Ideal drill RPM
« on: December 27, 2008, 11:45:45 AM »
I have an old AMF 2500 drill. Gets light duty use. I can't keep a large bit sharp. By my math, it is running about 900-1000 RPM which seems very fast. I'm going to try to swap out some pulleys to get it down to a slower speed. What is the ideal RPM for a drill today. The small bits are fine but when I have to remove alot of material it just seems way to fast.

Thanks

The bigger the drill, the slower the RPM is.

^^^^^^^^^^^^^^^^^^^^^^^^
WRONG ANSWER.

If the press is spinning an 500RPM, all the bits spin at 500RPM............

Hes saying that the larger the bit the slower you SHOULD be using it. Smaller bits can use faster speeds

Cmurder is right on.
The ideal speed of a ball drilling machine is 500 rpms.
This is the best speed for making your bits last longer.
