Possible to add thru-spindle coolant to 2000 Arrow 750?

I know this was an option, but ours doesn't have it. We have a 300 psi coolant pump, and would like to have it go through the spindle. Maybe on a valve so we can select? Anyone done this before?

The spindle required for TSC is different that non TSC spindles.
You can get toolholders that add TSC. Probably a much cheaper option than changing out the spindle.

You need more than 300 PSI for TSC though.

If your machine is like my Arrow 1000, the drawbar is already hollow and threaded for the rotary union. I checked with MAG for the entire parts kit, and it will run about $5500 for all the pieces from them and about 8 weeks as I recall.

I haven't gone that direction yet, still looking at some other alternative maybe....
