Hi, if you want high speed for small tooling why not use one of the speed
spindles that chucks up like a collet and provides high rpm. some are air
powered some are universal motor. I see them quite often on Ebay for
reasonable $. running a bridgeport at 4000 rpm with a high load cutter is
the best way to kill a nice head. cul brian f.
