I dounbt I'd buy that drill bit, I'm usually buying bits of less than 4mm D and less than a couple of quid each.

You won't get a carbide tipped engineering drill of that size listed much
cheaper than RS.

For instance

https://www.drill-service.co.uk/prod...-drill-jobber/

I'm not clear on what we are comparing here. Maybe it's just the
description that RS is using. The Drill-Service bits appear to me to be
/solid/ tungsten carbide (linked from
https://www.drill-service.co.uk/products/drills/carbide-drills/). The
RS ones are HSS with a carbide tip (as stated at
https://uk.rs-online.com/web/p/twist-drill-bits/3865298/ and shown in
the photo on that page). Or have I got that wrong?

It was my bad choice of link

https://www.cromwell.co.uk/shop/cutt...etric-/f/68086

Exact same Dormer A160 drill, similar price

For a tipped drill those are indeed relatively expensive compared to solid
carbide from the likes of Guhring, Kyocera and Dormer. (circa 30 quid list for
a 6mm drill)
