Ok, that makes sense - What is a good kit to get with a water cooled spindle, as the Electric fan air cooled are a lil out of my budgeto

A question I have to ask is and no one ever mentions it when picking out a spindle is, what is the maximum router bit shank size that it will accept. I went with a 3 1/4hp variable speed router so I could use a full range of bit sizes with it ( 1/8" to 1/2" collets) I've not seen any spindle motors that will take a 1/2" bit except for the very very pricey spindles.

My 2.2kw 'China special' spindle has the er20 collet structure. I use 1/2" shank bits everyday in my spindle. Wasn't super expensive either. <shrug>

Thanks for clearing that up. I knew that er11 and er16 collets were being used but was unaware of the er20s. I'm very happy with the performance of my porter cable router so I never really investigated the spindles with vfds. My bad. :cheers:
