can get 1250 x 10mm , then open it up from each end with a 16mm bit .

Gosh, would have thought it would twist like a banana at that length.
Can only get at one side of the wood... it's a tree on a slope....

UK Tools came up with the 16mm Famag Lewis 1000mm auger and a 400mm extension - neither on their website, I had to ask.

Then I wanted an auger file for sharpening this one and others.
There seems to be no one making them any more. The throwaway society n'all that.
I managed to find one in the US, on Amazon.

Gong to be pricey holes, one way and another.

Opening up with an auger bit?

Inherited a long drill , someone had taken a threaded rod and welded it to the end of a 16mm HSS bit , came in handy when I had to drop power cable down into stud wall from the loft .
