Generally, you want the rim speed of cutters to stay above 5000ft and below 10000ft per minute otherwise you get into trouble with wood cutting gear. An old-style Whitehill block 5" cutter block spinning at 6000RPM has a rim speed of around 7500ft per minute which means a cutter ejects from the block at around 85MPH give or take. You'd never spin a 2" bit at 30,000RPM as it would just burn and wreck the cutters in double time. I'd probably spin it at 15,000RPM maximum which would also have a rim speed of around 7500ft per minute.There must be better ways to die. That type of clamped cutter was banned from spindles thirty years ago and they only spin at 5-10,000RPM
In a router that can go 30,000, I would not want to be anywhere near
You'd never use it free-hand routing because that would be a complete death wish even with a fence. It would work very nicely in a router table at slower speeds and I could see that it would be very handy for replicating really small and detailed profiles basically working as a smaller scale spindle moulder.That cutter block in a router would be almost as stupid.
Someone with deeper pockets than myself, evidently!Who on earth paid anything for it, not to mention over £80?!
