Water cooled vs Air cooled spindle for wood

[Clive S]

I hope this isn't a stupid question (if so please go gentle on me as I'm a newbie lol) but are the water cooled spindles suitable for using with wood & MDF etc? I'm assuming all the water is contained & doesn't reach the workpiece? or at leased in theory anyway!

Yes the water cooled spindles are fit for what you are doing plus they are very quiet you will need a small pump and a container for the water the 2.2Kw are generally the ones to go for with a ER20 collet
