Nothing to do with exhausts, but what's the best way to drill a 8mm hole in 25mm tubing? Will 4.5mm work for the pilot, then 8mm? How do you stop the drill bit from wandering on the tube, punch it first??

Lube. It’s the answer to everything.

Not required in this instance, it also makes for more cleanup when welding sanitary stainless. Cutting fluid definitely recommend for many other types of drilling though 😃

hes not telling the truth of how to do this. you need to use a carbide drill bit to start the hole with cuttimg oil. then once the hole is started you can use a variable drill bit on slow speed with cutting oil. or burn it through with a torch. do not do what this guy is doing. he only got lucky.
