Hi,
I received many parts for my efoil project (waterproof box with batteries+esc put on a Gong inflatable wing foil) and now I need to drill it to put the metal cable gland PG16 but I am scared to fail the drilling (hole too big or not clean…)
Here is the box :
Here is the cable gland PG16:
Apparently I need to drill a hole of :22.5mm
How to it the best way (without specific equipment) ?
Should I use:
-
a flat wood drill of 22mm (couldn’t find 22.5mm)
-
a 22mm helicoîdal drill for wood
-
a HSS 22mm helicoidal drill for metal
-
a special flat drill for wood
-
a 22mm hole saw
Any advice ?
Thank you for your help
