spares?

Does the cutting shank part of it look like a Rippa end mill? ie like an
ordinary helix end mill with chip breakers on the teeth? Aldi & Lidl
are always selling little sets of these things which might be
imperially sized.

(Ah, found a picture, the gold coloured bits is what I'm thinking of:

No - I'd call those rotary files. There are two bits that came with it -
one is a conventional router bit, the other a strange looking almost twist
drill - which is designed to cut sideways too. Probably tungsten by the
way it snapped - but wasn't blunt.

Mmm. helical flute?
