A couple of years ago I purchased some long reach Centre Drill Bits from Gloster Tools. However, they don’t appear on their new(ish) website, and two e-mails to them have failed to get a response. I’ve tried the usual suspects without success. Has anyone any suggestions for a supplier?
MSC have them in various lengths and diameters both metric and imperial.
Bernards method is OK for soem jobs but not when you want to do someting like the rod guide hole on the far end of a steam chest where you only have a small entry hole.
Or on a job like this, starting a hole through a previous one that can be reamed to help guide the long bit.
I’ve never used them myself, but they get good reviews from other forum members.

I use them for all my slot drills and end mill cutters (and a few long series centre drills). They are very reliable and give a same day service using first class mail. Locally that means getting the cutters etc next day is in the hands of the gods.
Although I too much prefer a spot drill the price of long series ones is a bit silly, take a look at the ones on teh Drill Services site as an example.
Some of the standard length spotting drills may get you deep enough I have a 4mm dia x 50mm long and a 6mm x 70mm long which can be handy, the 4mm gets used when a cross hole is close to a collet or the spin indexer and anything shorter will see the chuck crash unless the work is sticking out a long way.
The 4mm spotting drill here being used in a similar way to the image of a long ctr drill I posted earlier
