I currently have an huanyang 800w water cooled spindle with an er11 collet and I need a way to chew through material faster and cut larger pieces. I’m doing large horns for loudspeakers so I’m doing lots of roughing and fine contours to shape the flare.
I was looking on Amazon, and they have collet adapters that could convert the spindle to a er16 collet and I would be able to use 3/8” bits. Is this feasible? My spindle draws no more than two amps during hard cuts so I know I have more power available. Can the machine handle a 3/8” bit? The one I’m looking at has a 150ipm federate.
Also, what is the consensus on these adapters. Are they safe to use? I’ve heard conflicting information but it seems most people don’t think they are safe.
