Airhole drilling

[EU6EN3]

Hey bro. You know where to get the bits? Can't seem to find 1.5mm cobalts.

BRO.. GO HOMEFIX or DIY store.. Look under black & decker. very cheap only.. Just 1.70. buy a few standby

For those who just wanna drill the CAP.. HSS drill bits more than enough. You can even file it open with a hand file..

So guys! Recently got into RBAS! Mostly drippers.. But still! Was wondering what are some of your preferred air hole sizes??

I was thinking about going to some machining shop or something to get my top caps widened a little bit more. Any info would be appreciated!

mostly 1mm is the stock air hole size for drippers. Best way is to gradually increase by 0.5mm and max at 2.5 (cloud chasing) depending on your preference. You can also try purchasing different cover to drill different sizes.
