Lately, more and more forum users, are getting into waterblock making & machining, but don't know the optimal parameters for machining. So I decided to make thread that will have all data needed in one place.

I will only focus on copper and aluminium, (if someone need any other material just let me know)

So first up is drilling :

rpm are taken from medium cutting speed: and you can calculate your rpm like this: n = vc * 1000 / d* Pi
Where: n = rpm [min-1]
vc= cutting speed [m/min]
d= bit diameter [mm]

Coolin aditives for copper is emulsion (is this the right word) mixture of water, cutting oil and soap
or pure cutting oil.

And for aluminium use emulsion.

Type of drill: N means normal drilling bit, W means drilling bit for softer materials.

UPDATE

Here are parameters for smoth chanell milling

Milling depth shouldn't be greater then 0.5* diameter of the bit

UPDATE

Parameters for smooth face milling, with end mills

Milling depth shouldn't be greater then 1.5* diameter of end mill

UPDATE
This is the table for dimension conversion from fraction-decimal-milimeters, provided by Fixittt
