Drilling stainless ??

andrew2986:
I want to modify the stainless cb arial mount, can any one let me know what type of drill bit I should use? standard HSS bits just go blunt

Cheers

Andy

wormster:
As I recall from my engineering days (many moons ago) stainless is a pig to machiene,

you need a hard bit ground to the right angle run the tool slowly with LOTS of lubrication.

Sharpshooter:
Correct wormster. It might pay you to go up in stages too. :)
