I have a Mark V and would like to know what the actual RPM's are for
the various dial settings..
Anyone have that?
Thank you...Danny

Be aware that whatever numbers you get - they are approximations at best.
If you need to know precisely, you'll have to measure them but the numbers given here are reasonable approximations.

After reading a different thread about this awhile back I bought a digital tach.
I was concerned when it seemed the forstner bits were heating up on the low speed.
My range is 1) at SLOW 900 and 2) FAST 5625. Consequently, I checked each letter and I need to use a lower letter by at least two and in a few cases three to match some of SS recommended letter speeds.
For any application where SLOW or A is recommended I just have to make adjustments for a slower feed or lighter drill pressure.

Try doing a high speed limit adjustment to 5200 and re check.
Curious where the motor belt(yours) currently rides on the pulley at high speed.
