The average speed of a cordless drill is measured in RPM (revolutions per minute). It can vary depending on the model and type of drill, but common speeds range from 500 RPM to 2000 RPM for most cordless drills.
Modern dental drill at 500,000 rpm
The speed at which a drill spins can vary depending on the model and type of drill. Generally, drill speeds can range from around 500 RPM (Revolutions Per Minute) for low-speed drills to over 3000 RPM for high-speed drills. Some specialized drills can even exceed 10,000 RPM.
About 400,000 RPM
Use a standard HSS drill bit, but slow down rotation to about 500 rpm.
Yes, you can drill Lucite. Keep to a fairly low speed so as not to melt it (below 500 rpm.)
In a bowl of water use a diamond tip drill and cover the stone with water. you need to use the drill with very little pressure and drill half way then drill from other side to keep from breaking out the sufface of the hole. The drill RPM needs to be at least 10,000 - 15,000 RPM.
